Subject: [PATCH 1/1] dt-bindings: rtc: Convert rtc-fsl-ftm-alarm.txt to yaml format
Convert dt-binding doc "rtc-fsl-ftm-alarm.txt" to yaml format.
Change example's reg to 32bit address and length.
Remove unrelated rcpm@...4040 in example.

-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@...4040 {
- compatible = "fsl,ls1088a-rcpm", "fsl,qoriq-rcpm-2.1+";
- reg = <0x0 0x1e34040 0x0 0x18>;
- #fsl,rcpm-wakeup-cells = <6>;
-};

-ftm_alarm0: timer@...0000 {
- compatible = "fsl,ls1088a-ftm-alarm";
- reg = <0x0 0x2800000 0x0 0x10000>;
- fsl,rcpm-wakeup = <&rcpm 0x0 0x0 0x0 0x0 0x4000 0x0>;
- interrupts = <0 44 4>;
