[PATCH v2 0/3] arm64: dts: meson: add more G12/SM1 soundcards

[PATCH v2 0/3] arm64: dts: meson: add more G12/SM1 soundcards

[Christian Hewitt]

This series adds basic support for LPCM audio over HDMI interfaces
to the Khadas VIM3L (reusing the same config as the VIM3) and the
HardKernel ODROID-C4 devices, and HDMI + S/PDIF on U200 reference
board (reusing the config from the X96-Max box), I'm sure support
can be extended to include other hardware but this gets the HDMI
port working as a minimum capability. I have tested with VIM3L/C4
devices and a no-name S905X2 box.

v2 changes - include u200

Nack.

#1. Same comment as before on spdifout B and SPDIF HDMI input.
#2. the u200 is a special reference device with 2 onboards codecs,
    external connector for audio daugther boards and internal codec.
    I don't see another board using that configuration, which would make
    them incompatible
#3. TDM B is a bad choice on this board as it connected to one of the
    i2s codecs of the board, which won't take 4 lines ine.
