as per the discussion on v5 (https://patchwork.kernel.org/project/linux-arm-msm/patch/1628754078-29779-4-git-send-email-rajpat@xxxxxxxxxxxxxx/)
I remain unconvinced that configuring the CS pin both as CS and GPIO is a good idea.
If you think it is necessary in this case (maybe some kind of quirk?) please
provide a rationale.
