| 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"; | |
| }; |
