+ 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.
