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. The patch 3 modifies the syscon dt-bindings and adds optional pateerProperties about PLL clock controller. The patch 4 modifies the SYSCRG dibindings and adds PLL clock inputs. The patch 5 modifies the system clock driver and changes PLL clock source from PLL clock controller instead of the fixed factor clocks. The last patch adds PLL clock node and modifies the syscrg node in dts file. This patchset should be applied after these patchset about JH7110 clock driver[1] and syscon dt-bindings[2].
