The driver is basically working, but still incomplete and needs some tidy up before it will be accepted for mainline. I am posting the patches to get feedback from others as to how well it works on their boards and ideas to improve the code. The following issues still exist: - The setting of SDIV/LRDIV is ugly since it requires modifying one of the clock registers from the audio driver. - Audio capture has not been tested - Sometimes playback (ie aplay) results in noise. Killing the process and trying again will result in correct playback. - Some empty functions can probably be removed - Not sure if I2SONSSP/AC97 should be a function argument, or a Kconfig option (opinions please). ~Ryan -- Bluewater Systems Ltd - ARM Technology Solution Centre Ryan Mallon 5 Amuri Park, 404 Barbadoes St ryan at bluewatersys.com PO Box 13 889, Christchurch 8013 http://www.bluewatersys.com New Zealand Phone: +64 3 3779127 Freecall: Australia 1800 148 751 Fax: +64 3 3779135 USA 1800 261 2934
