clk: clock driver for the Marvell Armada AP806

Michael, Stephen,

Here is a new version of the clock driver and its DT binding for the Marvell Armada AP806. As you will see, there is no longer any reference to the DFX Server and changes in the clock tree compared to the v2. This is due to the fact that the HW has changed from this point of view between the test chips and the final revision, and this new version aims at supporting only the final revision.

We therefore have a very simple DT binding, with one single node that covers the entire "system controller" registers, associated to one driver that provides the clocks. This system controller will later be used to support other features such as pin-muxing, but for now we only support the clocks aspects of it.

Please let me know if this approach works for you.

Note that this patch series is based on clk-net, because I wanted to avoid introducing a new use of CLK_IS_ROOT. To do this, I needed the patches currently in clk-next that remove the need for CLK_IS_ROOT.

Thanks!

Thomas
