[PATCH V3 1/4] ARM: tegra: Add header file for pinctrl constants

From: Laxman Dewangan
Date: Thu Dec 05 2013 - 05:47:59 EST


This new header file defines pincontrol constants for Tegra to
use from Tegra's DTS file for pincontrol properties option.

Changes from V1:
- Get rid of lots of macro and converge it to TEGRA_PIN_ENABLE/DISABLE.
- Change macro name for PULL UP/DOWN/NONE.

Changes from V2:
- Convert TEGRA -> Tegra.
- Add comment on ENABLE/DSIABLE and remove from pulls.
