[PATCH v4 0/3] i2c: mv64xxx: Fix clock resource for Armada 7K/8K

[Gregory CLEMENT]

Hi,

This short series fixes the way the clocks are used for the mv64xxx
controller embedded in the Marvell Armada 7K/8K SoCs. On these SoCs a
second one is needed in order to clock the registers. It was not
noticed until now because we relied on the bootloader and also because
the clock driver was wrong.

Thanks to this fix, it would be possible to fix the clock driver
without introducing a regression.

The first patch is just a small cleanup found when I wrote the main
patch.

The last patch is not related to the series but as Wolfram to have a
maintainer for this driver I added the patch here.

Thanks,

Gregory
