+   To associate a device with the corresponding bits in a power or
+   clock disable register, a device can contain a "sleep" property.
+
+   The first cell of a sleep node is a phandle to the sleep controller.
+   The remaining cells are interpreted by said controller.  In the case
+   of an fsl,mpc83xx-pmc sleep controller, the second cell represents the
+   bits to clear in SCCR to stop the device's clock.
+
    More devices will be defined as this spec matures.
