Provide the automatic configurable LRC and BCLK divide. The bit clock rate can be chosen by userspace. The driver will make configurations of LRCK and BCLK automatically when playback or capture in master mode.
As far as I can tell this only provides manual selection from userspace, I can't see the code for automatic selection. I'd not expect to see any userspace control of something like this, if there is an override I'd expect it to come from the machine driver, and as I've previously said I'd definitely expect automatic selection to be the default like it is with other CODEC drivers.
I see. Maybe I can get the bit clock and frame sync information when hardware parameter. According to the information to make LRC and BCLK divide confirguration.
