Thanks - good to know someone is interested in this!

Is there someone we can cc with commit access that can review and
merge these? It looks to me like your patches can just go right on top
of mine. I'm unclear as to how much testing/feedback is needed before
we can switch the kernel from 5.15 to 6.1. I've tested it on an imx6
board, and you've tested it on an imx7 board so perhaps that is
enough.

Can you explain how do you go about coming up with your config-default
changes? I'm not a big fan of the config-default files over each
subtarget simply having its own defconfig but perhaps it's because I'm
unclear how to create and update the config-default.

Best Regards,

Tim
