+Optional properties:
+ - big-endian : Indicate RCPM registers is big-endian. A RCPM node
+ that doesn't have this property will be regarded as little-endian.
+ - <property 'compatible' string of consumer device> : This string
+ is referred by RCPM driver to judge if the consumer (such as flex timer)
+ is able to be regards as wakeup source or not, such as 'fsl,ls1012a-ftm'.
+ Further, this property will carry the bit mask info to control
+ coresponding wake up source.
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
- cell is for IPPDEXPCR1, and so on.
-
- Note: IPPDEXPCR(IP Powerdown Exception Control Register) provides a
- mechanism for keeping certain blocks awake during STANDBY and MEM, in
- order to use them as wake-up sources.
-
-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>;

+ fsl,ls1012a-ftm = <0x20000>;
