Commit Message

Dave Gerlach March 7, 2017, 10:22 a.m. UTC
Add a generic power domain implementation, TI SCI PM Domains, that
will hook into the genpd framework and allow the TI SCI protocol to
control device power states.

Also, provide macros representing each device index as understood
by TI SCI to be used in the device node power-domain references.
These are identifiers for the K2G devices managed by the PMMC.

The last sentence is mostly Linux implementation details. The binding is 
power domains. The Linux framework is PM domains. Let's keep those 
distinct and the latter doesn't belong in bindings.

Ok, I will send an update to just this patch and drop the last sentence above.

+Texas Instruments TI-SCI Generic Power Domain
+---------------------------------------------
+
+Some TI SoCs contain a system controller (like the PMMC, etc...) that is
+responsible for controlling 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.
+
+[1] Documentation/devicetree/bindings/arm/keystone/ti,sci.txt
+
+PM Domain Node
+==============
+The PM domain node represents the global PM domain managed by the PMMC, which
+in this case is the implementation as documented by the generic PM domain
+bindings in Documentation/devicetree/bindings/power/power_domain.txt.  Because
+this relies on the TI SCI protocol to communicate with the PMMC it must be a
+child of the pmmc node.
+
+Required Properties:
+--------------------
+- compatible: should be "ti,sci-pm-domain"
+- #power-domain-cells: Must be 1 so that an id can be provided in each
+		       device node.
+
+Example (K2G):
+-------------
+	pmmc: pmmc {
+		compatible = "ti,k2g-sci";
+		...
+
+		k2g_pds: power-controller {
+			compatible = "ti,sci-pm-domain";
+			#power-domain-cells = <1>;
+		};
+	};
+
+PM Domain Consumers
+===================
+Hardware blocks belonging to a PM domain should contain a "power-domains"
+property that is a phandle pointing to the corresponding PM domain node
+along with an index representing the device id to be passed to the PMMC
+for device control.
+
+Required Properties:
+--------------------
+- power-domains: phandle pointing to the corresponding PM domain node
+		 and an ID representing the device.
+
+See dt-bindings/genpd/k2g.h for the list of valid identifiers for k2g.
+
+Example (K2G):
+--------------------
+	uart0: serial@02530c00 {
+		compatible = "ns16550a";
+		...
+		power-domains = <&k2g_pds K2G_DEV_UART0>;
+	};
