    Subject[PATCHv4 2/7] Documentation: dt: add the omap hwspinlock bindings document
    Date
    HwSpinlock IP is present only on OMAP4 and other newer SoCs,
    which are all device-tree boot only. This patch adds the
    DT bindings information for OMAP hwspinlock module.

    +OMAP4+ HwSpinlock Driver
    +========================
    +
    +Required properties:
    +- compatible: Should be "ti,omap4-hwspinlock" for
    + OMAP44xx, OMAP54xx, AM33xx, AM43xx, DRA7xx SoCs
    +- reg: Contains the hwspinlock module register address space
    + (base address and length)
    +- ti,hwmods: Name of the hwmod associated with the hwspinlock device
    +- #hwlock-cells: Should be 1. The OMAP hwspinlock users will use a
    + 0-indexed relative hwlock number as the argument
    + specifier value for requesting a specific hwspinlock
    + within a hwspinlock bank.
    +
    +
    +Example:
    +
    +/* OMAP4 */
    +hwspinlock: spinlock@4a0f6000 {
    + compatible = "ti,omap4-hwspinlock";
    + reg = <0x4a0f6000 0x1000>;
    + ti,hwmods = "spinlock";
    + #hwlock-cells = <1>;
    +};
