TI HwSpinlock for OMAP and K3 based SoCs
=========================================
Required properties:
- compatible: Should be one of the following,
"ti,omap4-hwspinlock" for
OMAP44xx, OMAP54xx, AM33xx, AM43xx, DRA7xx SoCs
"ti,am654-hwspinlock" for
K3 AM65x and J721E SoCs
- reg: Contains the hwspinlock module register address space
(base address and length)
- ti,hwmods: Name of the hwmod associated with the hwspinlock device
(for OMAP architecture based SoCs only)
- #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.
Please look at the generic hwlock binding for usage information for consumers,
"Documentation/devicetree/bindings/hwlock/hwlock.txt"
Example:
1. OMAP4 SoCs
hwspinlock: spinlock@4a0f6000 {
compatible = "ti,omap4-hwspinlock";
reg = <0x4a0f6000 0x1000>;
ti,hwmods = "spinlock";
#hwlock-cells = <1>;
};
2. AM65x SoCs and J721E SoCs
&cbass_main {
cbass_main_navss: interconnect0 {
hwspinlock: spinlock@30e00000 {
compatible = "ti,am654-hwspinlock";
reg = <0x00 0x30e00000 0x00 0x1000>;
#hwlock-cells = <1>;
};
};
};
