>From dts-bindings/fsl/pmc.txt:
fsl,mpc8548-pmc: Sleep specifiers consist of one or two cells, the
first of which will be ORed into DEVDISR (and the second into
DEVDISR2, if present -- this cell should be zero or absent if the
hardware does not have DEVDISR2) upon a request for permanent device
disabling. This sleep controller does not support configuring devices
to disable during system sleep (unless supported by another compatible
match), or dynamically.
