In the process of porting some boards to DT, I noticed the simple-card driver is already capable of handling most cases just fine. The missing bits I've spotted are:
* The clock that is passed in is only read, never set, which is not sufficient for boards that support several sampling rates with different base frequencies
* The sysclk id that is passed to snd_soc_dai_set_sysclk() is hard-coded
* There's currently no support for calling into snd_soc_dai_set_clkdiv()
The following three patches fix all those and make simple-card a good match for the board I'm working with.
Thanks, Daniel
