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";
|
||
|
|
};
