[PATCH v3 0/7] arm64: dts: meson: add more GX soundcards

[PATCH v3 0/7] arm64: dts: meson: add more GX soundcards

[Christian Hewitt]

This series adds basic support for LPCM audio over HDMI and S/PDIF
to GXBB/GXL/GXM devices that I own and have tested with. Audio can
be extended in the future (some devices have DACs and headphone
hardware to connect) but this gets the basics working.

Changes from v2
- Drop p200/p201/p212-s905x/vega-s95 changes
- Add khadas-vim(1)

Changes from v1
- Drop nexbox-a1 and rbox-pro
