4 - compatible: "fsl,<chip>-pmc".
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.
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.
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".
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
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
26 For devices compatible with "fsl,mpc8548-pmc", the first resource
27 is a 32-byte block beginning with DEVDISR.
29 - interrupts: For "fsl,mpc8349-pmc"-compatible devices, the first
30 resource is the PMC block interrupt.
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.
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.
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.
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.
