Many thanks for your review.

pclk is already described in the generic part 
(Documentation/devicetree/bindings/display/bridge/dw_mipi_dsi.txt).

In st,stm32-ltdc.txt (specific part), I have documented: "For all 
mandatory properties & nodes, please refer to the related documentation 
in [5]".

Do you think it is clear enough?

Many thanks,
Philippe :-)
