> Amlogic Meson8, Meson8b and Meson8m2 SoCs have a DDR clock controller in
> the MMCBUS registers. There is no public documentation on this, but the
> GPL u-boot sources from the Amlogic BSP show that:
> - it uses the same XTAL input as the main clock controller
> - it contains a PLL which seems to be implemented just like the other
>   PLLs in this SoC
> - there is a power-of-two PLL post-divider
> 
> Add the documentation and header file for this DDR clock controller.
