Could you please change this to "qcom,msm8953-mdp5", "qcom,mdp5".
This would be the first dtsi using the two compatibles then, correct? Are there
any plans to adjust other SoCs?
Yes, this is a long-going plan. Having just "qcom,mdp5" doesn't allow
switching between mdp5 and dpu1 drivers. Thus I'd ask to add per-SoC
compat strings.
It's up to you (and Rob/Krzysztof) whether to leave just one compat
string or have both of them: a per-soc one and a generic one.

Let's probably use a generic name 'phy' here and for dsi1_phy.
Here also, the bindings examples all use dsi-phy@, are there any plans to
change that and adjust other dtsi files?
Yes, sc7280 already uses phy@ for both DSI and eDP PHYs.
The rest looks good to me.
Thanks!
