[PATCH v1 0/3] Add PLL clocks driver for StarFive JH7110

[Xingyu Wu]

This patch serises are to add PLL clocks driver and modify
the system clock driver to depend on PLL clocks driver for the 
StarFive JH7110 RISC-V SoC.

PLL are high speed, low jitter frequency synthesizers in JH7110.
Each PLL clocks work in integer mode or fraction mode by some dividers,
and the dividers are set in several syscon registers.
The formula for calculating frequency is: 
Fvco = Fref * (NI + NF) / M / Q1

The first patch adds docunmentation to describe PLL clock bindings,
and the second patch adds driver to support PLL clocks for JH7110 and 
modifies the system clock driver.

This patchset should be applied after this patchset about JH71x0 clock
