Subject: [PATCH v4 1/1] dt-bindings: soc: fsl: Convert rcpm to yaml format
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@....com>
---
Change from v3 to v4
- Add missed fsl,ls1088a-rcpm, fsl,ls208xa-rcpm, fsl,lx2160a-rcpm
Chagne from v2 to v3
- fallback use const
- order as fallback compatible string
- remove minItems for compatible string
- Fix typo 1045a
Change from v1 to v2
- add missed compatible string
- Remove compatible string map table
- use oneof Item to align compatible string map table

-* 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@...00 {
- compatible = "fsl,t4240-rcpm", "fsl,qoriq-rcpm-2.0";
- reg = <0xe2000 0x1000>;
- #fsl,rcpm-wakeup-cells = <2>;
- };
-

-can be used as a wakeup source.

- clocks = <&sysclk>;
- clock-names = "ipg";
