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.
|
|
|
|
Please look at the generic hwlock binding for usage information for consumers,
|
|
"Documentation/devicetree/bindings/hwlock/hwlock.txt"
|
|
|
|
Example:
|
|
|
|
/* OMAP4 */
|
|
hwspinlock: spinlock@4a0f6000 {
|
|
compatible = "ti,omap4-hwspinlock";
|
|
reg = <0x4a0f6000 0x1000>;
|
|
ti,hwmods = "spinlock";
|
|
#hwlock-cells = <1>;
|
|
};
