Vendor: Silicon Laboratories

Description

Silicon Labs HFRCODPLL peripheral (high-frequency RC oscillator with digital phase-locked loop).
Can be used as a free-running RC oscillator or with PLL lock to the crystal oscillators HFXO
or LFXO. To enable PLL, set the `clocks` property to the source crystal oscillator, and set
the `dpll-*` options to desired values.

In PLL mode, `clock-frequency` represents the target PLL frequency.
In free-running mode, `clock-frequency` represents the HFRCO band to use.
