I've merged them into next/drivers now, sorry for the delay.

Just one question that came in another thread, about the interface when
the reset controllers are disabled: You return ERR_PTR(-ENOSYS)
from reset_control_get_optional() here, and WARN_ON() any functions
called later. Are you sure this is the best interface? We have other
subsystems that just return a NULL pointer in this case so it doesn't
trigger IS_ERR(), and then you can pass the NULL pointer into the
other functions without causing an error message.
