[PATCH 0/7] arm64: dts: meson: add internal audio DAC support

[PATCH 0/7] arm64: dts: meson: add internal audio DAC support

[Jerome Brunet]

This patchset adds support for the internal audio DAC found on the gxl,
g12 and sm1 SoC family.

It was mainly tested on the gxl libretech-cc and g12a u200.

/!\
This series (patches 1 in particular) depends on this reset binding [0].
Philipp has provided an immutable with it here [1]
