Hello, I hope that this is the correct place to post. I have a few questions about the Also SoC development. I am trying to write a driver for ASoC that will connect an S3C2410 cpu to an AK4550 codec via an I2S bus. The AK4550 codec appears to be completely unconfigurable, with no onboard registers (if I am wrong on this, please let me know. All the data sheets I have show no registers, which I find 'interesting'). All that should be required to get output from the codec is to power the module and send audio data via the I2S bus. To this end I've started with the ./s3c24xx/smdk2440.c file and ripped all the I2C control stuff out, and added code that powers the module via machine-specific GPIOs. On the codec side I've started with the AK4535, and pulled out almost everything interesting. The AK4550 has two input pins which control a de-emphasis filter for when the codec does ADC conversions, but I don't really know what to do with them. On to the questions: 1) Is the AK4550 codec really without registers like I think it is? 2) What is the best way to hook up the de-emphasis pins and expose them? I feel like I need generic functions in the codec to control them, and those generics should somehow hook to machine-specific functions. I don't know how to do this. 3) Am I basically on the right track here? 4) Does ASoC have a canonical repository that I should be pulling the latest code from? 5) Does ASoC have its own mailing list/IRC channel?
