In linux kernel since version 5.1 (release Date: 2019-05-05)
Enable this to support the PLLs embedded into the Baikal-T1 SoC
System Controller. These are five PLLs placed at the root of the
clocks hierarchy, right after an external reference oscillator
(normally of 25MHz). They are used to generate high frequency
signals, which are either directly wired to the consumers (like
CPUs, DDR, etc.) or passed over the clock dividers to be only
then used as an individual reference clock of a target device.
