From 24f668debcd9fe774668920c4b8152fab0b5732a Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Fri, 17 Jun 2016 16:21:05 +0530 Subject: [PATCH] clk: Combine DT binding doc for max77686 and max77802 The clock IP used on the Maxim PMICs max77686 and max77802 are same. The configuration of clock register is also same except the number of clocks. Define the common DT binding file for the clocks of Maxim PMICs MAX77686 and MAX77802. For this, remove the separate DT binding document file for maxim,max77802 and move all information to maxim,max77686 DT binding document.
