ARM sp804 Dual Timers | ||
--------------------------------------- | ||
|
||
Required properties: | ||
- compatible: Should be "arm,sp804" & "arm,primecell" | ||
- interrupts: Should contain the list of Dual Timer interrupts. This is the | ||
interrupt for timer 1 and timer 2. In the case of a single entry, it is | ||
the combined interrupt or if "arm,sp804-has-irq" is present that | ||
specifies which timer interrupt is connected. | ||
- reg: Should contain location and length for dual timer register. | ||
- clocks: clocks driving the dual timer hardware. This list should be 1 or 3 | ||
clocks. With 3 clocks, the order is timer0 clock, timer1 clock, | ||
apb_pclk. A single clock can also be specified if the same clock is | ||
used for all clock inputs. | ||
|
||
Optional properties: | ||
- arm,sp804-has-irq = <#>: In the case of only 1 timer irq line connected, this | ||
specifies if the irq connection is for timer 1 or timer 2. A value of 1 | ||
or 2 should be used. | ||
|
||
Example: | ||
|
||
timer0: timer@fc800000 { | ||
compatible = "arm,sp804", "arm,primecell"; | ||
reg = <0xfc800000 0x1000>; | ||
interrupts = <0 0 4>, <0 1 4>; | ||
clocks = <&timclk1 &timclk2 &pclk>; | ||
clock-names = "timer1", "timer2", "apb_pclk"; | ||
}; |
