From 02dac70a5cef767ce50b648b457781b5d000b507 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Wed, 24 Apr 2013 11:51:12 +0800 Subject: [PATCH] regulator: mc13892: Fix MC13892_SWITCHERS0_SWxHI bit in set_voltage_sel It is necessary to clear MC13892_SWITCHERS0_SWxHI bit when set voltage to the voltage range from 1100000 to 1375000. Leaving MC13892_SWITCHERS0_SWxHI bit untouched may result in wrong voltage setting. For example, currently switch voltage from 1400000 to 1300000 will set the voltage to 1800000 because the HI bit is still set.
