Add the audio clock controller which is part of the audio bus This controller takes 8 input plls, and the usual clock gate, from the main clock controller. It provides for the all the devices of the audio subsystem, such as tdms, spdif, pdm, etc.
Signed-off-by: Jerome Brunet <[email protected]> --- Kevin, Please note that this change depends on the axg audio clock bindings [0]. It will be part of our PR to clock in this cycle. As usual, I've prepared a topic branch with the DT changes for you. Please, let me know when you need a tag on it.
