No.

If you want to set time scales, please put up money to find the work to
come up with those proposals.

Virtually no one here is a charity; the charity days of open source are
long gone.  Everyone needs money to put food in their mouths, and the
way this works is that those who pay the most get the time.  That's the
nature of a open and free market.

What's more is that you have been given some good proposals already:
converting the fex description to DT for the kernel.  Wow, that means you
can use the work which has already been done in the mainline kernel for
free!  How cool is that!
