Subject: [PATCH 2/2] regulator: wm8400: Use regulator_map_voltage_linear for wm8400_dcdc_ops
Date: Thu, 31 May 2012 17:40:22 +0800 [thread overview]
Message-ID: <1338457222.4165.2.camel@phoenix> (raw)
In-Reply-To: <1338457140.4165.1.camel@phoenix>
wm8400_dcdc_ops uses simple linear voltage maps.
Thus use regulator_map_voltage_linear is more efficient than using the default
regulator_map_voltage_iterate.
