That would have been useful information in the commit message.

I think you should first fix the i.MX95 problem, and add i.MX952 support
on top.

If the pixel link always aligns data to the MSB, as you stated, does it
mean that not setting CHNL_CTRL_RAW_IN_MSB_ALIGN would always result in
dropping the MSBs of each pixel, essentially breaking ISI operation ?
What is the use case for making the CHNL_CTRL_RAW_IN_MSB_ALIGN bit
configurable if it must always be set for proper operation ?

If i.MX95 can't produce the V4L2 RAW1[024] formats at all, then they
should be filtered out, yes.
