From 9da66539281b5e15afc4a4739014c8923059d894 Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Sun, 13 Dec 2009 22:29:47 +0100 Subject: [PATCH] mfd: Add twl6030 regulator subdevices This patch adds initial support for creating twl6030 PMIC specific voltage regulators in the twl mfd driver. Board specific regulator configurations will have to be passed from respective board files.
