st,stm32f411-plli2s-clock

Vendor: STMicroelectronics

Description

STM32F411 PLL I2S node binding:

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)
