[Barnabás Czémán]

Redmi 5A was made by wingtech like Redmi 4A (rolex) and Redmi GO (tiare).

unnecessary code duplications.

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation
If you cannot find a name matching your device, please check in kernel
sources for similar cases or you can grow the spec (via pull request to
DT spec repo).

I see the Go has some differences in regulator configuration.

Does the 4A's one match the existing 5A?

Yes they are same, l22 is vana l23 is vdig for camera sensor.
riva and rolex is using 2.8v for vana and 1.2v for vdig.
tiare is using 2.85v for vana and 1.2 v for vdig so l22 min-voltage also 
should be increased
but l23 max-voltage increase is unnecessary, there is no reason to keep 
downstream value there.

Here is some proof

FWIW it's easiest to work with decompiled DTs, as the include chains are
often very complex. You can then throw them into ./scripts/dtx_diff or
similar

[PATCH v2 7/7] arm64: dts: qcom: Add Redmi Go

[Barnabás Czémán]

Redmi Go (tiare) is like Redmi 5A with small differences like charging,
fuel gauge and different speaker codec.
