The dt binding describes only the isl79987 chip, which supports MIPI CSI-2. The driver could be extended to handle isl79988 (for BT.656), too, but this isn't implemented. In v4, I added a patch for the imx6-mipi-csi2 to use the pre_streamon/post_streamoff call to set the MIPI CSI-2 transmitter into LP11 mode, which is required by its startup sequence. The isl7998x implements the callbacks to power up the decoder. Furthermore, I updated the driver following the review feedback of v3, rebased the series on media/master based on 5.15-rc2, and cleaned up the logging. I tried to fix lines with a length of over 80 characters, but I had to skip a few locations, where it made things worse. The full changelog is in the respective patches.
