From: Dave Gerlach <redacted>

Add a generic power domain implementation, TI SCI PM Domains, that
will hook into the genpd framework and allow each PD, which will be
created one per device, to be managed over the TI-SCI protocol.

+Texas Instruments TI-SCI Generic Power Domain
+---------------------------------------------
+
+Some TI SoCs contain a system controller (like the PMMC, etc...) that are
+responsible for control the state of the IPs that are present. Communication
+between the host processor running an OS and the system controller happens
+through a protocol known as TI-SCI[1]. This pm domain implementation plugs into
+the generic pm domain framework and makes use of the TI SCI protocol power on
+and off each device when needed.

+PM Domains Nodes
+================
+The PM domains node represents the global PM domain managed by the PMMC,
+which in this case is one cell implementation as documented by the generic
+PM domain bindings in
+Documentation/devicetree/bindings/power/power_domain.txt.
+
+Required Properties:
+--------------------
+- compatible: should be "ti,sci-pm-domains"
+- #power-domain-cells: Must be 1 so that an offset can be provided in each
+		       device node.
+- ti,sci: Phandle to the TI SCI device to use for managing the devices
