Hi Stanislav!

There is patch #1 that did my friend, Alexander A. Mityaev.
Patch cover to things:
1. enable support of RT5350
2. enable FDT configuration for RTxxxx family

First thing may help you to bring if_rt up. Second one may help to work
in right direction, because FDT makes adding new SoC support to looks
like writing config (except some new devices, which will require new
driver for it).

I'm glad to help, but currently limited in time I can spend.
Anyway, I will try to answer your questions ASAP.

Thank you!
