These bindings allow to describe most known standard USB connectors and it should be possible to extend it if necessary. USB connectors, beside USB can be used to route other protocols, for example UART, Audio, MHL. In such case every device passing data through the connector should have appropriate graph bindings.
Signed-off-by: Andrzej Hajda a.hajda@samsung.com
v4:
- improved 'type' description (Rob),
- improved description of 2nd example (Rob).
v3:
- removed MHL port (samsung connector will have separate bindings),
- added 2nd example for USB-C,
- improved formatting.
v2:
- moved connector type(A,B,C) to compatible string (Rob),
- renamed size property to type (Rob),
- changed type description to be less confusing (Laurent),
- removed vendor specific compatibles (implied by graph port number),
- added requirement of connector being a child of IC (Rob),
- removed max-mode (subtly suggested by Rob, it should be detected anyway by USB Controller in runtime, downside is that device is not able to report its real capabilities, maybe better would be to make it optional(?)),
- assigned port numbers to data buses (Rob).
Regards Andrzej
