Laurent Pinchart fc845e520b [media] v4l: vsp1: Support runtime modification of controls ... Controls are applied to the hardware in the configure operation of the VSP entities, which is only called when starting the video stream. To enable runtime modification of controls we need to call the configure operations for every frame. Doing so is currently not safe, as most parameters shouldn't be modified during streaming. Furthermore the configure operation can sleep, preventing it from being called from the frame completion interrupt handler for the next frame. Fix this by adding an argument to the configure operation to tell entities whether to perform a full configuration (as done now) or a partial runtime configuration. In the latter case the operation will only configure the subset of parameters related to runtime-configurable controls, and won't be allowed to sleep when doing so. Because partial reconfiguration can depend on parameters computed when performing a full configuration, the core guarantees that the configure operation will always be called with full and partial modes in that order at stream start. Entities thus don't have to duplicate configuration steps in the full and partial code paths. This change affects the VSP driver core only, all entities return immediately from the configure operation when called for a partial runtime configuration. Entities will be modified one by one in further commits.
