Can the DSI TX pin of TDA4VM be pinmux as CSI TX to connect to DS90UB953 to output video?

We use UB953 to connect to DSI TX pin of TDA4VM in our own customized board for outputing video. We use UB960 in another board to get the video.

Thanks.

Hello Hui-Liu,

I think the same pins could be used either as DSI TX output or CSI-TX output. As far as i recollect, there is no pinmux to be setup for these pins. we just need to set correct output mode in CTRLMMR_DPHY_TX0_CTRL register.

Let me double confirm the same.

Hello Hui-Liu,

Confirmed, there is no need to change/set pinmux for DSI, CSITX pins. We would just require to select pin functionality in the CTRLMMR_DPHY_TX0_CTRL register correctly.
