Hi,

This series is an RFC to fix the i2c bus hang on A0 version of the
Armada XP SoCs. It occured on the the eraly release of the OpenBlocks
AX3-4 bords. Indeed the first variants of Armada XP SoCs (A0 stepping)
have issues related to the i2c controller which prevent to use the
offload mechanism and lead to a kernel hang during boot.

The best solution will be to detect the SoCs version at runtime and
use it in the driver, but I chosed to submit this version in case CPU
version detection feature takes more time than expected (and we
already reached the rc6 kernel).

Thanks,

Gregory

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:

Thanks for your feedback. In case there will be a second version I will
take them into account. However I hope we won't need it as I sent a
new series to fix this bug by dynamically getting the SoC revision.

armada-xp-openblocks-ax3-4.dts
armada-xp-openblocks-ax3-4-a0.dts
armada-xp-openblocks-ax3-4-common.dts

you probably meant armada-xp-openblocks-ax3-4-common.dtsi, but I got the
point and I agree.

Keeps all the files together when listed alphabetically
