From: Thomas Abraham Date: Fri, 23 Nov 2012 08:03:13 +0000 (+0530) Subject: regulator: max8997: reorder buck1/2/5 dvs setup code X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=11ec7bf001e7bfd37f244042032e15dac2c301bc;p=linux-beck.git regulator: max8997: reorder buck1/2/5 dvs setup code The BUCKxDVSx register programming is now moved prior to setting up of the gpio based dvs mode. This will ensure that all the BUCKxDVSx registers are programmed with appropriate voltage values before the gpio based dvs mode is selected for buck1/2/5.
