[PATCH v2 00/11] Improve cp110 clk support on Marvell Armada 7K/8K

Hi ,

Please do not apply this version. I was just pointed that I misread the
documentation and that the GOP clock are really also used by the
SD/eMMC.

So I am about sending a new version of the series removing the 2 first
patchs and fixing the patch 5.
