Hi Gregory
Thanks for these RFC patches. I can confirm they work on my Openblocks
device with an A0 stepping SoC. I can now access the RTC.
You missed adding the new DTS file to the Makefile. Depending on how
the discussion goes about auto detecting stepping or not, i would of
used different filenames, probably:
armada-xp-openblocks-ax3-4.dts
armada-xp-openblocks-ax3-4-a0.dts
armada-xp-openblocks-ax3-4-common.dts
Keeps all the files together when listed alphabetically
Thanks
Andrew
