Subject: [PATCH] regulator: wm8400: Simplify set REGULATOR_MODE_IDLE mode in wm8400_dcdc_set_mode
Date: Wed, 01 Aug 2012 09:15:11 +0800 [thread overview]
Message-ID: <1343783711.8776.1.camel@phoenix> (raw)
To set REGULATOR_MODE_IDLE mode, what we do is to clear DC1_ACTIVE and
DC1_SLEEP bits, this can be done in one wm8400_set_bits() call.
