You might just update this changelog to clarify why you're using the the
driver-specific prepare & complete terminology whereas this code is
using begin/finish hooks as part of platform_pm_ops.
IOW, state that this will soon be becoming a real driver, so you're
using the driver terminology.
Also note that subject uses prepare & finish instead of prepare & complete.
