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. --- bod
