		* Pistachio general-purpose timer based clocksource

		Required properties:
		- compatible: "img,pistachio-gptimer".
		- reg: Address range of the timer registers.
		- interrupts: An interrupt for each of the four timers
		- clocks: Should contain a clock specifier for each entry in clock-names
		- clock-names: Should contain the following entries:
		"sys", interface clock
		"slow", slow counter clock
		"fast", fast counter clock
		- img,cr-periph: Must contain a phandle to the peripheral control
		syscon node.

		Example:
		timer: timer@18102000 {
		compatible = "img,pistachio-gptimer";
		reg = <0x18102000 0x100>;
		interrupts = <GIC_SHARED 60 IRQ_TYPE_LEVEL_HIGH>,
		<GIC_SHARED 61 IRQ_TYPE_LEVEL_HIGH>,
		<GIC_SHARED 62 IRQ_TYPE_LEVEL_HIGH>,
		<GIC_SHARED 63 IRQ_TYPE_LEVEL_HIGH>;
		clocks = <&clk_periph PERIPH_CLK_COUNTER_FAST>,
		<&clk_periph PERIPH_CLK_COUNTER_SLOW>,
		<&cr_periph SYS_CLK_TIMER>;
		clock-names = "fast", "slow", "sys";
		img,cr-periph = <&cr_periph>;
		};
