* 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@18102000 {
|
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>;
|
};
