Jerome, I have reworked my driver reusing axg-audio code as most as I
could and now I have one more question. Lets see on this definition from
axg-audio:
#define AUD_MST_MUX(_name, _reg, _flag) \
AUD_MUX(_name##_sel, _reg, 0x7, 24, _flag, \
mst_mux_parent_data, 0)
#define AUD_MST_MCLK_MUX(_name, _reg) \
AUD_MST_MUX(_name, _reg, CLK_MUX_ROUND_CLOSEST)
CLK_SET_RATE_PARENT is not set here. But why? It means, that topmost pll
clock will not be reconfigured at runtime to satisfy the rate that was
requested from axg-tdm.
