Hello all This series adds a driver for the Input Video Control Block in the RZ/V2H SoC. The IVC block transmits input image data from memory to the ISP core (on this SoC, a Mali-C55 ISP). The driver registers an output video device for userspace to queue image buffers to. One noteworthy feature is that - because it is not a part of the main ISP drive - the IVC driver also registers a subdevice, which connects to the media device created by the ISP driver through the usual v4l2 async framework. This requires delaying the registration of the video device until the .registered() callback of the subdevice, so that the struct v4l2_dev pointer the subdevice connected to can be set to the video device. This version of the driver drops the reliance on the new media framework that was posted recently [1], so can be merged without it and updated later. The series is also based on top of the latest version of the Mali-C55 driver [2].

--- Changes in v4: - Dropped the mc / V4L2 helper patches - they're in the C55 series instead, the aim being to avoid creating a circular dependency between the two sets - Link to v3: https://lore.kernel.org/r/20250704-ivc-v3-0-5c45d936ef2e@xxxxxxxxxxxxxxxx Changes in v3: - Added two new patches that create helpers in V4L2 and mc core that the driver then consumes. - Link to v2: https://lore.kernel.org/r/20250624-ivc-v2-0-e4ecdddb0a96@xxxxxxxxxxxxxxxx The rest of this message is the v4l2-compliance report for the video device and subdevice: v4l2-compliance 1.31.0-5380, 64
