+* 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@...02000 {
+ 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>;
+ };
