cf8698df3a drm/nouveau: Remove support for legacy contexts/buffers 
Remove nouveau's support for legacy contexts and buffers. It was
required by libdrm earlier than 2.4.33, released in March 2012. A
previous attempt in 2013 to remove the functionality [1] had to be
reverted [2] as there were still users left. Libdrm 2.4.33 is now
almost 11 years old and it is time for userspace to move on.

With the nouveau code gone, we can also remove the driver-feature
bit DRIVER_KMS_LEGACY_CONTEXT.

6e41acd2e5 drm/vkms: reintroduce prepare_fb and cleanup_fb functions 
With commit 359c6649cd ("drm/gem: Implement shadow-plane {begin,
end}_fb_access with vmap"), the behavior of the shadow-plane helpers
changed and the vunmap is now performed at the end of
the current pageflip, instead of the end of the following pageflip.

By performing the vunmap at the end of the current pageflip, invalid
memory is accessed by the vkms during the plane composition, as the data
is being unmapped before being used, as reported by the following
warning:

c9ba134e05 drm/debugfs: use octal permissions instead of symbolic permissions 
Currently, debugfs functions are using symbolic macros as permission
bits, but checkpatch reinforces permission bits in the octal form, as
they are more readable and easier to understand [1]. Moreover, using
the symbolic macro S_IFREG is redundant.

Therefore, use octal permission bits in all debugfs functions.

6d6defd421 drm/mxsfb: improve clk handling for axi clk 
Ignoring errors from devm_clk_get() is wrong. To handle not all platforms
having an axi clk use devm_clk_get_optional() instead and do proper error
handling.

Also the clk API handles NULL as a dummy clk (which is also returned by
devm_clk_get_optional() if there is no clk) so there is no need to check
for NULL before calling clk_prepare_enable() or its counter part.

Add support for the 1080x2400 Visionox VTDR6130 AMOLED DSI panel
found on the Qualcomm SM8550 MTP board.

By default the the panel is configured to work with DSI compressed
streams, but can work in uncompressed video mode since 1080x2400 in
RGB888 fits in the 4 DSI lanes bandwidth.

While display compression is preferred for performance and power
reasons, let's start with the uncompressed video mode support and
add the DSC support later on.

273c417658 drm/vc4: crtc: Fix timings for VEC modes 
This commit fixes vertical timings of the VEC (composite output) modes
to accurately represent the 525-line ("NTSC") and 625-line ("PAL") ITU-R
standards.

Previous timings were actually defined as 502 and 601 lines, resulting
in non-standard 62.69 Hz and 52 Hz signals being generated,
respectively.

Changes to vc4_crtc.c have also been made, to make the PixelValve
vertical timings accurately correspond to the DRM modeline in interlaced
modes. The resulting VERTA/VERTB register values have been verified
against the reference values set by the Raspberry Pi firmware.
