Hello Alexandre,

Thanks for the series.

Would it be possible to add the support in
arch/arm64/boot/dts/mediatek/mt8183.dtsi ?

Given the driver is stateful it should be possible
for anyone to test it with standard userspace
such as GStreamer.

Is it possible for the firmware to be pushed to linux-firmware ?

Thanks,
Ezequiel
