Remove address/size-cells properties for "mdss_dsi1" node.
I cannot parse it. Address/size cells never have ranges or children.
They cannot have. These are uint32 properties.
Pls help to comment on the revised commit message. Every time I write a

others can understand me correctly as well. Feel free to let us know if
it is not readable to you. It will help us as non-English native developers.

I disagreed with the patch before. You resubmit it without really
addressing my concerns.
I am not sure if this is correct fix and I want to fix all of such
errors (there are multiple of them) in the same way. Feel free to
propose common solution based on arguments.
Per my understanding, "qcom,mdss-dsi-ctrl" driver node like "mdss_dsi1"
don't need to have address/size-cells properties.
Just because dtc says so? And what about bindings?
I don't find any reason why "qcom,mdss-dsi-ctrl" driver node need to
have address/size-cells properties. Document Bindings should also be fixed.
Feel free to let us know whether there is different idea of
"address/size-cells" needed for the "qcom,mdss-dsi-ctrl" driver node.
The bindings expressed that idea. If the binding is incorrect, fix the
binding and the DTS. If the binding is correct, provide rationale why it
somehow does not apply here etc.
Our plan is to fix the bindings as well.
In case you have missed the question, I just re-place it here:
While there are about 22 different soc dtsi and it's document binding
files needed to be fixed. Shall we fix it for all qcom related soc usage
in one patch, or we'd better to split into different patches according
to soc specifically?
Best regards,
Krzysztof
