Hi Emil,
About the specific usage of overlay for this board + hat, referenced to the following example in kernel:
linux/arch/arm64/boot/dts/freescale/imx8mm-venice-gw73xx-0x-imx219.dtso
That board is connected with imx219 sensor via mipi_csi interface. That patch was accepted in 2022.
So do you think this way is feasible ?
Thanks!
Best regards,
Walker
