-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>;
- #size-cells = <0>;
-
- port@0 {
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <0>;
-
- endpoint@0 {
- reg = <0>;
- ...
- };
- endpoint@1 {
- reg = <1>;
- ...
- };
- };
-
- port@1 {
- reg = <1>;
-
- endpoint { ... };
- };
-};
-
-All 'port' nodes can be grouped under an optional 'ports' node, which
-allows to specify #address-cells, #size-cells properties for the 'port'
-nodes independently from any other child device nodes a device might
-have.
-
-device {
- ...
- ports {
- #address-cells = <1>;
- #size-cells = <0>;
-
- port@0 {
- ...
- endpoint@0 { ... };
- endpoint@1 { ... };
- };
-
- port@1 { ... };
- };
-};
-
-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.

-* SPI NOR flash: ST M25Pxx (and similar) serial flash chips
-
-Required properties:
-- #address-cells, #size-cells : Must be present if the device has sub-nodes
- representing partitions.
-- compatible : May include a device-specific string consisting of the
- manufacturer and name of the chip. A list of supported chip
- names follows.
- Must also include "jedec,spi-nor" for any SPI NOR flash that can
- be identified by the JEDEC READ ID opcode (0x9F).
-
- Supported chip names:
- at25df321a

- 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;
- };
