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>.

* 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
|

the bit mask that should be set in IPPDEXPCR0, and the second register

Note: IPPDEXPCR(IP Powerdown Exception Control Register) provides a
|
||||

|

|

Example:
|

lpuart0: serial@2950000 {
|
||||
compatible = "fsl,ls1021a-lpuart";
|

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

interrupts = <GIC_SPI 80 IRQ_TYPE_LEVEL_HIGH>;

clocks = <&sysclk>;
|

clock-names = "ipg";
|

fsl,rcpm-wakeup = <&rcpm 0x0 0x40000000>;
