im completely new to driver development.
how do i tell my (/linux/sound/pci/ice1712/ap192k.c) driver which gpio
pins connect to wat? i have all the wiring from ak4385 and ak4114 to the
envy24ht, as well as the data sheets, can someone point me in the
direction i have to take to get this driver working? and please for god
sake dont tell me to go and read, if u know the answer, dont be shy,
