Without Steve's patch, I see the captured image slowly scrolling vertically, like an old tube TV. Once I apply it, the image becomes stable. The board I am currently using is based on an imx6dl and the ADV7180 is connected to the parallel CSI bus. > I'm asking because with my setup with the imx7 CSI driver I'm getting a > stable image, but it has a vertical and horizontal offset that seems to > vary each time I enable the camera.

Yes, maybe the imx7 CSI driver needs this initial frame skipping mechanism too. > But still I'm not really sure if we can compare this as I needed another > patch for the adv7180 driver to get it working with the i.MX8MM in the > first place: > https://git.kontron-electronics.de/linux/linux/-/commit/0d90331a44d0f718b7327a94fc72612ddcb4ac0f. Thanks for sharing your git tree. In the next days, I will work on a different imx6dl board, with the adv7180 connected to the MIPI CSI2. I see your tree contains some adv7180-m related patches. I will give it a try and report. Thanks, Fabio Estevam
