* Device tree bindings for Texas Instruments keystone pll controllerThe main pll controller used to drive theC66x CorePacs, the switch fabric,and a majority of the peripheral clocks (all but the ARM CorePacs, DDR3 andthe NETCP modules) requires a PLL Controller to manage the various clockdivisions, gating, and synchronization.Required properties:- compatible: "ti,keystone-pllctrl", "syscon"- reg: contains offset/length value for pll controller registers space.Example:pllctrl: pll-controller@0x02310000 { compatible = "ti,keystone-pllctrl", "syscon"; reg = <0x02310000 0x200>;};
