Hi, This series extend the VIN interrupt handling to be able to generate FRAME_SYNC events. Having these events in user-space is a great help to know when a sensor starts to expose a new frame. Patch 1/3 and 2/3 prepays the existing interrupt infrastructure to support more then "frame captured" interrupts. While patch 3/3 enables and checks for VSYNC detection and generates the new event. The feature is tested on Gen2, Gen3 and Gen4 and all devices correctly generate FRAME_SYNC events.
