* of: Explicitly include linux/types.h in of_graph.hMark Brown2015-03-261-0/+2
| | | | | | | | | | | | | | | In current -next of_graph.h fails to build due to it relying on linux/types.h without explicitly including it: ../include/linux/of_graph.h:43:71: error: unknown type name 'u32' caused by bfe446e37c4e (of: Add of_graph_get_port_by_id function). Add an explicit inclusion to fix this.

* of: Add of_graph_get_port_by_id functionPhilipp Zabel2015-02-231-0/+7
| | | | | | | | This patch adds a function to get a port device tree node by port id, or reg property value. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
* of: Add for_each_endpoint_of_node helper macroPhilipp Zabel2015-02-231-0/+11
| | | | | | | | | Note that while of_graph_get_next_endpoint decrements the reference count of the child node passed to it, of_node_put(child) still has to be called manually when breaking out of the loop.

* [media] of: move common endpoint parsing to drivers/ofPhilipp Zabel2014-03-061-0/+20
| | | | | | | | | | | | | | 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/ofPhilipp Zabel2014-03-061-0/+46
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.
