Date: Thu, 14 Jun 2012 13:55:25 +0800 From: Axel Lin <axel.lin@...il.com> To: linux-kernel@...r.kernel.org Cc: Anuj Aggarwal <anuj.aggarwal@...com>, Mark Brown <broonie@...nsource.wolfsonmicro.com>, Liam Girdwood <lrg@...com> Subject: [PATCH] regulator: tps65023: Fix mask for LDOs output voltage select control According to the datasheet: The LDO_CTRL registers are used to set the output voltage of LDO1 and LDO2. LDO_CTRL[7] and LDO_CTRL[3] are reserved and should always be written to 0. Thus the mask for TPS65023_LDO_1 and TPS65023_LDO_2 should be 0x07 and 0x70 respectively.
