Subject: [PATCH 1/2] ASoC: wm8741: Fix setting interface format for DSP modes
Date: Mon, 17 Oct 2011 20:14:56 +0800 [thread overview]
Message-ID: <1318853696.4642.1.camel@phoenix> (raw)
According to the datasheet:
Format Control (05h)
BITS[3:2]
FMT[1:0] Audio data format selection
00 = right justified mode
01 = left justified mode
10 = I2S mode
11 = DSP mode
BIT[4] LRP Polarity selec for LRCLK/DSP mode select
0 = normal LRCLK poalrity/DSP mode A
1 = inverted LRCLK poarity/DSP mode B
For SND_SOC_DAIFMT_DSP_A, we should set 0x000C instead of 0x0003.
For SND_SOC_DAIFMT_DSP_B, we should set 0x001C instead of 0x0013.
