[PATCH v8 0/8] i2c-octeon and i2c-thunderx driver

[Jan Glauber <jglauber@cavium.com>]

Hi Wolfram,

this are the remaining patches that implement the ThunderX driver.
I like to send them now even if they might not make 4.7.
After the Octeon parts are merged the ThunderX driver code is
quite straight-forward, as should be the driver split.

Patch #5 - #7 are (final) cleanup patches.

Patches are on-top of next-20160502.

Thanks,
Jan
