3Properties:
4- compatible: "fsl,<chip>-pmc".
5
6  "fsl,mpc8349-pmc" should be listed for any chip whose PMC is
7  compatible.  "fsl,mpc8313-pmc" should also be listed for any chip
8  whose PMC is compatible, and implies deep-sleep capability.
9
10  "fsl,mpc8548-pmc" should be listed for any chip whose PMC is
11  compatible.  "fsl,mpc8536-pmc" should also be listed for any chip
12  whose PMC is compatible, and implies deep-sleep capability.
13
14  "fsl,mpc8641d-pmc" should be listed for any chip whose PMC is
15  compatible; all statements below that apply to "fsl,mpc8548-pmc" also
16  apply to "fsl,mpc8641d-pmc".
17
18  Compatibility does not include bit assignments in SCCR/PMCDR/DEVDISR; these
19  bit assignments are indicated via the sleep specifier in each device's
20  sleep property.
21
22- reg: For devices compatible with "fsl,mpc8349-pmc", the first resource
23  is the PMC block, and the second resource is the Clock Configuration
24  block.
25
26  For devices compatible with "fsl,mpc8548-pmc", the first resource
27  is a 32-byte block beginning with DEVDISR.
28
29- interrupts: For "fsl,mpc8349-pmc"-compatible devices, the first
30  resource is the PMC block interrupt.
31
32- fsl,mpc8313-wakeup-timer: For "fsl,mpc8313-pmc"-compatible devices,
33  this is a phandle to an "fsl,gtm" node on which timer 4 can be used as
34  a wakeup source from deep sleep.
35
36Sleep specifiers:
37
38  fsl,mpc8349-pmc: Sleep specifiers consist of one cell.  For each bit
39  that is set in the cell, the corresponding bit in SCCR will be saved
40  and cleared on suspend, and restored on resume.  This sleep controller
41  supports disabling and resuming devices at any time.
42
43  fsl,mpc8536-pmc: Sleep specifiers consist of three cells, the third of
44  which will be ORed into PMCDR upon suspend, and cleared from PMCDR
45  upon resume.  The first two cells are as described for fsl,mpc8578-pmc.
46  This sleep controller only supports disabling devices during system
47  sleep, or permanently.
48
49  fsl,mpc8548-pmc: Sleep specifiers consist of one or two cells, the
50  first of which will be ORed into DEVDISR (and the second into
51  DEVDISR2, if present -- this cell should be zero or absent if the
52  hardware does not have DEVDISR2) upon a request for permanent device
53  disabling.  This sleep controller does not support configuring devices
54  to disable during system sleep (unless supported by another compatible
55  match), or dynamically.
