dt-bindings: clock: add the Amlogic Meson8 DDR clock controller binding 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.
