[PATCH 0/2] Add pinctrl support to AM33XX family of devices

Adds pinctrl support to AM33XX family of devices. This patch is
based on the pinctrl-simple driver submitted by Tony L
here: http://lwn.net/Articles/496075/

These patches were tested on AM335x-Bone and AM335x-EVM

You might want to update to the latest version, which is now called
pinctrl-single instead of pinctrl-simple. Should be easy to update,
note that we're still waiting on people to comment on the binding,
so you might want to wait a bit before reposting so we have the
driver merged.

Hi Tony,

Thanks for reviewing.

In that case, I will submit the patches with respect to pinctrl-single
after it is available in linux-next tree.

Thanks
