OMAP Counter-32K bindings
Required properties:
- compatible: Must be "ti,omap-counter32k" for OMAP controllers
- reg: Contains timer register address range (base address and length)
- ti,hwmods: Name of the hwmod associated to the counter, which is typically
"counter_32k"
Example:
counter32k: counter@4a304000 {
compatible = "ti,omap-counter32k";
reg = <0x4a304000 0x20>;
ti,hwmods = "counter_32k";
};
