2021-01-26media: software_node: Add support for fwnode_graph*() family of functionsHeikki Krogerus1-1/+114
This implements the remaining .graph_*() callbacks in the fwnode operations structure for the software nodes. That makes the fwnode_graph_*() functions available in the drivers also when software nodes are used. The implementation tries to mimic the "OF graph" as much as possible, but there is no support for the "reg" device property. The ports will need to have the index in their name which starts with "port@" (for example "port@0", "port@1", ...) and endpoints will use the index of the software node that is given to them during creation. The port nodes can also be grouped under a specially named "ports" subnode, just like in DT, if necessary. The remote-endpoints are reference properties under the endpoint nodes that are named "remote-endpoint".

2021-01-26media: software_node: Enforce parent before child ordering of nodes arraysDaniel Scally1-12/+30
Registering software_nodes with the .parent member set to point to a currently unregistered software_node has the potential for problems, so enforce parent -> child ordering in arrays passed in to software_node_register_nodes(). Software nodes that are children of another software node should be unregistered before their parent. To allow easy unregistering of an array of software_nodes ordered parent to child, reverse the order in which software_node_unregister_nodes() unregisters software_nodes.

On i.MX6UL/i.MX6ULL there is no CSI mux at all, so do not return an error when the entity is not a video mux and assign the IMX_MEDIA_GRP_ID_CSI_MUX group id only when appropriate.

GCC with W=2 level of kernel compiler warnings warns about the use of uninitialised variables in a few locations. While these uninitialised variables were not used in reality, this still produced compiler warnings. Address this by assigning the variables to NULL and checking for NULL in places it is not expected, returning -EIO in that case. This provides at least some sanity checking at runtime as the compiler appears unable to do that at compile time.
