I have to develop a driver for a custom board based on the at91sam9260
with a PCM1808/TAS5709 chipset combo. I am addressing the PCM1808 first
because it is a simpler device. Since I'm new to ASoC I'm looking for
some help in this list on how to go about writing this driver.
So far I have identified two files that I need to work on (other than
the needed kconfig modifications). First is the codec driver at
sound/soc/codecs/PCM1808.[c|h] which is based on the existent pcm3008
driver; I believe I'm fine with this.
The second file is the machine driver at sound/soc/atmel/myBoard.c. I'm
using sam9g20_wm8731.c as reference, on which I believe I found a typo
which I reported in a separated e-mail.
So my first question is, is this two-files step the right approach? am I
in the right track? I'm using the 2.6.30 kernel.
Other questions will come and I hope I will get some cycles from you to
help me direct my work. Of course I'll be glad to submit my driver work
for inclusion in the kernel if it proves useful.
