Merge v7.1-rc5 into drm-next

2026-05-28T07:58:36+00:00

Boris Brezillion needs the gem lru fixes 379e8f1ca5e9 ("drm/gem: Make
the GEM LRU lock part of drm_device") backmerged for drm-misc-next.
That also means we need to sort out the rename conflict in panthor with
the fixup patch from Boris from drm-tip.

drm/msm/dsi: don't dump registers past the mapped region

2026-05-13T13:18:35+00:00

On DSI 6G platforms the IO address space is internally adjusted by
io_offset. Later this adjusted address might be used for memory dumping.
However the size that is used for memory dumping isn't adjusted to
account for the io_offset, leading to the potential access to the
unmapped region. Lower ctrl_size by the io_offset value to prevent
access past the mapped area.

drm/msm/dsi: Add support for RGB101010 pixel format

2026-03-25T12:06:10+00:00

Add video and command mode destination format mappings for RGB101010,
and extend the VID_CFG0 DST_FORMAT bitfield to 3 bits to accommodate
the new format value.

Make sure this is guarded behind MSM_DSI_6G_VER >= V2.1.0 as anything
older does not support this.

Required for 10 bit panels such as the BOE BF068MWM-TD0 found on the
Nothing Phone (3a).

drm/msm/dsi: rename MSM8998 DSI version from V2_2_0 to V2_0_0

2026-03-25T12:06:10+00:00

The MSM8998 DSI controller is v2.0.0 as stated in commit 7b8c9e203039
("drm/msm/dsi: Add support for MSM8998 DSI controller"). The value was
always correct just the name was wrong.

Rename and reorder to maintain version sorting.

mipi_dsi_pixel_format_to_bpp return dst bpp not src bpp, dst bpp may
not be the uncompressed data size. use src bpc * 3 to get src bpp,
this aligns with pclk rate calculation.
