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

2026-03-25T12:06:10Z

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

2026-03-25T12:06:10Z

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.

drm/msm: add missing MODULE_DEVICE_ID definitions

2026-03-25T06:06:03Z

The drm/msm module bundles several drivers, each of them having a separate OF match table, however only MDSS (subsystem), KMS devices and GPU have corresponding MODULE_DEVICE_ID tables. Add MODULE_DEVICE_ID to the display-related driver and to all other drivers in this module, simplifying userspace job.

The quirk flag DSI_PHY_7NM_QUIRK_PRE_V4_1 is renamed to DSI_PHY_7NM_QUIRK_V4_0 to better reflect the actual hardware revision it applies to. (Only SM8150 uses it, its hardware revision is 4.0) No functional change.

drm/msm/dsi: fix pclk rate calculation for bonded dsi

2026-03-06T18:41:08Z

Recently, we round up new_hdisplay once at most, for bonded dsi, we may need twice, since they are independent links, we should round up each half separately. This also aligns with the hdisplay we program later in dsi_timing_setup() Example: full_hdisplay = 1904, dsc_bpp = 8, bpc = 8 new_full_hdisplay = DIV_ROUND_UP(1904 * 8, 8 * 3) = 635 if we use half display new_half_hdisplay = DIV_ROUND_UP(952 * 8, 8 * 3) = 318 new_full_display = 636 Fixes: 7c9e4a554d4a ("drm/msm/dsi: Reduce pclk rate for compression") Signed-off-by: Pengyu Luo Reviewed-by: Dmitry Baryshkov Patchwork: https://patchwork.freedesktop.org/patch/709716/ Link: https://lore.kernel.org/r/20260306163255.215456-1-mitltlatltl@gmail.com Signed-off-by: Dmitry Baryshkov
