DRA712: EVM display output definition

Part Number: DRA712


Team, please review and answer my customer question below:

 

 

 

We've been reviewing the display panel configuration for the EVM in the device tree. The device tree being used for the EVM we have is the dra7x-evm-lcd-auo-g101evn01.0.dtsi

 

Now we got confused on trying to understand how the actual dpi output is selected (if it is) in the DTS because of the following:

- The EVM schematic states that the main display panel is connected to the VOUT2 while an optional FPD link is available at VOUT3.

- In the DTS the port config for the DSS are:

     0 for the main display (it does not set 'reg = <x>' so its assumed 0).

     2 for the FPD display.

 

Is this "reg = <xxx>" definition the one defining the SoC output?  It doesn't seem so ( 0 = VOUT2  &  2 = VOUT3 ??)

 

What are we missing?
