[PATCH 0/6] add the DDR clock controller on Meson8 and Meson8b

[Martin Blumenstingl]

Meson8 and Meson8b SoCs embed a DDR clock controller in their MMCBUS
registers. This series:
- adds support for this DDR clock controller (patches 0 and 1)
- wires up the DDR PLL as input for two audio clocks (patches 2 and 3)
- adds the DDR clock controller to meson8.dtsi and meson8b.dtsi

Special thanks go out to Alexandre Mergnat for switching the Amlogic
clock drivers over to parent_hws and parent_data. That made this series
a lot easier for me!

This series depends on my other series from [0]:
"provide the XTAL clock via OF on Meson8/8b/8m2"
