This patch series modifies the meson clock driver to use syscon/regmap like the Linux kernel does. It is needed if we want to share the same DTS files with the Linux kernel, as last changes in clock-controller break U-Boot.
These patches also update all meson DTS files to last versions from Linux kernel v4.19.
It was successfully tested on kvim, kvim2 and libretech-cc, both with the old and new DTS files. I don't have any p212, nanopi-k2 nor odroid-c2 boards to test with. As kvim and libretech-cc boards share a lot with p212 I don't expect any issue with that board, but if someone is able to test on nanopo-k2 and odroid-c2 it could be great :-)
I opened this patch series as a RFC, as it's not a tricky part (for me!) and pretty new to me, so any feedback are welcome and wanted!
