Hi, I am working on adding adv7280-m support on an imx6q based board and I am facing two issues that prevent the adv7180 driver to be successfully probed: 1. The write to the ADV7182_REG_INPUT_VIDSEL register inside adv7182_set_std() fails. 2. The write to the ADV7180_REG_ICONF1 register (interrupt page address space) inside init_device() fails. If I force a hack by ignoring the adv7182_set_std() failure and remove the interrupt description in the device tree then the probe succeeds. A different board based on imx6dl with an adv7280 connected to the parallel CSI works fine running the same 5.4 kernel. I could not locate any in-tree user of the "adv7280-m" compatible and I am trying to properly fix the probe issues. Does anyone have any suggestions as to why these registers writes fail only on the ADV7280-M connected to the MIPI CSI2 port case? Thanks, Fabio Estevam
