Here's McBSP patch on omap24xx
Any comments are welcome.
p.s., Yes there's TSC mux settings for future use.

Hi
This patch enable OMAP sound on omap24xx
To test omap sound, you first have to patch the first spi patch from komal
shah not the latest spi patch.
It also adds 'OSS L/R Channel Interchange fix' on tsc2101
Any comments are welcome.
Regards,
Kyungmin Park
P.S., There's some problem when running qtopia on H4.
At the end of mediaplay. we can't stop audio, exactly audio_sync why?
But madplay is working well :)
