TDA4VM: TDA4x DSI interface support UB941 superframe mode?

Part Number: TDA4VM

Hi experts:

We are discussing with customer use TDA4x DSI interface drive 2 1080p@30FPS LCD.

Our UB941 support superframe mode. (https://www.ti.com/lit/ds/symlink/ds90ub941as-q1.pdf)

I believe our DSI interface support superframe mode. but remained some question:

1. TDA4x support symmetric splitting and Asymmetric mode?

2. Default Linux software driver support superframe or we have develop plan for support it?

Best Regards!

    Hi Tao,

    I think this essentially means setting up width to be 2 times the actual width on the input pipe. Then in the application, two frames needs to be merged into a single buffer. 

    From the driver point of view, no change required, application requires to take care of merging two frames.. 

    We have not really tested this feature. But i think from DSI point of view, no change required..  

    Regards,
