+* 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>;
+	};
