 Required properites:

-  - fsl,#rcpm-wakeup-cells : The number of IPPDEXPCR register cells in the
-	fsl,rcpm-wakeup property.

 	string. Chip-specific strings are of the form "fsl,<chip>-rcpm",

+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>;

--------------------------------------------
-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>;
