5   PLL node binding for STM32L4 and STM32L5 devices
7   It can be used to describe 3 different PLLs: PLL, PLLSAI1 and PLLSAI2.
8   Only main PLL is supported for now.
14   Each PLL can have up to 3 output clocks and for each output clock, the
17     f(PLL_P) = f(VCO clock) / PLLP  --> PLLSAI3CLK
18     f(PLL_Q) = f(VCO clock) / PLLQ  --> PLL48M1CLK
19     f(PLL_R) = f(VCO clock) / PLLR  --> PLLCLK (System Clock)
21       with f(VCO clock) = f(PLL clock input) × (PLLN / PLLM)
23   The PLL output frequency must not exceed 80 MHz.
