Adding a nice proc interface to read codec registers will be a nice feature have, like we have in generic ac97 registers, i added that that in wm9713.c by using ac97_proc.c

Liam,
Thank you for your support, my work is almost complete now, driver is working perfectly now.
I have one suggestion,
I modified the wm9713.c codec driver in probe function , so that
if(socdev->machine->dai_link->cpu_dai->private_data) codec->ac97->bus->private_data =socdev->machine->dai_link->cpu_dai->private_data;
Here i am assigning the controller private data.
so that my following ac97 read and write to access codec registers become good.
static void aaci_ac97_write(struct snd_ac97 *ac97, unsigned short reg, unsigned short val) { struct platform_controller *controller = ac97->bus->private_data; struct aaci *aaci = (struct aaci *)controller->bus_controller;
static unsigned short aaci_ac97_read(struct snd_ac97 *ac97, unsigned short reg) { struct platform_controller *controller = ac97->bus->private_data; struct aaci *aaci = (struct aaci *)controller->bus_controller; u32 v;
Is there a way to accomodate this in existing ASoC design? Or a better way to do this?
