![]() This migrates rk_vop (the shared functions used by multiple VOP mini-drivers) to be compatible with a live tree. Unfortunately, there's (i) a lot of tree traversal needed for a VOP (as each active VOP vnode references back to the endpoints in the encoders and vice versa) to configure the connection between VOPs and encoders; (ii) the DTS binding is not too sane and one needs to walk a node's parents (the original code just assumed that the device would live 3 levels above the property linked through a phandle) until a UCLASS_DISPLAY device can be found. As part of the migration, the code for finding the enclosing display device has been changed to not assume a specific depth of nesting (i.e. we walk until we reach the root or find a matching device) and to use the newly introduced (in the same series) ofnode_get_parent() function.
