[media] of: move common endpoint parsing to drivers/of

2014-03-06T16:41:48Z

This patch adds a new struct of_endpoint which is then embedded in struct v4l2_of_endpoint and contains the endpoint properties that are not V4L2 (or even media) specific: the port number, endpoint id, local device tree node and remote endpoint phandle. of_graph_parse_endpoint parses those properties and is used by v4l2_of_parse_endpoint, which just adds the V4L2 MBUS information to the containing v4l2_of_endpoint structure.

[media] of: move graph helpers from drivers/media/v4l2-core to drivers/of

2014-03-06T16:41:22Z

This patch moves the parsing helpers used to parse connected graphs in the device tree, like the video interface bindings documented in Documentation/devicetree/bindings/media/video-interfaces.txt, from drivers/media/v4l2-core/v4l2-of.c into drivers/of/base.c. This allows to reuse the same parser code from outside the V4L2 framework, most importantly from display drivers. The functions v4l2_of_get_next_endpoint, v4l2_of_get_remote_port, and v4l2_of_get_remote_port_parent are moved. They are renamed to of_graph_get_next_endpoint, of_graph_get_remote_port, and of_graph_get_remote_port_parent, respectively. Since there are not that many current users yet, switch all of them to the new functions right away.
