mailbox: qcom: Create APCS child device for clock controller (c815d769) · Commits · 戴 / test

There is a clock controller functionality provided by the APCS hardware block of msm8916 devices. The device-tree would represent an APCS node with both mailbox and clock provider properties. Create a platform child device for the clock controller functionality so the driver can probe and use APCS as parent. Signed-off-by:
