This way the drm_bridge_funcs interface is consistent with the rest of
the subsystem.
The only driver implementing those hooks (analogix DP) is patched too.

The probe function needs to get ahold of the panel device tree
node, and it achieves that by using a combination of
of_graph_get_port_by_id, of_get_child_by_name, and
of_graph_get_remote_port_parent. We can achieve the same goal
by replacing those calls with a call to of_graph_get_remote_node
these days.

If implementation-specific phy_ops need to be defined they probably
should be enabled before trying to talk to the panel and disabled only
after the panel was disabled.
Right now they are enabled last and disabled first, so might make it
impossible to talk to some panels - example for this being the px30
with an external Innosilicon dphy that needs the phy to be enabled
to transfer commands to the panel.
So move the calls appropriately.

The timing values for dw-dsi are often dependent on the used display and
according to Philippe Cornu will most likely also depend on the used phy
technology in the soc-specific implementation.
To solve this and allow specific implementations to define them as needed
add a new get_timing callback to phy_ops and call this from the dphy_timing
function to retrieve the necessary values for the specific mode.
Right now this handles the hs2lp + lp2hs where Rockchip SoCs need handling
according to the phy speed, while STM seems to be ok with static values.

Avoid the detour around drm_panel by providing a simple get method.
This avoids direct access to the connector field in drm_panel in

Core changes:
- Expose pull up/down flags for the GPIO character device to
userspace. After clear input from the RaspberryPi and Beagle
communities, it has been established that prototyping,
industrial automation and make communities strongly need
this feature, and as we want people to use the character
device, we have implemented the simple pull up/down
interface for GPIO lines. This means we can specify that
a (chip-specific) pull up/down resistor can be enabled,
but does not offer fine-grained control such as cases
where the resistance of the same pull resistor can be
controlled (yet).
- Introduce devm_fwnode_gpiod_get_index() and start to phase out
the old symbol devm_fwnode_get_index_gpiod_from_child().
- A bit of documentation clean-up work.
- Introduce a define for GPIO line directions and deploy it
in all GPIO drivers in the drivers/gpio directory.
- Add a special callback to populate pin ranges when
cooperating with the pin control subsystem and registering
ranges as part of adding a gpiolib driver and a
gpio_irq_chip driver at the same time. This is also
deployed in the Intel Merrifield driver.
New drivers:
- RDA Micro GPIO controller.
- XGS-iproc GPIO driver.
Driver improvements:
- Wake event and debounce support on the Tegra 186 driver.
- Finalize the Aspeed SGPIO driver.
- MPC8xxx uses a normal IRQ handler rather than a chained
handler.

Merge tag 'gpio-v5.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.5 kernel cycle
Core changes:
- Expose pull up/down flags for the GPIO character device to
userspace.
After clear input from the RaspberryPi and Beagle communities, it
has been established that prototyping, industrial automation and
make communities strongly need this feature, and as we want people
to use the character device, we have implemented the simple pull
up/down interface for GPIO lines.
This means we can specify that a (chip-specific) pull up/down
resistor can be enabled, but does not offer fine-grained control
such as cases where the resistance of the same pull resistor can be
controlled (yet).
- Introduce devm_fwnode_gpiod_get_index() and start to phase out the
old symbol devm_fwnode_get_index_gpiod_from_child().
- A bit of documentation clean-up work.
- Introduce a define for GPIO line directions and deploy it in all
GPIO drivers in the drivers/gpio directory.
- Add a special callback to populate pin ranges when cooperating with
the pin control subsystem and registering ranges as part of adding
a gpiolib driver and a gpio_irq_chip driver at the same time. This
is also deployed in the Intel Merrifield driver.
New drivers:
- RDA Micro GPIO controller.
- XGS-iproc GPIO driver.
Driver improvements:
- Wake event and debounce support on the Tegra 186 driver.
- Finalize the Aspeed SGPIO driver.
- MPC8xxx uses a normal IRQ handler rather than a chained handler"

Allow codec driver register callback function for plug event.
The callback registration flow:
dw-hdmi <--- hw-hdmi-i2s-audio <--- hdmi-codec
dw-hdmi-i2s-audio implements hook_plugged_cb op
so codec driver can register the callback.
dw-hdmi exports a function dw_hdmi_set_plugged_cb so platform device
can register the callback.
When connector plug/unplug event happens, report this event using the
callback.

connector status.

max_tu_symbol was programmed to TU_SIZE_RECOMMENDED - 1, which is not

roundup ((input active video bandwidth in bytes/output active video
bandwidth in bytes) * tu_size)
It is not quite clear what the above means, but calculating
max_tu_symbol = (input Bps / output Bps) * tu_size seems to work and
fixes the issues seen.
This fixes artifacts in some videomodes (e.g. 1024x768@60 on 2-lanes &

commit d6abe6df70 ("drm/bridge: sil_sii8620: do not have a dependency
of RC_CORE") changed the driver to select both RC_CORE and INPUT.
However, this causes problems with other drivers, in particular an input
driver that depends on MFD_INTEL_LPSS_PCI (to be added in a separate
commit):
drivers/clk/Kconfig:9:error: recursive dependency detected!
drivers/clk/Kconfig:9: symbol COMMON_CLK is selected by MFD_INTEL_LPSS
drivers/mfd/Kconfig:566: symbol MFD_INTEL_LPSS is selected by MFD_INTEL_LPSS_PCI
drivers/mfd/Kconfig:580: symbol MFD_INTEL_LPSS_PCI is implied by KEYBOARD_APPLESPI
drivers/input/keyboard/Kconfig:73: symbol KEYBOARD_APPLESPI depends on INPUT
drivers/input/Kconfig:8: symbol INPUT is selected by DRM_SIL_SII8620
drivers/gpu/drm/bridge/Kconfig:83: symbol DRM_SIL_SII8620 depends on DRM_BRIDGE
drivers/gpu/drm/bridge/Kconfig:1: symbol DRM_BRIDGE is selected by DRM_PL111
drivers/gpu/drm/pl111/Kconfig:1: symbol DRM_PL111 depends on COMMON_CLK
According to the docs and general consensus, select should only be used
for non user-visible symbols, but both RC_CORE and INPUT are
user-visible. Furthermore almost all other references to INPUT
throughout the kernel config are depends, not selects. For this reason
the first part of this change reverts the commit.
In order to address the original reason for the commit, namely
that not all boards use the remote controller functionality and hence
should not need have to deal with RC_CORE, the second part of this
change now makes the remote control support in the driver optional and
contingent on RC_CORE being defined. And with this the hard dependency
on INPUT also goes away as that is only needed if RC_CORE is defined
(which in turn already depends on INPUT).

The DDC/CI protocol involves sending a multi-byte request to the
display via I2C, which is typically followed by a multi-byte
response. The internal I2C controller only allows single byte
reads/writes or reads of 8 sequential bytes, hence DDC/CI is not
supported when the internal I2C controller is used. The I2C
transfers complete without errors, however the data in the response
is garbage. Abort transfers to/from slave address 0x37 (DDC) with

typical real-world scenario is that where one adapter is used when the
device is in standby, and one that's better/smarter when the device is
powered up.
The cec-notifier changes were made with that in mind, but I missed that in
order to support this you need to tell cec_notifier_cec_adap_unregister()
which adapter you are unregistering from the notifier.
Add this additional argument. It is currently unused, but once all drivers
use this, the CEC core will be adapted for these use-cases.

When transmitting IEC60985 linear PCM audio, we configure the
Aduio Sample Channel Status information in the IEC60958 frame.
The status bit is already available in iec.status of hdmi_codec_params.
This fix the issue that audio does not come out on some monitors
(e.g. LG 22CV241)
Note that these registers are only for interfaces:
I2S audio interface, General Purpose Audio (GPA), or AHB audio DMA
(AHBAUDDMA).
For S/PDIF interface this information comes from the stream.
Currently this function dw_hdmi_set_channel_status is only called
from dw-hdmi-i2s-audio in I2S setup.

This reverts commit 83f35bc3a8.
There are at least two DSI controller drivers which relies on the old
behaviour of adv7511 driver. To avoid platform breakage this patch
should be reverted. This is a temporary solution, as it blocks adv7511
usage with other platforms.
Assumption that DSI device driver (bridge/panel) should first expose
drm_bridge/drm_panel object, then look for DSI bus is just incorrect -
it can work with devices controlled via i2c but it cannot work with
devices controlled via DSI - they will not be able to probe.
To solve the issue following steps should be performed:
- rework reverted patch allowing co-operation with broken DSI controller
drivers - with simple/ugly workaround,
- fix controller drivers and then remove workaround.

The drm panel bridge creates a connector using a connector type
explicitly passed by the display controller or bridge driver that
instantiates the panel bridge. Now that drm_panel reports its connector
type, we can use it to avoid passing an explicit (and often incorrect)
connector type to drm_panel_bridge_add() and
devm_drm_panel_bridge_add().
Several drivers report incorrect or unknown connector types to
userspace. Reporting a different type may result in a breakage. For that
reason, rename (devm_)drm_panel_bridge_add() to
(devm_)drm_panel_bridge_add_typed(), and add new
(devm_)drm_panel_bridge_add() functions that use the panel connector
type. Update all callers of (devm_)drm_panel_bridge_add() to the _typed
function, they will be converted one by one after testing.
The panel drivers have been updated with the following Coccinelle
semantic patch, with manual inspection and fixes to indentation.

If the VGA connector has no DDC channel, an error pointer will be

This happens because vga->ddc either contains a valid DDC channel
pointer, or -ENODEV, and drm_connector_init_with_ddc() expects a valid
DDC channel pointer, or NULL.
Fix this by resetting vga->ddc to NULL in case of -ENODEV, and replacing
the existing error checks by non-NULL checks.
This is similar to what the HDMI connector driver does.

When using an I2S source using a different clock source (usually the I2S
audio HW uses dedicated PLLs, different from the HDMI PHY PLL), fixed
CTS values will cause some frequent audio drop-out and glitches as
reported on Amlogic, Allwinner and Rockchip SoCs setups.
Setting the CTS in automatic mode will let the HDMI controller generate
automatically the CTS value to match the input audio clock.
The DesignWare DW-HDMI User Guide explains:
For Automatic CTS generation
Write "0" on the bit field "CTS_manual", Register 0x3205: AUD_CTS3
The DesignWare DW-HDMI Databook explains :
If "CTS_manual" bit equals 0b this registers contains "audCTS[19:0]"
generated by the Cycle time counter according to specified timing.

To get the chip into the expected state, even when the hardware reset pin
isn't connected, do a software reset in this case. It isn't as thorough as
the hardware reset, as the I2C communication block can not be reset for
obvious reasons, but it's getting the chip into a defined state.

In contrast to all of the DSI panel drivers in drivers/gpu/drm/panel
which attach to the DSI host via mipi_dsi_attach() at probe time, the
ADV7533 bridge device does not. Instead it defers this to the point that
the upstream device connects to its bridge via drm_bridge_attach().
The generic Synopsys MIPI DSI host driver does not register it's own
drm_bridge until the MIPI DSI has attached. But it does not call
drm_bridge_attach() on the downstream device until the upstream device
has attached. This leads to a chicken and the egg failure and the DRM
pipeline does not complete.
Since all other mipi_dsi_device drivers call mipi_dsi_attach() in
probe(), make the adv7533 mipi_dsi_device do the same. This ensures that
the Synopsys MIPI DSI host registers it's bridge such that it is
available for the upstream device to connect to.

Transfer size of zero means a request to do an address-only
transfer. Since the HW support this, we probably shouldn't be just
ignoring such requests. While at it allow DP_AUX_I2C_MOT flag to pass
through, since it is supported by the HW as well.

Don't assume that requested data transfer size is the same as amount
of data that was transferred. Change the code to get that information
from DP0_AUXSTATUS instead.
Since the check for AUX_BUSY in tc_aux_get_status() is pointless (it
will always called after tc_aux_wait_busy()) and there's only one user
of it, inline its code into tc_aux_transfer() instead of trying to
accommodate the change above.

According to the datasheet tc358767 can transfer up to 16 bytes via
its AUX channel, so the artificial limit of 8 appears to be too
low. However only up to 15-bytes seem to be actually supported and
trying to use 16-byte transfers results in transfers failing
sporadically (with bogus status in case of I2C transfers), so limit it
to 15.

Simplify AUX data write by dropping index arithmetic and shifting and
replacing it with a call to a helper function that does two things:
1. Copies user-provided data into a write buffer
2. Transfers contents of the write buffer to up to 4 32-bit
registers on the chip
Note that separate data endianness fix:
tmp = (tmp << 8) | buf[i];
that was reserved for DP_AUX_I2C_WRITE looks really strange, since it
will place data differently depending on the passed user-data
size. E.g. for a write of 1 byte, data transferred to the chip would
look like:
[byte0] [dummy1] [dummy2] [dummy3]
whereas for a write of 4 bytes we'd get:
[byte3] [byte2] [byte1] [byte0]
Since there's no indication in the datasheet that I2C write buffer
should be treated differently than AUX write buffer and no comment in
the original code explaining why it was done this way, that special
I2C write buffer transformation was dropped in this patch.

A very unfortunate aspect of tc_write()/tc_read() macro helpers is
that they capture quite a bit of context around them and thus require
the caller to have magic variables 'ret' and 'tc' as well as label
'err'. That makes a number of code paths rather counter-intuitive and
somewhat clunky, for example tc_stream_clock_calc() ends up being like
this:
int ret;
tc_write(DP0_VIDMNGEN1, 32768);
return 0;
err:
return ret;
which is rather surprising when you read the code for the first
time. Since those helpers arguably aren't really saving that much code
and there's no way of fixing them without making them too verbose to
be worth it change the driver code to not use them at all.

On Rockchip rk3288-based Chromebooks when you do a suspend/resume
cycle:
1. You lose the ability to detect an HDMI device being plugged in.
2. If you're using the i2c bus built in to dw_hdmi then it stops
working.
Let's add a hook to the core dw-hdmi driver so that we can call it in
dw_hdmi-rockchip in the next commit.
NOTE: the exact set of steps I've done here in resume come from
looking at the normal dw_hdmi init sequence in upstream Linux plus the
sequence that we did in downstream Chrome OS 3.14. Testing show that
it seems to work, but if an extra step is needed or something here is
not needed we could improve it.
As part of this change we'll refactor the hardware init bits of
dw-hdmi to happen all in one function and all at the same time. Since
we need to init the interrupt mutes before we request the IRQ, this
means moving the hardware init earlier in the function, but there
should be no problems with that. Also as part of this we now
unconditionally init the "i2c" parts of dw-hdmi, but again that ought
to be fine.

We have tc_connector_mode_valid() to filter out videomdoes that the
tc358767 cannot support. As it is a bridge limitation, change the code
to use drm_bridge_funcs's mode_valid instead.

tc_main_link_enable() checks if videomode has been set, and fails if
there's no videomode. As tc_main_link_enable() no longer depends on the
videomode, we can drop the check.
Also, while tc_stream_enable() does depend on the videomode, we can
expect that a mode has been set before drm_bridge_funcs.enable is
called, so we don't need the check there either.

The current link training code does unnecessary retry-loops, and does
extra writes to the registers. It is easier to follow the flow and
ensure it's similar to Toshiba's documentation if we deal with LT inside
tc_main_link_enable() function.
This patch adds tc_wait_link_training() which handles waiting for the LT
phase to finish, and does the necessary LT register setups in
tc_main_link_enable, without extra loops.

The driver has a loop after ending link training, where it reads the
DPCD link status and prints an error if that status is not ok.
The loop is unnecessary, as far as I can understand from DP specs, so
let's remove it. We can also print the more specific errors to help

At the end of the link training, two steps have to be taken: 1)
tc358767's LT mode is disabled by a write to DP0_SRCCTRL, and 2) Remove
LT flag in DPCD 0x102.
Toshiba's documentation tells to first write the DPCD, then modify
DP0_SRCCTRL. In my testing this often causes issues, and the link
disconnects right after those steps.
If I reverse the steps, it works every time. There's a chance that this
is DP sink specific, though, but as my testing shows this sequence to be
much more reliable, let's change it.

Link training will sometimes fail if the DP link is enabled when
tc_main_link_enable() is called. The driver makes sure the DP link is
disabled when the DP output is disabled, and we never enable the DP
without first disabling it, so this should never happen.
However, as the HW behavior seems to be somewhat random if DP link has
erroneously been left enabled, let's add a WARN_ON() for the case and
set DP0CTL to 0.

Currently the code writes 0 to DP0CTL in tc_stream_disable(), which
disables the whole DP link instead of just the video stream. We always
disable the link and the stream together from tc_bridge_disable(), so
this doesn't cause any issues.
Nevertheless, fix this by only clearing VID_EN in tc_stream_disable to
stop the video stream while keeping the link enabled.

We set up the PXL PLL inside tc_main_link_setup. This is unnecessary,
and makes tc_main_link_setup depend on the video-mode, which should not
be the case. As PXL PLL is used only for the video stream (and only when
using the HW test pattern), let's move the PXL PLL setup into
tc_stream_enable.
Also, currently the PXL PLL is only disabled if the driver if removed.
Let's disable the PXL PLL when the stream is disabled.

sets the main link's number of lanes using tc->link.base.num_lanes. This
is not needed nor correct, as the number of lanes has not been decided
yet. The number of lanes will be set later during main link setup.
Modify aux_link_setup so that it does not use tc->link, and thus makes

DP always uses ANSI 8B10B encoding. Some monitors (old?) may not have
the ANSI 8B10B bit set in DPCD, even if it should always be set.
The tc358767 driver currently respects that flag, and turns the encoding
off if the monitor does not have the bit set, which then results in the
monitor not working.
This patch makes the driver to always use ANSI 8B10B encoding, and drops
the 'coding8b10b' field which is no longer used.

VSC SDP Payload for PSR is one of data block type of SDP (Secondaray Data
Packet). In order to generalize SDP packet structure name, it renames
struct edp_vsc_psr to struct dp_sdp. And each SDP data blocks have
different usages, each SDP type has different reserved data blocks and
Video_Stream_Configuration Extension VESA SDP might use all of Data Blocks
as Extended INFORFRAME Data Byte. so it makes Data Block variables as
array type. And it adds comments of details of DB of VSC SDP Payload
for Pixel Encoding/Colorimetry Format. This comments follows DP 1.4a spec,
section 2.2.5.7.5, chapter "VSC SDP Payload for Pixel Encoding/Colorimetry
Format".

The driver currently sets register 0xfb (Low Refresh Rate) based on the
value of mode->vrefresh. Firstly, this field is specified to be in Hz,
but the magic numbers used by the code are Hz * 1000. This essentially
leads to the low refresh rate always being set to 0x01, since the
vrefresh value will always be less than 24000. Fix the magic numbers to
be in Hz.
Secondly, according to the comment in drm_modes.h, the field is not
supposed to be used in a functional way anyway. Instead, use the helper
function drm_mode_vrefresh().

Pull drm updates from Dave Airlie:
"This has two exciting community drivers for ARM Mali accelerators.
Since ARM has never been open source friendly on the GPU side of the
house, the community has had to create open source drivers for the
Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
series. Well done to all involved and hopefully this will help ARM
head in the right direction.
There is also now the ability if you don't have any of the legacy
drivers enabled (pre-KMS) to remove all the pre-KMS support code from
the core drm, this saves 10% or so in codesize on my machine.
i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
moves out of staging.
There are also some rcar-du patches which crossover with media tree
but all should be acked by Mauro.

- ability to remove legacy support code if no drivers requires it (removes 10% of drm.ko size)
- lease fixes
ttm:
- unified DRM_FILE_PAGE_OFFSET handling
- Account for kernel allocations in kernel zone only

The TFP410 supports 24 bit, single-edge and 12 bit, dual-edge modes.
Depending on how many wires are used (24/12) the driver can set the correct
bus_format.
If the information is not available in DT then assume 24 bit, single-edge
setup.

In case either the HPD gpio is not specified or when the HPD gpio can not
be used as interrupt we should tell the core that the HPD needs to be

We have two *_CLASS_DEVICE kernel config options (LCD_CLASS_DEVICE
and BACKLIGHT_LCD_DEVICE) that do the same job.
The patch removes useless BACKLIGHT_LCD_SUPPORT option
and converts LCD_CLASS_DEVICE into a menu.

This patch is an attempt to limit HDMI 2.0 SCDC setup when :
- the SoC embeds an HDMI 1.4 only controller
- the EDID supports SCDC but not scrambling
- the EDID supports SCDC scrambling but not for low TMDS bit rates,
while only supporting low TMDS bit rates
This to avoid communicating with the SCDC DDC slave uncessary, and
setting the DW-HDMI TMDS Scrambler setup when not supported by the
underlying hardware.

The TFP410 supports configurable pixel clock sampling edge and data
de-skew adjustments. The configuration can be set through I2C or
dedicated chip pins.
Report the configuration through the drm_bridge timings. As the
ti-tftp410 driver doesn't support configuring the chip through I2C, we
simply use the default configuration in that case. When the chip is
configured through dedicated pins, we parse the configuration from DT.

The TFP410 has a powerdown pin that can be connected to a GPIO to
control power saving. The DT bindings define a corresponding property,

The TI TFP410 is a DVI encoder, not a full HDMI encoder. Its output can
be routed to a DVI-D connector, even if in many cases embedded systems
will use an HDMI connector to carry the DVI signals.
Instead of hardcoding the connector type to HDMI, retrieve the connector
type from its DT node.

The DRM bus flags convey additional information on pixel data on
the bus. All current available bus flags might be of interest for
a bridge. Remove the sampling_edge field and use bus_flags.
In the case at hand a dumb VGA bridge needs a specific data enable
polarity (DRM_BUS_FLAG_DE_LOW).

The DRM_BUS_FLAG_PIXDATA_(POS|NEG)EDGE and
DRM_BUS_FLAG_SYNC_(POS|NEG)EDGE flags are deprecated in favour of the
new DRM_BUS_FLAG_PIXDATA_(DRIVE|SAMPLE)_(POS|NEG)EDGE and
new DRM_BUS_FLAG_SYNC_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags. Replace them
through the code.
This effectively changes the value of the .sampling_edge bridge timings
field in the dumb-vga-dac driver. This is safe to do as no driver
consumes these values yet.

Lots and lots of new drivers so far, a highlight being the MediaTek
BTCVSD which is a driver for a Bluetooth radio chip - the first such

with an upstream driver!
- Support for only powering up channels that are actively being used.
- Quite a few improvements to simplify the generic card drivers,
especially the merge of the SCU cards into the main generic drivers.
- Lots of fixes for probing on Intel systems, trying to rationalize
things to look more standard from a framework point of view.
- New drivers for Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341,
Google ChromeOS embedded controllers, Ingenic JZ4725B, MediaTek
BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328, Spreadtrum

In order to support the HDMI2.0 YUV420 display modes, this patch

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.
To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.
v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.
v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.
This will also conflict with ongoing drmP.h cleanup by others I
expect.
v3: Rebase on top of atomic bochs.
v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
other places (all suggested from Laurent adopted unchanged).
- sort alphabetically
v5: Actually try to sort them, and while at it, sort all the ones I
touch.
v6: Rebase onto i915 changes.
v7: Rebase once more.
