A few nits below about trying to keep the sort ordering right in this
file. I'm not an expert on device tree properties for display, but
other than these nits things here look good to me.
NOTE also that I'd probably put all 3 of your recent patches in a
3-part series since they all depend on each other, don't they? AKA
I'd to see next time:
[PATCH v4 1/3] arm64: dts: qcom: sdm845: Add dpu to sdm845 dts file
[PATCH v4 2/3] arm64: dts: sdm845: Add dsi pinctrl nodes
[PATCH v4 3/3] arm64: dts: sdm845: Add display nodes to MTP dts
...you can call them all v4 just to make it easier to track...

Generally includes should have < includes above " includes.
...also: please rebase atop Andy's tree. Then you'll have the line:
#include <dt-bindings/regulator/qcom,rpmh-regulator.h>
..."gpio" is alphabetically before "regulator" so your include should
be _above_ that one.

Please keep these nodes sorted alphabetically even if it means you
don't keep all the display nodes together. Thus "mdss" and "mdss_mdp"
should be below "i2c10" and above "qupv3_id_1".

These two things should sorted alphabetically in the "PINCTRL -
additions to nodes defined in sdm845.dtsi" section. So please place
them both above the "qup_i2c10_default" node.
