This extra clock is needed to access the registers of the AHCI SATA controller used on the Armada 7K/8K SoCs. The ahci drivers was already designed to support up to 5 clocks so there is only need to update the device tree to use it. It was not noticed until now because of wrong assumption in the clock drivers, but as this IP really needs 2 clocks, we had to declare both of them.
Applied on mvebu/dt64 Gregory
