st,stm32f4-plli2s-clock

Vendor: STMicroelectronics N.V.

Description

STM32F4 PLL I2S node binding:

Takes same input as Main PLL. PLLM factor and PLL source are common with Main PLL

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

  f(PLL_R) = f(VCO clock) / PLLR  --> PLLI2S

    with f(VCO clock) = f(PLL clock input) × (PLLNI2S / PLLM)
