Surely some sort of Arm specific mailing list should be added here ? 
platform-drivers-x86 for arm64 platform drivers standalone, makes little 
sense.

Perhaps for each new SoC class added - you could add the appropriate 
mailing list linux-arm-msm is suspiciously missing from the list even 
though the only driver that will live in this directory after this 
series is a qcom based device.

And if tomorrow someone added a Rockchip based EC controller then you'd 
assume the rockchip mailing list should get a ping.
