    Subject[PATCH 11/11] devtree: add binding documentation for sp804
    Date
    From: Haojian Zhuang <haojian.zhuang@linaro.org>

    The sp804 binding is already in use by several platforms. This adds missing
    documentation for the binding and also extends the binding to handle some
    additional possible interrupt configurations.

    +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";
    + };
