Subject: [PATCH 1/2] ASoC: sgtl5000: Fix define for SGTL5000_BIAS_R_MASK
Date: Wed, 19 Oct 2011 10:54:56 +0800 [thread overview]
Message-ID: <1318992896.7128.1.camel@phoenix> (raw)
According to the datasheet:
CHIP_MIC_CTRL 0x002A
BITS[9:8] BIAS_RESISTOR
0x0 = Powerd off
0x1 = 2.0 kohm
0x2 = 4.0 kohm
0x3 = 8.0 kohm
Thus SGTL5000_BIAS_R_MASK should be defined as 0x0300 instead of 0x0200.
