Hello, this series is a followup to the other series [1] started by Niklas Söderlund where only the first patch has been merged. The overall idea is to be more compliant with the Renesas hardware manual which requires a reset or stop of capture in the VIN module before reset of CSI2. Another goal (achieved by the patch 3/3) is to be more resilient with respect to non-critical CSI2 errors so the driver does not end in an endless restart loop. Patch 1/3 has been taken from [1] with some additional documentation changes. Patch 2/3 is included without any changes. Patch 3/3 is based on discussions in [2], where I also found one method to trigger CSI2 errors in the video pipeline on a Salvator board for testing by manipulating CSI2-related registers in the adv7482: $ i2cset -f -y 4 0x64 0x00 0x04 $ i2cset -f -y 4 0x64 0x00 0x24 [1] https://lore.kernel.org/linux-renesas-soc/20211108160220.767586-1-niklas.soderlund+renesas@xxxxxxxxxxxx/ [2] https://lore.kernel.org/linux-renesas-soc/20220309192707.GA62903@xxxxxxxxxxxxxxxxxxxxxx/
