[PATCH v2 0/6] arm64: meson: add libretech-pc support

Add libretech PC platform support. This platform comes in 2 variants,
one with the s905d and the other s912.

While working on these boards, I've found a problem related the mmc
clock. In some cases, the ROM code will leave the mmc clocks in such
a weird state that any access to the mmc controller would lock the
device.

Making sure the MMC clocks are properly reset and enabled is enough
to solve the problem.

I have also synced all amlogic supported dts. Since I had to update
the gx dsti files, it made sense to update the dts as well. This is
done to keep things coherent even if it is not the original purpose
of this series.

Changes since v1:
 - Split dt sync, libretech-pc import and config addition.
 - Rebase on master

Jerome Brunet (6):
  dt-bindings: leds: import common led bindings from linux v5.5
  mmc: meson-gx: enable input clocks
  clk: meson: reset mmc clock on probe
  arm64: dts: meson: sync dt and bindings from v5.6-rc2
  arm64: dts: meson: import libretech-pc from linux v5.6-rc2
  arm64: dts: meson: add libretech-pc support
