[U-Boot] [PATCH v2 0/3] ARM: meson: Use syscon/regmap for clock driver

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!

Changes since v1:
- rebased on the "Amlogic Meson cleanup for AXG SoC support" patchset from Neil

Loic Devulder (3):
  ARM: meson: Add regmap support for clock driver
  ARM: meson: Enable syscon on all supported boards
  ARM: dts: meson: Update dts files from Linux v4.19
