Subject: [PATCH] regulator: tps65023: Fix mask for LDOs output voltage select control
Date: Thu, 14 Jun 2012 13:55:25 +0800 [thread overview]
Message-ID: <1339653325.6769.1.camel@phoenix> (raw)
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.
