3 Binding for keystone PLLs. The main PLL IP typically has a multiplier,
4 a divider and a post divider. The additional PLL IPs like ARMPLL, DDRPLL
5 and PAPLL are controlled by the memory mapped register where as the Main
6 PLL is controlled by a PLL controller registers along with memory mapped
9 This binding uses the common clock binding[1].

14 - #clock-cells : from common clock binding; shall be set to 0.
15 - compatible : shall be "ti,keystone,main-pll-clock" or "ti,keystone,pll-clock"
16 - clocks : parent clock phandle
17 - reg - pll control0 and pll multipler registers
18 - reg-names : control, multiplier and post-divider. The multiplier and
19 post-divider registers are applicable only for main pll clock
20 - fixed-postdiv : fixed post divider value. If absent, use clkod register bits
