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.
I tried to keep compatibility with the old behaviour, if needed.
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!
