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 v2 my other series from [0]:
"provide the XTAL clock via OF on Meson8/8b/8m2"

Changes since v1 at [1]:
- fixed the license of the .yaml binding and added Rob's Reviewed-by
- drop unused syscon.h include (spotted by Jerome - thanks)
- drop fast_io from regmap_config and add max_register as suggested
  by Jerome
- dropped original patch #4 "clk: meson: meson8b: add the ddr_pll
  input for the audio clocks" because I could not test that yet (that
  patch was a forward-port from Amlogic's 3.10 BSP kernel)
