[PATCH 0/4] cpsw: support for control module register

In order to make the cpsw driver work in for example RMII mode with
external clock the driver needs to learn about the control module
register that is at least available on AM33xx SoCs. I'm not sure
whether other chips have similar or compatible bits in such a register,
hence I limited the code paths to that familiy only.
This series is necessary to make the cpsw driver work after resume on
my systems, because that control register is only written from the
bootloader at startup, and its content is altered after resume, so it
needs reprogramming.
The first patch is actually just a cleanup to make the additional
memory resource handling cleaner.
Patches 1-3 are for the net tree and apply to net-next. Patch 4/4 is
for the ARM/dts tree, but can be merged independently.
Thanks,
Daniel
