-Device Tree Bindings for the Xilinx Zynq MPSoC Power Management
---------------------------------------------------------------------
-The zynqmp-power node describes the power management configurations.
-It will control remote suspend/shutdown interfaces.
-
-Required properties:
- - compatible: Must contain: "xlnx,zynqmp-power"
- - interrupts: Interrupt specifier
-
-Optional properties:
- - mbox-names : Name given to channels seen in the 'mboxes' property.
- "tx" - Mailbox corresponding to transmit path
- "rx" - Mailbox corresponding to receive path
- - mboxes : Standard property to specify a Mailbox. Each value of
- the mboxes property should contain a phandle to the
- mailbox controller device node and an args specifier
- that will be the phandle to the intended sub-mailbox
- child node to be used for communication. See
- Documentation/devicetree/bindings/mailbox/mailbox.txt
- for more details about the generic mailbox controller
- and client driver bindings. Also see
- Documentation/devicetree/bindings/mailbox/ \
- xlnx,zynqmp-ipi-mailbox.txt for typical controller that
- is used to communicate with this System controllers.

-Examples

-
-Example with interrupt method:
-
-firmware {
- zynqmp_firmware: zynqmp-firmware {
- compatible = "xlnx,zynqmp-firmware";
- method = "smc";
-
- zynqmp_power: zynqmp-power {
- compatible = "xlnx,zynqmp-power";
- interrupts = <0 35 4>;
- };
- };
-};
-
-Example with IPI mailbox method:
-
-firmware {
- zynqmp_firmware: zynqmp-firmware {
- compatible = "xlnx,zynqmp-firmware";
- method = "smc";
-
- zynqmp_power: zynqmp-power {
- compatible = "xlnx,zynqmp-power";
- interrupt-parent = <&gic>;
- interrupts = <0 35 4>;
- mboxes = <&ipi_mailbox_pmu0 0>,
- <&ipi_mailbox_pmu0 1>;
- mbox-names = "tx", "rx";
- };
- };
-};
