[PATCH v4 0/2] i2c: pxa: fix I2C communication on Armada 3700

[Gabor Juhos]

There is a long standing bug which causes I2C communication not to
work on the Armada 3700 based boards. The first patch in the series
fixes that regression. The second patch improves recovery to make it
more robust which helps to avoid communication problems with certain
SFP modules.
