In the dsi panel example, clock names in the "clock-names"
field have been swapped:
* "pclk" (peripheral clock) is <&rcc 1 CLK_F469_DSI> on stm32f4
* "ref" (dsi phy pll ref clock) is <&clk_hse> on stm32f4

Yes.
Please resend both patches and I'll apply.

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 :-)

There is no way to tell they are reversed because pclk is not even
documented. Please fix that too.
