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>;
|
|
};
|
|
};
|
|
};
