This is specifically needed on recent Qualcomm platforms like SC8280XP. Reviewed-by: Rob Herring Reviewed-by: Bjorn Andersson Signed-off-by: Johan Hovold --- James and Martin, I'm resending as reminder in case you missed the first submission which included an arm64 dts update and also did not have you on CC as I was following scripts/get_maintainer.pl too literally: https://lore.kernel.org/all/20221205100837.29212-1-johan+linaro@kernel.org/ I've added Rob and Bjorn's Reviewed-by tags from the above thread. Could you take this one through the scsi tree?
