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