0001 * Pistachio general-purpose timer based clocksource
0002
0003 Required properties:
0004 - compatible: "img,pistachio-gptimer".
0005 - reg: Address range of the timer registers.
0006 - interrupts: An interrupt for each of the four timers
0007 - clocks: Should contain a clock specifier for each entry in clock-names
0008 - clock-names: Should contain the following entries:
0009 "sys", interface clock
0010 "slow", slow counter clock
0011 "fast", fast counter clock
0012 - img,cr-periph: Must contain a phandle to the peripheral control
0013 syscon node.

0015 Example:
0016 timer: timer@18102000 {
0017 compatible = "img,pistachio-gptimer";
0018 reg = <0x18102000 0x100>;
0019 interrupts = <GIC_SHARED 60 IRQ_TYPE_LEVEL_HIGH>,
0020 <GIC_SHARED 61 IRQ_TYPE_LEVEL_HIGH>,
0021 <GIC_SHARED 62 IRQ_TYPE_LEVEL_HIGH>,
0022 <GIC_SHARED 63 IRQ_TYPE_LEVEL_HIGH>;
0023 clocks = <&clk_periph PERIPH_CLK_COUNTER_FAST>,
0024 <&clk_periph PERIPH_CLK_COUNTER_SLOW>,
0025 <&cr_periph SYS_CLK_TIMER>;
0026 clock-names = "fast", "slow", "sys";
0027 img,cr-periph = <&cr_periph>;
