You probably mean the BITCLK clock.
What is a bit pesky about this clock is that it can either be mastered by digital controller and the codec is a slave, or the other way around.
That's a bit surprising - I've never encountered a system that impelemnts this, it may be permitted by the spec but it's always the CODEC. The master clock from the CODEC is often provided by the SoC but I've not seen systems where anything other than the CODEC drives the actual AC'97 bus.
Ok, so let's assume a one direction. I'll have a look how I could add this clock to the probe() exactly as amba_probe() does.
It's not really adding anything though, it's just clumsy wording on their part - it's not like we need to distinguish this from analogue or any other type of AC'97 controllers.
Now if you prefer "ac97_controller" or something like that, that's as you wish, the name does not matter that much to me ;)
Yes.
Okay, let me add this to my todo list for v2. I already have suspend/resume/pm_suspend/pm_resume.
Cheers.
