I am not sure whether now we can control read/writes to pad_mux from any driver
interface and I think we have to go through mux framework for any
read/writes to mux.

Sure, the drivers should not mess with those registers directly.

with this I cant control pad wake up capabilities with sysfs as done
earlier in serial.c
now control to read/write to pad is outside scope of the driver
interface as omap_hwmod_mux
is the one that takes decision for driver with mux values provided
during omap_hwmod_mux_init.

The sysfs interface to control this should still be from the drivers.
Sounds like we need some way to set the wakeup flags before pm_runtime_put
is called.
