#1417978 — [PATCH 0/2] Add pl031 RTC support for Hi6220/HiKey

This patchset enables the pl031 RTC on the Hi6220 SoC.

I wanted to submit it out for review and consideration to be merged.

Please let me know how best these two patches should go upstream
(independently via separate maintainers trees, or acked and through
one?).

thanks
