  STM32F411 PLL I2S.

  Fully configurable I2S dedicated PLL.

  1 output clocks supported, the frequency can be computed with the following formula:

    f(PLLI2S_R) = f(VCO clock) / PLLI2S R  --> PLLI2S

      with f(VCO clock) = f(PLL I2S clock input) × (PLLI2S N / PLLI2S M)


compatible: "st,stm32f411-plli2s-clock"
