     * 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>;
            };
