Is "leez" really the vendor?
Part of me would assume something like
lenovo,leez-p710

So please clarify :-)
And also please make sure the decided vendor is part of the vendor-prefixes
binding in Documentation/devicestree/bindings/vendor-prefixes.yaml

same comment as above, so maybe:
model = "Lenovo Leez RK3399 P710";
compatible = "lenovo,leez-p710", "rockchip,rk3399";

In general, please model an actual regulator-tree and do not copy the
unspecific Rockchip vendor tree. These unconnected regulators are a very
good indicator that the real power-tree got ignored (missing vin-supply here)

I found schematics on https://github.com/leezsbc/resources/wiki/Leez-P710:
链接: https://pan.baidu.com/s/1NPWbuI5csT4zftKUCnRs7g
提取码: rvrh

and there the power-tree is described in a complete way.

regulator/regulator_summaray in the kernels debugfs should
show a nice tree structure starting from the dc-adapter input.

Also please use names matching the supply names from the schematics.

Same for pinctrl names, please use names as used in the board schematics.

can this also use the internal i2c inside the dw-hdmi?
