-Common bindings for device graphs
-
-General concept
----------------
-
-The hierarchical organisation of the device tree is well suited to describe
-control flow to devices, but there can be more complex connections between
-devices that work together to form a logical compound device, following an
-arbitrarily complex graph.
-There already is a simple directed graph between devices tree nodes using
-phandle properties pointing to other nodes to describe connections that
-can not be inferred from device tree parent-child relationships. The device
-tree graph bindings described herein abstract more complex devices that can
-have multiple specifiable ports, each of which can be linked to one or more
-ports of other devices.
-
-These common bindings do not contain any information about the direction or
-type of the connections, they just map their existence. Specific properties
-may be described by specialized bindings depending on the type of connection.
-
-To see how this binding applies to video pipelines, for example, see
-Documentation/devicetree/bindings/media/video-interfaces.txt.
-Here the ports describe data interfaces, and the links between them are
-the connecting data buses. A single port with multiple connections can
-correspond to multiple devices being connected to the same physical bus.
-
-Organisation of ports and endpoints
------------------------------------
-
-Ports are described by child 'port' nodes contained in the device node.
-Each port node contains an 'endpoint' subnode for each remote device port
-connected to this port. If a single port is connected to more than one
-remote device, an 'endpoint' child node must be provided for each link.
-If more than one port is present in a device node or there is more than one
-endpoint at a port, or a port node needs to be associated with a selected
-hardware interface, a common scheme using '#address-cells', '#size-cells'
-and 'reg' properties is used to number the nodes.
-
-device {
-        ...
-        #address-cells = <1>;

-All 'port' nodes can be grouped under an optional 'ports' node, which

-
-Links between endpoints
------------------------
-
-Each endpoint should contain a 'remote-endpoint' phandle property that points
-to the corresponding endpoint in the port of the remote device. In turn, the
-remote endpoint should contain a 'remote-endpoint' property. If it has one, it
-must not point to anything other than the local endpoint. Two endpoints with
-their 'remote-endpoint' phandles pointing at each other form a link between the
-containing ports.
-
-device-1 {
-        port {
-                device_1_output: endpoint {
-                        remote-endpoint = <&device_2_input>;
-                };
-        };
-};
-
-device-2 {
-        port {
-                device_2_input: endpoint {
-                        remote-endpoint = <&device_1_output>;
-                };
-        };
-};
-
-Required properties
--------------------
-
-If there is more than one 'port' or more than one 'endpoint' node or 'reg'
-property present in the port and/or endpoint nodes then the following
-properties are required in a relevant parent node:
-
- - #address-cells : number of cells required to define port/endpoint
-                    identifier, should be 1.
- - #size-cells    : should be zero.
-
-Optional endpoint properties
-----------------------------
-
-- remote-endpoint: phandle to an 'endpoint' subnode of a remote device node.

-               The following chip names have been used historically to
-               designate quirky versions of flash chips that do not support the
-               JEDEC READ ID opcode (0x9F):
-                 m25p05-nonjedec
-                 m25p10-nonjedec
-                 m25p20-nonjedec
-                 m25p40-nonjedec
-                 m25p80-nonjedec
-                 m25p16-nonjedec
-                 m25p32-nonjedec
-                 m25p64-nonjedec
-                 m25p128-nonjedec
-
-- reg : Chip-Select number
-- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at
-
-Optional properties:
-- m25p,fast-read : Use the "fast read" opcode to read data from the chip instead
-                   of the usual "read" opcode. This opcode is not supported by
-                   all chips and support for it can not be detected at runtime.
-                   Refer to your chips' datasheet to check if this is supported
-                   by your chip.
-- broken-flash-reset : Some flash devices utilize stateful addressing modes
-		   (e.g., for 32-bit addressing) which need to be managed
-		   carefully by a system. Because these sorts of flash don't
-		   have a standardized software reset command, and because some
-		   systems don't toggle the flash RESET# pin upon system reset
-		   (if the pin even exists at all), there are systems which
-		   cannot reboot properly if the flash is left in the "wrong"
-		   state. This boolean flag can be used on such systems, to
-		   denote the absence of a reliable reset mechanism.
-
-Example:
-
-	flash: m25p80@0 {
-		#address-cells = <1>;
-		#size-cells = <1>;
-		compatible = "spansion,m25p80", "jedec,spi-nor";
-		reg = <0>;
-		spi-max-frequency = <40000000>;
-		m25p,fast-read;
-	};
