[PATCH V2] ARM: dts: exynos5250-arndale: Add PMIC node entry

Amit Daniel Kachhap amit.daniel at samsung.com
Mon Feb 11 11:36:24 EST 2013


Added S5M8767 PMIC DT nodes for Arndale board. Only the used
LDO's/BUCK are defined here. Also the nodes describe the default/reset
state LDO's and no power mangement tuning is implemented. The usage
desription can be found in s5m8767 device tree binding documentation.

This patch is based on Samsung kernel maintainer's for-next tree.
git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git for-next

The s5m8767 DT support is already accepted by regulator's maintainer and is
present in the tree,
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-next

Changes since V1:
* Removed un-necessary status field settings.
* Added entries for LDO's 22,23,25,26 and BUCK9
