Hi Krzysztof,

Did you finish this patchset for applying git repository?
I can't find this patchset on mainline kernel.

If this patchset isn't applied on mainline, I'd like you to finish this patch
because I want to maintain up to date patch for max77836/max14577 on mainline.

Thanks,
Chanwoo Choi
