nit: 'dts' at the end is redundant, the prefixes make it clear that this
is about DT entries.

Also the message isn't really concise. The main entries for the DSI
controller and the PHY are in sc7180.dtsi. I would suggest to drop
any mentions of DSI controller and PHYs, and just say something like
'Add nodes for IDP display'. In the body you could mention that the
display is the Visionox RM69299.

Changes in v1 is pointless, it's the first patch

To get the display actually to work you also need this:

        status = "okay";
 };

+&mdp {
+       status = "okay";
+};
+
+&mdss {
+       status = "okay";
+};
+
 &qspi {
        status = "okay";
        pinctrl-names = "default";

Maybe just add this to this patch?

ping

the display driver landed in drm-misc, but this patch still needs a
respin.
