  Hi!

This series adds a new control for the vertical total time.
As camera sensors usually have registers regarding the total time and
not the blanking time, this would simplify driver implementations and
could therefore be seen as a replacement or upgrade for V4L2_CID_VBLANK.
Additionally, its value is independent from format changes and therefore
simplifies calculations in user space.

2/2 implements it for the imx290, basically extending the current
V4L2_CID_VBLANK implementation.
