| * 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>; |
