1 * Pistachio general-purpose timer based clocksource
2
3 Required properties:
4 - compatible: "img,pistachio-gptimer".
5 - reg: Address range of the timer registers.
6 - interrupts: An interrupt for each of the four timers
7 - clocks: Should contain a clock specifier for each entry in clock-names
8 - clock-names: Should contain the following entries:
9 "sys", interface clock
10 "slow", slow counter clock
11 "fast", fast counter clock
12 - img,cr-periph: Must contain a phandle to the peripheral control
13 syscon node.

15 Example:
16 timer: timer@18102000 {
17 compatible = "img,pistachio-gptimer";
18 reg = <0x18102000 0x100>;
19 interrupts = <GIC_SHARED 60 IRQ_TYPE_LEVEL_HIGH>,
20 <GIC_SHARED 61 IRQ_TYPE_LEVEL_HIGH>,
21 <GIC_SHARED 62 IRQ_TYPE_LEVEL_HIGH>,
22 <GIC_SHARED 63 IRQ_TYPE_LEVEL_HIGH>;
23 clocks = <&clk_periph PERIPH_CLK_COUNTER_FAST>,
24 <&clk_periph PERIPH_CLK_COUNTER_SLOW>,
25 <&cr_periph SYS_CLK_TIMER>;
26 clock-names = "fast", "slow", "sys";
27 img,cr-periph = <&cr_periph>;
