[PATCH 0/3] SC7180 MDSS core reset
Posted by Konrad Dybcio 2 weeks, 5 days ago 
Add the missing reset for the display subsystem and wire it up, so that
drivers can consume it.

Compile-tested only.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

Thanks!

Tested-by: Val Packett <val@packett.cool> # sc7180-ecs-liva-qc710

Might be worth noting in the commit message that the real world issue 
this solves is that after probing the driver, the DPU would keep trying 
to access the physical address that belonged to the EFI framebuffer, 
causing constant IOMMU faults and visual glitches on the display output.

P.S. what a coincidence that just a week ago this was discussed for 
sdm845
