Just, also sent an e-mail in response to Otavio on this.
Thanks for quick responses!!!


Using imx7d:

I noticed (as I am attempting to apply patches we use), that /arch/arm/mach-imx/cpuidle-imx7d.c exists in the 5.4.X.imx version we are currently using, but is not present in 5.12.  But mach-imx7d.c is.
 Will I have to add files (via patches) to fully support imx7d vs. what we had in the freescale 5.4.X.imx release?

Thanks a ton,
  Val

Yes, it is a good approach to move to a mainline kernel.

One important aspect to consider is what is the i.MX SoC that you are using.

imx28/imx5/imx6/imx7 have decent support in the upstream kernel.
imx8m/imx8mm are getting better.

imx8qxp has a minimum support upstream in 5.12.
