Convert dt-binding rcpm from txt to yaml format.
Add fsl,ls1028a-rcpm compatible string.
Additional changes:
- Add missed compatible string fsl,<chip>-rcpm.
- Remove map fsl,<chip>-rcpm to fsl,qoriq-rcpm-<version>.
Signed-off-by: Frank Li <Frank.Li@xxxxxxx>
---
Change from v1 to v2
- add missed compatible string
- Remove compatible string map table
- use oneof Item to align compatible string map table
- Fix typo 1045a

-* Run Control and Power Management
--------------------------------------------
-The RCPM performs all device-level tasks associated with device run control
-and power management.
-
-Required properites:
- - reg : Offset and length of the register set of the RCPM block.
- - #fsl,rcpm-wakeup-cells : The number of IPPDEXPCR register cells in the
- fsl,rcpm-wakeup property.
- - compatible : Must contain a chip-specific RCPM block compatible string
- and (if applicable) may contain a chassis-version RCPM compatible
- string. Chip-specific strings are of the form "fsl,<chip>-rcpm",
- such as:
- * "fsl,p2041-rcpm"
- * "fsl,p5020-rcpm"
- * "fsl,t4240-rcpm"
-
- Chassis-version strings are of the form "fsl,qoriq-rcpm-<version>",
- such as:
- * "fsl,qoriq-rcpm-1.0": for chassis 1.0 rcpm
- * "fsl,qoriq-rcpm-2.0": for chassis 2.0 rcpm
- * "fsl,qoriq-rcpm-2.1": for chassis 2.1 rcpm
- * "fsl,qoriq-rcpm-2.1+": for chassis 2.1+ rcpm
-
-All references to "1.0" and "2.0" refer to the QorIQ chassis version to
-which the chip complies.
-Chassis Version Example Chips
---------------- -------------------------------
-1.0 p4080, p5020, p5040, p2041, p3041
-2.0 t4240, b4860, b4420
-2.1 t1040,
-2.1+ ls1021a, ls1012a, ls1043a, ls1046a
-
-Optional properties:
- - little-endian : RCPM register block is Little Endian. Without it RCPM
- will be Big Endian (default case).
-
-Example:
-The RCPM node for T4240:
- rcpm: global-utilities@e2000 {
- compatible = "fsl,t4240-rcpm", "fsl,qoriq-rcpm-2.0";
- reg = <0xe2000 0x1000>;
- #fsl,rcpm-wakeup-cells = <2>;
- };
-
-* Freescale RCPM Wakeup Source Device Tree Bindings
--------------------------------------------
-Required fsl,rcpm-wakeup property should be added to a device node if the device
-can be used as a wakeup source.
-
- - fsl,rcpm-wakeup: Consists of a phandle to the rcpm node and the IPPDEXPCR
- register cells. The number of IPPDEXPCR register cells is defined in
- "#fsl,rcpm-wakeup-cells" in the rcpm node. The first register cell is

- cell is for IPPDEXPCR1, and so on.
-

- reg = <0x0 0x2950000 0x0 0x1000>;

- clocks = <&sysclk>;
- clock-names = "ipg";
- fsl,rcpm-wakeup = <&rcpm 0x0 0x40000000>;
