From 8c5e461df77c14254a408e792bb32ddf08213726 Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Thu, 5 Jul 2012 12:53:04 +0530 Subject: regulator: dt: add policy to have property "regulator-compatible" Add the policy for regulator DT such that if device have multiple regulator and its binding contains a child node that describes each regulator then each regulator child node must have the property "regulator-compatible" which matches with regulator name of their hardware counterparts. Modify the DT documentation of regulator devices to reflect this policy.
