 Required properties ("st,sti-uni-player" compatibility only):
   - clocks: CPU_DAI IP clock source, listed in the same order than the

 Optional properties:
   - pinctrl-0: defined for CPU_DAI at 1 and CPU_DAI at 4 to describe I2S PIOs for

   - pinctrl-names: should contain only one value - "default".
