The point Santosh is making here though is that any drivers tinkering with registers belonging to a separate hardware block is a recipe for a long term maintenance nightmare with mysterious bugs popping up as things are not clocked or powered properly or become racy with other drivers. Each hardware block needs to have it's own driver and then the drivers can communicate using some Linux generic APIs like clock, regulator, phy, or mailbox frameworks.
