DRM MSM fixes for 6.14

Hi Rob

Here is the list of fixes for this cycle:

1. More catalog fixes for the foll:

• to skip watchdog programming through top block if its not present
• fix the setting of WB mask to ensure the WB input control is programmed correctly through ping-pong
• drop lm_pair for sm6150 as that chipset does not have any 3dmerge block

2. Fix the mode validation logic for DP/eDP to account for widebus (2ppc) to allow high clock resolutions
3. Fix to disable dither during encoder disable as otherwise this was causing kms_writeback failure due to resource sharing between WB and DSI paths as DSI uses dither but WB does not
4. Fixes for virtual planes, namely to drop extraneous return and fix uninitialized variables
5. Fix to avoid spill-over of DSC encoder block bits when programming the bits-per-component
6. Fixes in the DSI PHY to protect against concurrent access of PHY_CMN_CLK_CFG regs between clock and display drivers

Thanks

Hi @robclark / @lumag

In this list of fixes, I have added "Cc: stable@vger.kernel.org" for below two fixes:

1. drm/msm/dpu: Disable dither in phys encoder cleanup
2. drm/msm/dp: account for widebus and yuv420 during mode validation

These two are quite important fixes in my opinion. Let me know your thoughts. For the others, I have kept only the fixes tags.

Thanks

Abhinav

Oh, I guess we crossed paths, I guess you now need to rebase since I pulled in a couple of fixes

• Could you please check with Bjorn, we might need to take bindings from https://patchwork.freedesktop.org/series/144579/ if he is going to pick up dts bits, even if they are not marked as fixes.
• https://patchwork.freedesktop.org/patch/636944/?series=144793&rev=1 should be good to go
