31b4c8848a drm/bridge: tc358767: remove unnecessary msleep
For some reason the driver has a msleep(100) after writing to
DP_PHY_CTRL. Toshiba's documentation doesn't suggest any delay is
needed, and I have not seen any issues with the sleep removed.

Drop it, as msleep(100) is a rather big one.

67bca92fa8 drm/bridge: tc358767: ensure DP is disabled before LT
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.

1c928267b1 drm/bridge: tc358767: disable only video stream in tc_stream_disable
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.

cb3263b2df drm/bridge: tc358767: add link disable function
Currently we have tc_main_link_setup(), which configures and enabled the
link, but we have no counter-part for disabling the link.

Add tc_main_link_disable, and rename tc_main_link_setup to
tc_main_link_enable.

bb24836869 drm/bridge: tc358767: move PXL PLL enable/disable to stream enable/disable
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.

5761a259aa drm/bridge: tc358767: move video stream setup to tc_main_link_stream
The driver currently sets the video stream registers in
tc_main_link_setup. One should be able to establish the DP link without
any video stream, so a more logical place is to configure the stream in
the tc_main_link_stream. So move them there.

ca342386a9 drm/bridge: tc358767: cleanup aux_link_setup
The driver sets up AUX link at probe time, but, for some reason, also
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
aux setup independent of the link probing.

4b30bf41e1 drm/bridge: tc358767: fix ansi 8b10b use
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.

4d432f956d drm: Rename struct edp_vsc_psr to struct dp_sdp
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".

v7: Addressed review comments from Ville.

v9: Rename a member value name DB to db on struct dp_sdp [Laurent]

67793bd3b3 drm/bridge: adv7511: Fix low refresh rate selection
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

hdmi->i2c may not be set when ddc-i2c-bus property is used in device tree.
Fix this by using hdmi->ddc as the i2c adapter when calling drm_scdc_*().
Also report that SCDC is not supported when there is no DDC bus.

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

If the information is not available in DT then assume 24 bit, single-edge

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.

Report the configuration through the drm_bridge timings. As the

simply use the default configuration in that case. When the chip is

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.

d02cac152c ASoC: Updates for v5.1
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
 driver we've had upstream.  Hopefully we will soon also see a baseband
 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

ba9877e236 drm/bridge: dw-hdmi: add support for YUV420 output
In order to support the HDMI2.0 YUV420 display modes, this patch
adds support for the YUV420 TMDS Clock divided by 2 and the controller
passthrough mode.

YUV420 Synopsys PHY support will need some specific configuration table
to support theses modes.

This patch is based on work from Zheng Yang <zhengyang@rock-chips.com> in
the Rockchip Linux 4.4 BSP at [1]

fcd70cd36b drm: Split out drm_probe_helper.h
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.

Add code to reject modes that require more bandwidth that is available.

9a63bd6fe1 drm/bridge: tc358767: fix initial DP0/1_SRCCTRL value
Initially DP0_SRCCTRL is set to a static value which includes
DP0_SRCCTRL_LANES_2 and DP0_SRCCTRL_BW27, even when only 1 lane of
1.62Gbps speed is used. DP1_SRCCTRL is configured to a magic number.

This patch changes the configuration as follows:

Configure DP0_SRCCTRL by using tc_srcctrl() which provides the correct
value.

DP1_SRCCTRL needs two bits to be set to the same value as DP0_SRCCTRL:
SSCG and BW27. All other bits can be zero.

Quite obviously the driver depends on I2C_MUX, but adding a "depends on"
introduces a recursive dependency, therefore this patch selects I2C_MUX
instead.

21d808405f drm/bridge/sii902x: Fix EDID readback
While adding SiI9022A support to the iwg23s board, it came
up that when the HDMI transmitter is in pass through mode the
device is not compliant with the I2C specification anymore,
as it requires a far bigger tbuf, due to a delay the HDMI
transmitter is adding when relaying the STOP condition on the
monitor i2c side of things.

When not providing an appropriate delay after the STOP condition
the i2c bus would get stuck. Also, any other traffic on the bus
while talking to the monitor may cause the transaction to fail
or even cause issues with the i2c bus as well.

I2c-gates seemed to reach consent as a possible way to address
these issues, and as such this patch is implementing a solution
based on that. Since others are clearly relying on the current
implementation of the driver, this patch won't require any DT
changes.

Since we don't want any interference during the DDC Bus
Request/Grant procedure and while talking to the monitor, we
have to use the adapter locking primitives rather than the
i2c-mux locking primitives.

Allow to also drive a slave dw-mipi-dsi controller in a dual-dsi
setup. This will require additional implementation-specific
code to look up the slave instance and do specific setup.
Also will probably need code in the specific crtcs as dual-dsi
does not equal two separate dsi outputs.

To activate, the implementation-specific code should set the slave
using dw_mipi_dsi_set_slave() before calling __dw_mipi_dsi_bind().

v2:
- expect real interface number of lanes
- keep links to both master and slave
v3:
- remove unneeded separate variables
- remove unneeded second slave settings

90910a6511 drm/bridge/synopsys: dsi: add ability to have glue-specific attach and detach
With the regular means of adding the dsi-component in probe it creates
a race condition with the panel probing, as the panel device only gets
created after the dsi-bus got created.

When the panel-driver is build as a module it currently fails hard as the
panel cannot be probed directly:

dw_mipi_dsi_bind()
  __dw_mipi_dsi_probe()
    creates dsi bus
    creates panel device
    triggers panel module load
    panel not probed (module not loaded or panel probe slow)
  drm_bridge_attach
    fails with -EINVAL due to empty panel_bridge

Additionally the panel probing can run concurrently with dsi bringup
making it possible that the panel can already be found but dsi-attach
hasn't finished running.

To solve that cleanly we may want to only create the component after
the panel has finished probing, by calling component_add from the
host-attach dsi callback.

As that is specific to glue drivers, add a new struct for host_ops
so that glue drivers can tell the bridge to call specific functions
after the common host-attach and before the common host-detach run.

f2b0e26465 drm/bridge/synopsys: dsi: don't call __dw_mipi_dsi_probe from dw_mipi_dsi_bind
__dw_mipi_dsi_probe() does all the grabbing of resources and does it using
devm-helpers. So this is happening on each try of master bringup possibly
slowing down things a lot.

Drivers using the component framework may instead want to call
dw_mipi_dsi_probe separately in their probe function to setup resources
early. That way the dsi bus also gets created earlier and also not
recreated on each bind-try, so that attached panels can load their modules
and be probed way before the bridge-attach in the bind call.

So drop the call to __dw_mipi_dsi_probe and modify the function to take
a struct dw_mipi_dsi instead of the platform-device.

c2bfc22388 drm/bridge: ti-sn65dsi86: Remove the mystery delay
Let's solve the mystery of commit bf1178c989 ("drm/bridge:
ti-sn65dsi86: Add mystery delay to enable()").  Specifically the
reason we needed that mystery delay is that we weren't paying
attention to HPD.

Looking at the datasheet for the same panel that was tested for the
original commit, I see there's a timing "t3" that times from power on
to the aux channel being operational.  This time is specced as 0 - 200
ms.  The datasheet says that the aux channel is operational at exactly
the same time that HPD is asserted.

Scoping the signals on this board showed that HPD was asserted 84 ms
after power was asserted.  That very closely matches the magic 70 ms
delay that we had.  ...and actually, in my testing the 70 ms wasn't
quite enough of a delay and some percentage of the time the display
didn't come up until I bumped it to 100 ms (presumably 84 ms would
have worked too).

To solve this, we tried to hook up the HPD signal in the bridge.
...but in doing so we found that that the bridge didn't report that
HPD was asserted until ~280 ms after we powered it (!).  This is
explained by looking at the sn65dsi86 datasheet section "8.4.5.1 HPD
(Hot Plug/Unplug Detection)".  Reading there we see that the bridge
isn't even intended to report HPD until 100 ms after it's asserted.
...but that would have left us at 184 ms.  The extra 100 ms
(presumably) comes from this part in the datasheet:

> The HPD state machine operates off an internal ring oscillator. The
> ring oscillator frequency will vary [ ... ]. The min/max range in
> the HPD State Diagram refers to the possible times based off
> variation in the ring oscillator frequency.

Given that the 280 ms we'll end up delaying if we hook up HPD is
_slower_ than the 200 ms we could just hardcode, for now we'll solve
the problem by just hardcoding a 200 ms delay in the panel driver
using the patch in this series ("drm/panel: simple: Support panels
with HPD where HPD isn't connected").

If we later find a panel that needs to use this bridge where we need
HPD then we'll have to come up with some new code to handle it.  Given
the silly debouncing in the bridge chip, though, it seems unlikely.

One last note is that I tried to solve this through another way: In
ti_sn_bridge_enable() I tried to use various combinations of
dp_dpcd_writeb() and dp_dpcd_readb() to detect when the aux channel
was up.  In theory that would let me detect _exactly_ when I could
continue and do link training.  Unfortunately even if I did an aux
transfer w/out waiting I couldn't see any errors.  Possibly I could
keep looping over link training until it came back with success, but
that seemed a little overly hacky to me.

8faff37409 drm/bridge: dw-hdmi: allow forcing vendor phy-type
In some IP implementations the reading of the phy-type may be broken.
One example are the Rockchip rk3228 and rk3328 socs that use a separate
vendor-type phy from Innosilicon but still report the HDMI20_TX type.

So allow the glue driver to force the vendor-phy for these cases.
In the future it may be necessary to allow forcing other types, but
for now we'll keep it simply to the case actually seen in the wild.

changes in v3:
- only allow forcing vendor type, as suggested by Laurent

eb1d23d71e drm/bridge: analogix_dp: Downgrade "Link Training" messages to dev_dbg
The Analogix DP bridge driver is pretty verbose, and outputs
things like

[  619.414067] rockchip-dp ff970000.edp: Link Training Clock Recovery success
[  619.429233] rockchip-dp ff970000.edp: Link Training success!

each time the display gets unblanked. While it is good to know
that the device is behaving correctly, users already know that
because they can see some video output.

Let's keep these messages for cases where we need to actually
debug the driver (we have dynamic debug to enable them at runtime
if need be), and let's keep the kernel quiet otherwise.

bf1178c989 drm/bridge: ti-sn65dsi86: Add mystery delay to enable()
This patch adds a 70ms mystery delay to the bridge driver in enable.
By experimentation, it seems like it can go anywhere up until we
initiate semi-auto link training. If we don't have the delay, link
training fails.

I tried to root cause this as best I could, but neither the datasheet
for the panel nor the bridge mention a delay of this magnitude in their
timing requirements. So for now, add the mystery delay until someone
figures out a better fix.

Quite obviously the driver depends on DRM_MIPI_DSI.
We can not use depends since the driver configuration uses select,
so we'll have to select the missing dependency instead.
