than not providing cleared VRAM. AM

This is a Generic MIPI-DSI / DPI(+SPI) dual stack panel driver.
Although the MIPI specifications define how to communicate with a panel
to display an image, some panels still require a panel-specific
initialization sequence to be sent.
While there are many dedicated drivers for such panels, they

Add CONFIG_DRM_HEADER_TEST to ensure drm headers are self-contained and
pass kernel-doc. And for starters, fix one header that this catches.

Two patches extracted from my deadline scheduler RFC. I think they are making
the entity selection logic a bit easier on the eyes but as opinions may vary
please have a look and see what you think.

Retimers in H/w usually takes 30 to 40ms to wake up all the devices. To
get this we use the Extended Wake Time feature in which the sink device
tells us the minimum amount of time it requires to wake up and we need
to do a write to grant this request else we need to wake up within 1ms

vmwgfx had a number of cursor issues that related both to our handling
of dumb buffers and general detection when a cursor has actually changed.
Fix those issues and bump the kernel module version to allow userspace
to recognize fixed versions of the driver.

drm/vmwgfx: Refactor
This series adds DT-bindings and panel-simple implementation for the
DataImage FG080016DNCWAG03 8" 640x480 TFT LCD panel.
The timings are sourced from the FG080016DNCWAGL1 datasheet but
available for testing was only the DataImage FG080016DNCWAG03, for which
I can confirm these values work.

Patch 1 reverts a previous fix for loss of HDMI sync when playing YUV420
@ 59.94 media. The patch does resolve a calculation issue. It also makes
all fractional rates invalid which is a bigger problem.
Patch 2 provides a proper fix after I figured out the actual root cause
of the original problem.
This series adds the following fixes related to the virtual planes code
changes:
1) Initialize the return value of dpu_assign_plane_resources() so that
the function doesn't return a garbage value if all planes are
disabled/otherwise not visible.
2) Remove extraneous return value for dpu_crtc
With this user can hint low latency during exec queue creation.
KMD will forward hint to guc.
Note : There is some issue going on with GUC, that setting hint is not
correctly fixing high frequency. The work to fix that in GUC is
being done parallely so sending RFC to get KMD reviews going.

Hi,
this fixes two dtbs_check warnings by moving the video muxing node out of gpr
and adding a new imx7 specific DSI compatible to DT schema.
Best regards,
Alexander
