Need to provide CLKOUT0 to MCLK of audio codec TVL320AIC3101 with 24 MHz.

Specifications:

Hardware: TI tms320dm365

Software: Linux kernel 2.6.32.17

Audio Codec: TVL320AIC3101.

For that changed PINMUX4 register with enabling 21-20 bit with value '1' to enable CLKOUT0.

Also made hardware connection from processor to MCLK as per schematic.

Now to make it work what extra things need to change ?

Please suggest extra changes for kernel files,audio codec file and others if any.

Thanks.

CODEC file -> sound/soc/codecs/tlv320aic3x.c
Driver file -> sound/soc/davinci/

To provide CLKOUT0 to MCLK of Audio Codec :

1. Set the pinmux for CLKOUT0 in pinmux4 register.

2. Enable clock PLL Controller Register. Set value of Register CKEN - Clock enable control AUXCLK with 0x3 value.
(That is disabled by default in kernel. This change is very important to get the clock out of CLKOUT0)

Thanks,
