1* Pistachio general-purpose timer based clocksource 2 3Required 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. 14 15Example: 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>; 28 }; 29
