Freescale FlexTimer Module (FTM) Alarm
Required properties:
- compatible : Should be "fsl,<chip>-ftm-alarm", the
supported chips include
"fsl,ls1012a-ftm-alarm"
"fsl,ls1021a-ftm-alarm"
"fsl,ls1028a-ftm-alarm"
"fsl,ls1043a-ftm-alarm"
"fsl,ls1046a-ftm-alarm"
"fsl,ls1088a-ftm-alarm"
"fsl,ls208xa-ftm-alarm"
"fsl,lx2160a-ftm-alarm"
- reg : Specifies base physical address and size of the register sets for the
FlexTimer Module.
- interrupts : Should be the FlexTimer Module interrupt.
- fsl,rcpm-wakeup property and rcpm node : Please refer
Documentation/devicetree/bindings/soc/fsl/rcpm.txt
Optional properties:
- big-endian: If the host controller is big-endian mode, specify this property.
The default endian mode is little-endian.
Example:
rcpm: rcpm@1e34040 {
compatible = "fsl,ls1088a-rcpm", "fsl,qoriq-rcpm-2.1+";
reg = <0x0 0x1e34040 0x0 0x18>;
#fsl,rcpm-wakeup-cells = <6>;
};
ftm_alarm0: timer@2800000 {
compatible = "fsl,ls1088a-ftm-alarm";
reg = <0x0 0x2800000 0x0 0x10000>;
fsl,rcpm-wakeup = <&rcpm 0x0 0x0 0x0 0x0 0x4000 0x0>;
interrupts = <0 44 4>;
};
