+* Power Management Controller
+
+Properties:
+- compatible: "fsl,<chip>-pmc".
+
+ "fsl,mpc8349-pmc" should be listed for any chip whose PMC is
+ compatible. "fsl,mpc8313-pmc" should also be listed for any chip
+ whose PMC is compatible, and implies deep-sleep capability.
+
+ "fsl,mpc8548-pmc" should be listed for any chip whose PMC is
+ compatible. "fsl,mpc8536-pmc" should also be listed for any chip
+ whose PMC is compatible, and implies deep-sleep capability.
+
+ "fsl,mpc8641d-pmc" should be listed for any chip whose PMC is
+ compatible; all statements below that apply to "fsl,mpc8548-pmc" also
+ apply to "fsl,mpc8641d-pmc".
+
+ Compatibility does not include bit assignments in SCCR/PMCDR/DEVDISR; these
+ bit assignments are indicated via the sleep specifier in each device's
+ sleep property.
+
+- reg: For devices compatible with "fsl,mpc8349-pmc", the first resource
+ is the PMC block, and the second resource is the Clock Configuration
+ block.
+
+ For devices compatible with "fsl,mpc8548-pmc", the first resource
+ is a 32-byte block beginning with DEVDISR.
+
+- interrupts: For "fsl,mpc8349-pmc"-compatible devices, the first
+ resource is the PMC block interrupt.
+
+- fsl,mpc8313-wakeup-timer: For "fsl,mpc8313-pmc"-compatible devices,
+ this is a phandle to an "fsl,gtm" node on which timer 4 can be used as
+ a wakeup source from deep sleep.
+
+Sleep specifiers:
+
+ fsl,mpc8349-pmc: Sleep specifiers consist of one cell. For each bit
+ that is set in the cell, the corresponding bit in SCCR will be saved
+ and cleared on suspend, and restored on resume. This sleep controller
+ supports disabling and resuming devices at any time.
+
+ fsl,mpc8536-pmc: Sleep specifiers consist of three cells, the third of
+ which will be ORed into PMCDR upon suspend, and cleared from PMCDR
+ upon resume. The first two cells are as described for fsl,mpc8578-pmc.
+ This sleep controller only supports disabling devices during system
+ sleep, or permanently.
+
+ 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.
+
+Example:
+
+ power@b00 {
+ compatible = "fsl,mpc8313-pmc", "fsl,mpc8349-pmc";
+ reg = <0xb00 0x100 0xa00 0x100>;
+ interrupts = <80 8>;
+ };
