1ARM sp804 Dual Timers
2---------------------------------------
3
4Required properties:
5- compatible: Should be "arm,sp804" & "arm,primecell"
6- interrupts: Should contain the list of Dual Timer interrupts. This is the
7	interrupt for timer 1 and timer 2. In the case of a single entry, it is
8	the combined interrupt or if "arm,sp804-has-irq" is present that
9	specifies which timer interrupt is connected.
10- reg: Should contain location and length for dual timer register.
11- clocks: clocks driving the dual timer hardware. This list should be 1 or 3
12	clocks.	With 3 clocks, the order is timer0 clock, timer1 clock,
13	apb_pclk. A single clock can also be specified if the same clock is
14	used for all clock inputs.
15
16Optional properties:
17- arm,sp804-has-irq = <#>: In the case of only 1 timer irq line connected, this
18	specifies if the irq connection is for timer 1 or timer 2. A value of 1
19	or 2 should be used.

21Example:
22
23	timer0: timer@fc800000 {
24		compatible = "arm,sp804", "arm,primecell";
25		reg = <0xfc800000 0x1000>;
26		interrupts = <0 0 4>, <0 1 4>;
27		clocks = <&timclk1 &timclk2 &pclk>;
28		clock-names = "timer1", "timer2", "apb_pclk";
29	};
