[PATCH v2 0/2] ARM64: dts: meson-gx: Enable CEC

[Neil Armstrong]

This patchset enables :
 - Update the AO domain clkc to new bindings
 - AO CEC Controller linked with the HDMI controller all HDMI supported boards

This patchset depends on the clock bindings posted in [1].

Changes since v1 at [2]:
 - Update to new bindings introduces in [3]
 - Added cec to wetek-play2, khadas-vim and libretech-cc

[PATCH v2 1/2] ARM64: dts: meson-gx: update AO clkc to new bindings

[Neil Armstrong]

The AO clkc needs to be updated to new bindings with an system control parent
node and moving the clkc node as subnode.

Also adds the SoC specific compatible following the bindings requirements.
