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. | |
14 | ||
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>; | |
28 | }; |
