HI:
I am use wm8731 codec connect to BF537 sport0(I2S mode),and I use 2008R1_RC8 kernel
In linux-2.6.x/sound/soc/blackbin/,there is a bf5xx-wm8731.c
I use those souce code for my board,
and my connect is:
WM8731: BCLK --------- RSCLK0(TSCLK0) BF537
DACDAT ----- DT0PRI
ADCDAT----DR0PRI
DACLRC----TFS0
ADCLRC---RFS0
DOES this connection ok?
MY I2C----OK!
And when I send data to WM8731 I printk config of BF537 sport is
TCR1 ------0x4400
TCR2 ---------0xf
TCKDIV ------0x0
TFSDIV ------0x0
RCR1------- 0x4400
RCR2------- 0x20f
RCLDIV -------0x0

Thanks!
But the release version of 2008RC-RC8 support wm8731
Can you give me some suggestion about how to write this driver?
the ssm2602.c is ok?

as i said, that release did not support the wm8731. the driver in the release did not actually work.
the ssm2602 works fine and is supported. but it is not a wolfsom codec driver, it is for the ADI part.
