[PATCH v3 6/7] ARM: zynq: DT: Add pinctrl information

From: Soren Brinkmann
Date: Fri Dec 12 2014 - 11:38:04 EST

Add pinctrl descriptions to the zc702 and zc706 device trees.

Signed-off-by: Soren Brinkmann <soren.brinkmann@xxxxxxxxxx>
Tested-by: Andreas FÃrber <afaerber@xxxxxxx>
---
Changes since v1:
- remove 'pinctrl-' prefix for pinctrl sub-nodes
- separate config and mux nodes

Changes since RFC v2:
- add pinconf properties to zc702 mdio node
- remove arguments from bias-related props

Changes since RFC v1:
- separate DT changes into their own patch
