From d1cf4f65e1eb17bc8768d822755780588e42cf37 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Mon, 2 Apr 2012 18:19:28 +0800 Subject: regulator: Add support for tps62362 and tps62363 in tps62360-regulator driver According to the datasheet[1], tps62360 is register compatible with tps62362. tps62361B is register compatible with tps62363. Thus this patch adds support for tps62362 and tps62363.
