Sure, sounds good. Great to head the 64-bit parts actually work. It would be great to have a Kconfig.platforms entry for it and maybe one .dts file either for a reference machine, or one of the products you work with. > I'm of course not in the position to submit patches you found in their > github account, but maybe there is another solution. Why not? As long as the code looks reasonable and has a GPLv2 compatible license, you should be able to take any small or large subset of their work and send it our way.
