It's very probable all the STB boxes uses the same scheme, so it'll be safe to add the analog audio output here exactly like libretech-cc. Neil

Add initial audio support limited to HDMI i2s. Signed-off-by: Christian Hewitt <christianshewitt@gmail.com> --- The P212 dts is widely used with Android box devices that follow the reference design. The real P212 development board probably has many more audio capabilities, but as a minimum we can enable HDMI output and help box users too. .../boot/dts/amlogic/meson-gxl-s905x-p212.dts | 40 +++++++++++++++++++ 1 file changed, 40 insertions(+)
