Hello, I'll use ADV7671A for OSD insertion on HDMI 2.1b TMDS(4k60p).
For the SoC for controlling ADV7671A via "SPI", I'll use linux base SoC.
But unfortunately I can't find SPI protocol for ADV7671A at driver level in the datasheet, so I can't implement SPI driver on linux.
So let me know the protocol of SPI for the interface of ADV7671A.
I belong to the company of HDMI/HDCP adopter.
Best Regards,
