     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";
            };
