drm/sun4i: tcon: fix check of tcon->panel null pointer
Since tcon->panel is a pointer returned by of_drm_find_panel() need to
check if it is not NULL, hence a valid pointer.
IS_ERR() instead checks return error values, not NULL pointers.

Substitute "if (!IS_ERR(tcon->panel))" with "if (tcon->panel)".

6a8915d0f8 drm/i915: Don't oops during modeset shutdown after lpe audio deinit
We deinit the lpe audio device before we call
drm_atomic_helper_shutdown(), which means the platform device
may already be gone when it comes time to shut down the crtc.
As we don't know when the last reference to the platform
device gets dropped by the audio driver we can't assume that
the device and its data are still around when turning off the
crtc. Mark the platform device as gone as soon as we do the
audio deinit.

2c2f6e30d5 drm/i915/glk: Remove 99% limitation.
While checking the opportunity to add a display_gen
check to allow glk and cnl to be on same bucket I noticed
these FIXME cases here.

So I got the confirmation from HW architect that we actually
never needed this workaround.

"GLK supports 2 pixel per clock, so pixel clock can be up to 2 * cdclk."

So, this reverts commit 97f55ca5b6 ("drm/i915/glk: limit pixel
 clock to 99% of cdclk workaround")

The 16Gb DIMM w/a is not applicable to BXT or GLK. Limit it to
the appropriate platforms.

This was especially harsh on GLK since we don't even try to read
the DIMM information on that platforms, hence valid_dimm was
always false and thus we always tried to apply the w/a.
Furthermore the w/a pushed the level 0 latency above the
level 1 latency, which doesn't really make sense.

bfe60a0272 drm/i915/icl: Enable Plane Input CSC for YUV to RGB Conversion
Plane input CSC needs to be enabled to convert frambuffers from
YUV to RGB. This is needed for bottom 3 planes on ICL, rest of
the planes have hardcoded conversion and taken care by the legacy
code.

This patch defines the co-efficient values for YUV to RGB conversion
in BT709 and BT601 formats. It programs the coefficients and enables
the plane input csc unit in hardware.

This has been verified and tested by Maarten and the change is working
as expecpted.

v2: Addressed Maarten's and Ville's review comments and added the
coefficients in a 2D array instead of independent Macros.

v3: Added individual coefficient matrix (9 values) instead of 6
register values as per Maarten's comment. Also addresed a shift
issue with B channel coefficient.

v4: Added support for Limited Range Color Handling

v5: Fixed Matt and Maarten's review comments.

v6: Added human readable matrix values for YUV to RGB Conversion along
with just the bspec register values, as per Matt's suggestion.

v7: Refactored the code, move csc coefficient programming function to
intel_sprite.c and made it static as per Ville's review comment.

v8: Addressed Ville's review comment. Called the coefficient programming
from within the skl_program_plane and used I915_WRITE_FW instead of
I915_WRITE.

v9: Fixed Ville's review comments.

a748faea3b drm/i915: Fix ilk+ watermarks when disabling pipes
We're no longer programming any watermarks when we're disabling
a pipe. That means ilk_wm_merge() & co. will keep considering
the any pipe that is getting disabled as still enabled. Thus we
either get no LP1+ watermakrs (ilk-ivb), or we get suboptimal
ones (hsw-bdw).

This seems to have been broken by commit b6b178a772 ("drm/i915:
Calculate ironlake intermediate watermarks correctly, v2."). Before
that we apparently had some difference between the intermediate
and optimal watermarks and so we would program the optiomal ones.
Now intermediate and optimal are identical for disabled pipes
and so we don't program either.

Fix this by programming the intermediate watermarks even for
disabled pipes. We were already doing that for skl+. We'll
leave out gmch platforms for now since those do the merging
in a different manner and should work as is. We'll want to
unify this eventually, but play it safe for now and just put
in a FIXME.

[Why]
When going to full-screen mode commit_planes_for_stream tries to decrease
dcf_deep_sleep value, but safe_to_lower is false, so we don't send the new value
to SMU but dc context gets updated.
Later when dc_post_update_surfaces_to_stream tries to lower dcf_ds when
safe_to_lower is true, this check prevents the message from being sent.

[How]
Remove the check that compares new value with what is stored in dc_context.
This check is not necessary as dcn1_update_clocks already checks if the value
is different from the current dcf_dp value.

0975780913 drm/amd/display: Set gamma not working on MPO planes
[Why]
Set gamma not working on certain planes in MPO configuration
Root cause is that video format (YUV-420) isn't allowed for IGAM where
gamma is applied.
Fix is not easy though:
1. allowing will not work because IGAM is before ICSC so RGB gamma would
be applied on YUV pixels.
2. Moving OS gamma to DGAM or RGAM resulted in weird artifacts.

Ultimately the root cause for these artifacts was due to handling end
points and the fact that YUV->RGB conversion will frequently "overshoot"
FP 1.0 value. DCE  has a single end point and slope, so we would take max.
In nightlight mode, blue channel is reduced, sometimes to flat 0 line,
but red is virtually unchanged. Any "overshot" in blue will be clipped
to 1 (max R,G,B) instead of max blue value.

[How]
Fortunately, this can be fixed on DCN where we have end point and slope
for all three color channels. We cannot fix this problem on DCE.

Other things fixed:
- switch (back) to using RGAM for OS gamma instead of IGAM
- add coeffs for 709 YUV->RGB (we used RGB->YUV for both conversions)
- switch color temperature method to scaled bradford - otherwise we would
have clipping problems that caused us to switch to IGAM for OS gamma
in the first place.
- comments and some minor improvements - there are some more issues but
they will be addressed in separate commits.

6a85538aa0 drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h - part3
[Why]
In DCN we want direct DAL to SMU calls, with as little as
possible interference by pplib. The reason for each pp_smu interface
mapping to 1 SMU message is so we can have the sequencing of different
SMU message in dal and shared across different OS. This will also
simplify debugging as DAL owns this interaction and there's no
confusion about division of ownership.

[How]
Separate the set_hard_min_fclk_by_freq message from the
SMU messages that are sent as part of pp_rv_set_display_requirement.
directly notify min dcfclk to smu part 2

So far, struct ttm_bo_global_ref was the only way of initializing a struct
ttm_bo_global. Providing separate initializer and release functions for
struct ttm_bo_global gives drivers the option of implementing their own
init and release callbacks for drm_global_references of type
DRM_GLOBAL_TTM_BO.

The original functions for initializing and releasing via struct

98e90a34cc drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h - part2
[Why]
In DCN we want direct DAL to SMU calls, with as little as possible
interference by pplib. The reason for each pp_smu interface mapping to
1 SMU message is so we can have the sequencing of different SMU message
in dal and shared across different OS. This will also simplify
debugging as DAL owns this interaction and there's no confusion about
division of ownership.

fc09ab7a76 vga_switcheroo: Fix missing gpu_bound call at audio client registration
The commit 37a3a98ef6 ("ALSA: hda - Enable runtime PM only for
discrete GPU") added a new ops gpu_bound to be called when GPU gets
bound.  The patch overlooked, however, that vga_switcheroo_enable() is
called only once at GPU is bound.  When an audio client is registered
after that point, it would miss the gpu_bound call.  This leads to the
unexpected lack of runtime PM in HD-audio side.

For addressing that regression, just call gpu_bound callback manually
at vga_switcheroo_register_audio_client() when the GPU was already
bound.

drm/sun4i: Add support for H6 HDMI PHY
H6 has Synopsys DWC HDMI 2.0 TX PHY.

There is no freely available documentation for it, only code found in
BSP kernel. However, judging by the code, PHY is very similar to older
Synopsys HDMI PHY described in i.MX6 documentation. Most registers seem
to be the same.

According to i.MX6 documentation, mpll settings are based on pixel clock
and are not specific to each SoC. Because of that, mpll table in this
commit is based on that documentation and not on BSP code. Other PHY
settings were derived from BSP PHY driver code.

PHY, driver has to be reorganized to support them.

Variant structure is expanded to allow differentiation between custom

Since DW HDMI bridge platform data has different fields for custom and
Sysnopsys PHY, function sun8i_hdmi_phy_get_ops() is replaced with
sun8i_hdmi_phy_set_ops().

6ca469e22a Revert "drm/exynos/decon5433: implement frame counter"
This reverts commit 0586feba32

This patch makes it to need get_vblank_counter callback in crtc
to get frame counter from decon driver.

However, drm_dev->max_vblank_count is a member unique to
vendor's DRM driver but in case of ARM DRM, some CRTC devices
don't provide the frame counter value. As a result, this patch
made extension and clone mode not working.

Instead of this patch, we may need separated max_vblank_count
which belongs to each CRTC device, or need to implement frame
counter emulation for them who don't support HW frame counter.

47e22ff1a9 drm: Add connector property to limit max bpc
At times 12bpc HDMI cannot be driven due to faulty cables, dongles
level shifters etc. To workaround them we may need to drive the output
at a lower bpc. Currently the user space does not have a way to limit
the bpc. The default bpc to be programmed is decided by the driver and
is run against connector limitations.

Creating a new connector property "max bpc" in order to limit the bpc.
xrandr can make use of this connector property to make sure that bpc does
not exceed the configured value. This property can be used by userspace to
set the bpc.

042bf75384 drm/fourcc: Add char_per_block, block_w and block_h in drm_format_info
For some pixel formats .cpp structure in drm_format info it's not
enough to describe the peculiarities of the pixel layout, for example
tiled formats or packed formats at bit level.

What's implemented here is to add three new members to drm_format_info
that could describe such formats:

- char_per_block[3]
- block_w[3]
- block_h[3]

char_per_block will be put in a union alongside cpp, for transparent
compatibility  with the existing format descriptions.

Regarding, block_w and block_h they are intended to be used through
their equivalent getters drm_format_info_block_width /
drm_format_info_block_height, the reason of the getters is to abstract
the fact that for normal formats block_w and block_h will be unset/0,
but the methods will be returning 1.

Additionally, convenience function drm_format_info_min_pitch had been
added that computes the minimum required pitch for a given pixel
format and buffer width.

Using that the following drm core functions had been updated to
generically handle both block and non-block formats:

- drm_fb_cma_get_gem_addr: for block formats it will just return the
  beginning of the block.
- framebuffer_check: Use the newly added drm_format_info_min_pitch.
- drm_gem_fb_create_with_funcs: Use the newly added
  drm_format_info_min_pitch.
- In places where is not expecting to handle block formats, like fbdev
  helpers I just added some warnings in case the block width/height
  are greater than 1.

Changes since v3:
 - Add helper function for computing the minimum required pitch.
 - Improve/cleanup documentation

Changes since v8:
 - Fixed build on 32bits arm architectures, with:

-       return DIV_ROUND_UP((u64)buffer_width * info->char_per_block[plane],
+       return DIV_ROUND_UP_ULL((u64)buffer_width * info->char_per_block[plane],

fcec4163af drm/panel: Add simple panel mode for the ARM RTSM
Having failed any attempts at a more generic solution,
I fall back to the very specific solution: define a simple
panel for the ARM RTSM emulated platforms.

I am doing this so we can convert all old users from the
previous fbdev driver to the PL111 DRM driver.

This works fine as far as I can test, provided the
device tree for RTSM AEMv8 is augmented accordingly.

74c1e82642 drm/i915: remove palette_offsets from device info in favor of _PICK()
The device info offset arrays for unevenly spaced register offsets is
great for widely used registers. However, the palette registers are only
used in one function, i9xx_load_luts_internal(), and only for GMCH
platforms, wasting device info. Replace palette_offsets with _PICK() in
palette register definition.

While the use of _PICK() does not check for pipe C existence, neither
does the current offset array usage, and leads to bogus address when
pipe C is passed to PALETTE() on non-CHV. Using _PICK() at least leads
to a sensible register offset, just non-existing on non-CHV. Either way,
this shouldn't happen anyway.

Remove unused old palette macros while at it.

Bloat-o-meter results below for completeness.

c7375d9542 drm/i915: Configure AUX_CH_CTL when enabling the AUX power domain
Most of the AUX_CH_CTL flags are concerned with DP AUX transfer
parameters. As opposed to this the flag specifying the thunderbolt vs.
non-thunderbolt mode of the port is not related to AUX transfers at all
(rather it's repurposed to enable either TBT or non-TBT PHY HW blocks).
The programming has to be done before enabling the corresponding AUX
power well, so make it part of the power well code.

v3:
- Use existing enable/disable helpers instead of opencoding. (Jose)
- Fix type of is_tc_tbt to remain a bitfield. (Lucas)
- Add comment describing the is_tc_tbt power well flag. (Lucas)

ac897d6bd7 drm/i915: Init aux_ch for HDMI ports too
From ICL onwards DDI/TypeC ports - even in HDMI static mode - need to know
which AUX CH belongs to them, so initialize aux_ch for those ports too.
For consistency do this for all HDMI ports, not only for DDI/TypeC ones.

But also it is written there that we don't need this WA

Turns out there was a typo introduced by

amdgpu_fence_driver_force_completion and so the hangged job

45cf87566e drm/tilcdc: Use drm_fbdev_generic_setup()
The CMA helper is already using the drm_fb_helper_generic_probe part of
the generic fbdev emulation. This patch makes full use of the generic
fbdev emulation by using its drm_client callbacks. This means that
drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are
now handled by the emulation code. Additionally fbdev unregister happens
automatically on drm_dev_unregister().

The drm_fbdev_generic_setup() call is put after drm_dev_register() in the
driver. This is done to highlight the fact that fbdev emulation is an
internal client that makes use of the driver, it is not part of the
driver as such. If fbdev setup fails, an error is printed, but the driver
succeeds probing.

03ad7d8821 drm/i915/ICL: Add pre_pll_enable hook for ICL and set DFLEXDPMLE in this hook
In case of Legacy DP connector on TypeC port, the
flex IO DPMLE register is set to number of lanes configured
by the display driver which will be programmed into DDI_BUF_CTL
PORT_WIDTH_SELECTION.
This needs to be programmed before enabling the shared PLLs hence
add a pre_pll_enable hook for ICL and add this programming in that hook.

v2:
* Remove the check for combophy port (Jose)
* Simplify the port reversal check logic (Jose)

The main benefit is consistent debug logging when we turn off the

The second benefit is consistency; This is what we do for all

93ac092f05 drm/i915/dp: Cache the DP/eDP DSC DPCD register set on Hotplug/eDP Init
DSC is supported on eDP starting GEN 10 display (on GLK) and on DP starting
GEN 11.
This patch implements the discovery phase of DSC. On hotplug,
source reads the DSC DPCD register set (0x00060 - 0x0006F) to
read the decompression capabilities of the sink device.
This entire block of registers is cached in intel_dp so that
capability information can be used during DSC configuration
phase during compute_config phase of the modeset.
For eDP, this caching happens during the eDP initialization.
This caching is done only for eDP and DP rev >= 1.4

v5:
* Fix the block comment (Gaurav)
* Fix the commit message DSC DPCD addresses (Gaurav)
* Use DRM_ERROR for dpcd_read fail (Gaurav,Anusha)
v4:
* Cache these only for Gen >= 11
v3:
* Remove the dsc_sink_support field in intel_dp (Jani N)
v2:
* Clear the cached registers on hotplug always (Jani N)
* Combine the eDP and DP caching in same function (Jani N)

5a4712f472 drm/i915/icl: Program HS_TX_TIMEOUT/LP_RX_TIMEOUT/TA_TIMEOUT registers
Program the timeout values (in escape clock) for HS TX, LP RX and TA
timeout.

HX TX: Ensure that host does not continuously transmit in the HS
state. If this timer expires, then host will gracefully end its HS
transmission and allow the link to enter into LP state.

LP RX: Monitor the length of LP receptions from Peripheral. If timeout
happens then host will drive the stop state onto all data lanes (only
Data Lane 0 should be receiving anything from the Peripheral). This
effectively takes back ownership of the bus transmit in the HS state.

TA timeout: Timeout valuefor monitoring Bus Turn-Around (BTA) sequence.
BTA sequence should complete within a bounded amount of time, with
peripheral acknowledging BTA by driving the stop state.

v2 by Jani:
 - Rebase
 - Use intel_dsi_bitrate() and intel_dsi_tlpx_ns(intel_dsi)
 - Squash HX TX, LP RX and TA timeout into one patch
 - Fix bspec mode set sequence reference
 - Add FIXME about two timeouts

32bbc3d450 drm/i915/icl: Wait for header/payload credits release
Driver needs payload/header credits for sending any command
and data over DSI link. These credits are released once command
or data sent to link. This patch adds functions to wait for releasing
of payload and header credits.

As per BSPEC, driver needs to ensure that all of commands/data
has been dispatched to panel before the transcoder is enabled.
This patch implement those steps i.e. sending NOP DCS command,
wait for header/payload credit to be released etc.

v2 by Jani:
 - squash the credit wait helpers patch with the first user
 - pass dev_priv to the credit wait helpers
 - bikeshed credit helper names
 - wait for *at least* the current maximum number of credits
 - indentation fix
 - add helpers for credits available
