From: Sakari Ailus <[email protected]> Pixelrate is an essential part of the image data parameters. Add this. Together, the current parameters also define the frame rate.
Sensors do not have a concept of frame rate; pixelrate is much more meaningful in this context. Also, it is best to combine the pixelrate with the other format parameters since there are dependencies between them.
