Add dma-coherent property to fastRPC context bank nodes to pass dma
sequence test in fastrpc sanity test, ensure that data integrity is
maintained during DMA operations.

This wasn't ever tested:

sm8650-qrd.dtb: remoteproc@32300000: glink-edge:fastrpc:compute-cb@1:
'dma-coherent' does not match any of the regexes: 'pinctrl-[0-9]+'

Ling,
How is this testing-patches-before-sending work in different teams? Do
you have such requirement?


Best regards,
Krzysztof

No clue if the original DTS change should be reverted or these are in
fact DMA coherent, but let's choose one path...

Hi Krzysztof,
Add dma-coherent: true in this file: Documentation/devicetree/bindings/misc/qcom,fastrpc.yaml at line number 89 can pass the DTcheck.

I don't understand your comment. Did you read the link above?

Anyway, I was asking: are you testing the patches before sending?

Best regards,
Krzysztof

Yes, I tested before sending.

Then I am confused why there is a warning. If this was tested and sent,
it means you sent code with a known warning.

Best regards,
Krzysztof
