From 8d561b60a9174defff2e48e109f68a5f2ae7dd9c Mon Sep 17 00:00:00 2001 From: J Keerthy Date: Thu, 6 Jun 2013 10:57:21 +0530 Subject: mfd: DT bindings for the palmas family MFD Add the various binding files for the palmas family of chips. There is a top level MFD binding then a seperate binding for regulators IP blocks on chips.
