The DU driver uses the rcar_lvds_clk_enable() and
rcar_lvds_clk_disable() functions enable or disable the pixel clock
generated by the LVDS encoder, as it requires that clock for proper DU
operation. Rename the functions by replacing "clk" with "pclk" to make
it clearer that they related to the pixel clock.

The rcar DU driver on r8a779a0 has a bug causing some specific colors
getting converted to transparent colors, which then (usually) show as
black pixels on the screen.
The reason seems to be that the driver sets PnMR_SPIM_ALP bit in
PnMR.SPIM field, which is an illegal setting on r8a779a0. The
PnMR_SPIM_EOR bit also illegal.
Add a new feature flag for this (lack of a) feature and make sure the
bits are zero on r8a779a0.

DRM_MODE_BLEND_PIXEL_NONE ignores an alpha channel.
Rcar-du driver supports only 3 formats with an alpha channel
(DRM_FORMAT_ARGB1555, DRM_FORMAT_ARGB8888 and DRM_FORMAT_ARGB4444). We
simply override the format passed to VSP1 for blending with the pixel
format without alpha channel.

R-Car DU driver implicitly supports DRM_MODE_BLEND_COVERAGE only.
This adds a support for DRM_MODE_BLEND_PREMULTI. As a consequence,
DRM_MODE_BLEND_PREMULTI becomes the default. If DRM_MODE_BLEND_COVERAGE
is desired, it should be set explicitly.
This behavior comes from how DRM blend mode is supported.
drm_plane_create_blend_mode_property() creates the blend mode property
with the default value of DRM_MODE_BLEND_PREMULTI. This default value
cannot be modified from the atomic driver.

To support DRM blend mode in R-Car DU driver, we must be able to pass

With the move to un-versioned filenames, it becomes more difficult to
know exactly what version of a given firmware is being used. So add
the patch level version number to the debugfs output.
Also, support matching by patch level when selecting code paths for
firmware compatibility. While a patch level change cannot be backwards
breaking, it is potentially possible that a new feature only works
from a given patch level onwards (even though it was theoretically
added in an earlier version that bumped the major or minor version).

There was a misunderstanding in how firmware file compatibility should
be managed within i915. This has been clarified as:
i915 must support all existing firmware releases forever
new minor firmware releases should replace prior versions
only backwards compatibility breaking releases should be a new file
This patch cleans up the single fallback file support that was added
as a quick fix emergency effort. That is now removed in preference to
supporting arbitrary numbers of firmware files per platform.
The patch also adds support for having GuC firmware files that are
named by major version only (because the major version indicates
backwards breaking changes that affect the KMD) and for having HuC
firmware files with no version number at all (because the KMD has no
interface requirements with the HuC).
For GuC, the driver will report via dmesg if the found file is older than
expected. For HuC, the KMD will no longer require updating for any new
HuC release so will not be able to report what the latest expected
version is.

Details:
Currently, when trying to suspend and resume with qxl device，
there are some error messages after resuming,
eventually caused to black screen and can't be recovered.
The first error message:
[ 64.668577][ C3] [drm] driver is in bug mode
This error is due to guest qxl driver
will call qxl_reinit_memslots(qdev) during system resume,
but didn't call qxl_io_reset(qdev) before this,
Then will cause the QXL_IO_MEMSLOT_ADD operation to fail on QEMU,
qxl->guest_bug flag will be set，As a result,
the QXL device can't communicate with guest qxl driver through the IO port.
after fix the first error,can success to resume and login to desktop,
but shortly after that will observe the second error message :
[ 353.095343][ T863] qxl 0000:00:02.0: object_init failed for (262144, 0x00000001)
[ 353.096660][ T863] [drm:qxl_gem_object_create [qxl]] *ERROR* Failed to allocate GEM object (260852, 1, 4096, -12)
[ 353.097277][ T863] [drm:qxl_alloc_ioctl [qxl]] *ERROR* qxl_alloc_ioctl: failed to create gem ret=-12
[ 368.197538][ T863] qxl 0000:00:02.0: object_init failed for (3149824, 0x00000001)
[ 368.197541][ T863] [drm:qxl_alloc_bo_reserved [qxl]] *ERROR* failed to allocate VRAM BO
The problem is caused by calling qxl_ring_init_hdr(qdev->release_ring)
in qxl_drm_resume() function.
When do QXL_IO_RESET,QEMU will call init_qxl_ram(),
so params like prod,cons,notify_on_cons and notify_on_prod
will be set to default value.
Ring push/pop actions for release_ring can be performed normally.
But call qxl_ring_init_hdr(qdev->release_ring)
will eventually set notify_on_prod to number of QXL_RELEASE_RING_SIZE,
affect the value of notify in qxl_push_free_res() function always be false,
QEMU will no longer send events of QXL_INTERRUPT_DISPLAY to the
guest qxl driver，so qxl_ring_pop() will never been called anymore，
and can't do dma_fence_signal(),result to ttm_bo_wait_ctx(bo, ctx)
always return EBUSY,fail to call qxl_bo_create().
Test scenario:
1) start virtual machine with qemu command "-device qxl-vga"
2) click suspend botton to enter suspend mode
3) resume and observe the error message in kernel logs,screen will be black
Let's fix this by reset io and remove the qxl_ring_init_hdr calling.

VGA_IS1_RC is the color mode register (VGA_IS1_RM the one for monochrome
mode, note C vs. M at the end). So when using VGA_IS1_RC make sure the
vga device is actually in color mode and set the corresponding bit in the
misc register.
Reproducible when booting VMs in UEFI mode with some edk2 versions (edk2
fix is on the way too). Doesn't happen in BIOS mode because in that
case the vgabios already flips the bit.

Some panels trigger HPD irq due to noise, the HPD debounce
may be 1.8ms, exceeding the default irq detect window, ~1.4ms.
This patch set HPD irq detection window to 2ms to
tolerate the HPD noise.

git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for v6.1:
UAPI Changes:
Cross-subsystem Changes:
- DMA-buf: documentation updates.
- Assorted small fixes to vga16fb
- Fix fbdev drivers to use the aperture helpers.
- Make removal of conflicting drivers work correctly without fbdev enabled.
Core Changes:
- bridge, scheduler, dp-mst: Assorted small fixes.
- Add more format helpers to fourcc, and use it to replace the cpp usage.
- Add DRM_FORMAT_Cxx, DRM_FORMAT_Rxx (single channel), and DRM_FORMAT_Dxx
("darkness", inverted single channel)
- Add packed AYUV8888 and XYUV8888 formats.
- Assorted documentation updates.
- Rename ttm_bo_init to ttm_bo_init_validate.
- Allow TTM bo's to exist without backing store.
- Convert drm selftests to kunit.
- Add managed init functions for (panel) bridge, crtc, encoder and connector.
- Fix endianness handling in various format conversion helpers.
- Make tests pass on big-endian platforms, and add test for rgb888 -> rgb565
- Move DRM_PLANE_HELPER_NO_SCALING to atomic helpers and rename, so
drm_plane_helper is no longer needed in most drivers.
- Use idr_init_base instead of idr_init.
- Rename FB and GEM CMA helpers to DMA helpers.
- Rework XRGB8888 related conversion helpers, and add drm_fb_blit() that
takes a iosys_map. Make drm_fb_memcpy take an iosys_map too.
- Move edid luminance calculation to core, and use it in i915.
Driver Changes:
- bridge/{adv7511,ti-sn65dsi86,parade-ps8640}, panel/{simple,nt35510,tc358767},
nouveau, sun4i, mipi-dsi, mgag200, bochs, arm, komeda, vmwgfx, pl111:
Assorted small fixes and doc updates.
- vc4: Rework hdmi power up, and depend on PM.
- panel/simple: Add Samsung LTL101AL01.
- ingenic: Add JZ4760(B) support, avoid a modeset when sharpness property
is unchanged, and use the new PM ops.
- Revert some amdgpu commits that cause garbaged graphics when starting
X, and reapply them with the real problem fixed.
- Completely rework vc4 init to use managed helpers.
- Rename via_drv to via_dri1, and move all stuff there only used by the
dri1 implementation in preperation for atomic modeset.
- Use regmap bulk write in ssd130x.

Just move the HAS_FLAT_CCS() check into needs_ccs_pages. This also then
fixes i915_ttm_memcpy_allowed() which was incorrectly reporting true on
DG1, even though it doesn't have small-BAR or flat-CCS.

Whenever we are not able to get enough timeslots
for required PBN, let's try to allocate those
using DSC, just same way as we do for SST.
v2: Removed intel_dp_mst_dsc_compute_config and refactored
intel_dp_dsc_compute_config to support timeslots as a
parameter(Ville Syrjälä)
v3: - Rebased
- Added a debug to see that we at least try reserving
VCPI slots using DSC, because currently its not visible
from the logs, thus making debugging more tricky.
- Moved timeslots to numerator, where it should be.
v4: - Call drm_dp_mst_atomic_check already during link
config computation, because we need to know already
by this moment if uncompressed amount of VCPI slots
needed can fit, otherwise we need to use DSC.
(thanks to Vinod Govindapillai for pointing this out)
v5: - Put pipe_config->bigjoiner_pipes back to original
condition in intel_dp_dsc_compute_config
(don't remember when I lost it)
v6: - Removed unnecessary drm_dp_mst_atomic_check as it is
now always called in a newly introduced
intel_dp_mst_find_vcpi_slots_for_bpp function

We would be using almost same code to loop through bpps while calling
drm_dp_atomic_find_vcpi_slots - lets remove this duplication by
introducing a new function intel_dp_mst_find_vcpi_slots_for_bpp
v2: Fix pbn_div calculation - shouldn't matter if its DSC or not.

We currently always exit that bpp loop because
drm_dp_atomic_find_vcpi_slots doesn't care if we actually
can fit those or not.
I think that wasn't the initial intention here, especially when
we keep trying with lower bpps, we are supposed to keep trying
until we actually find some _working_ configuration, which isn't the
case here.
So added that drm_dp_mst_check here, so that we can make sure
that try all the bpps before we fail.
