   1 TI HwSpinlock for OMAP and K3 based SoCs
   2 =========================================
   3
   4 Required properties:
   5 - compatible:           Should be one of the following,
   6                           "ti,omap4-hwspinlock" for
   7                                 OMAP44xx, OMAP54xx, AM33xx, AM43xx, DRA7xx SoCs
   8                           "ti,am654-hwspinlock" for
   9                                 K3 AM65x and J721E SoCs
  10 - reg:                  Contains the hwspinlock module register address space
  11                         (base address and length)
  12 - ti,hwmods:            Name of the hwmod associated with the hwspinlock device
  13                         (for OMAP architecture based SoCs only)
  14 - #hwlock-cells:        Should be 1. The OMAP hwspinlock users will use a
  15                         0-indexed relative hwlock number as the argument
  16                         specifier value for requesting a specific hwspinlock
  17                         within a hwspinlock bank.

  19 Please look at the generic hwlock binding for usage information for consumers,

  22 Example:
  23
  24 1. OMAP4 SoCs
  25 hwspinlock: spinlock@4a0f6000 {
  26         compatible = "ti,omap4-hwspinlock";
  27         reg = <0x4a0f6000 0x1000>;
  28         ti,hwmods = "spinlock";
  29         #hwlock-cells = <1>;
  30 };
  31
  32 2. AM65x SoCs and J721E SoCs
  33 &cbass_main {
  34         cbass_main_navss: interconnect0 {
  35                 hwspinlock: spinlock@30e00000 {
  36                         compatible = "ti,am654-hwspinlock";
  37                         reg = <0x00 0x30e00000 0x00 0x1000>;
  38                         #hwlock-cells = <1>;
  39                 };
  40         };
  41 };
