I will add the same comment here

Not necessarily, it can change, it used to change across GXBB boards, but
seems to be more coherent across GXL/GXM/G12A ref designs and derivative
boards, but it can still change if the HW designer decides to be creative !

I think VDDQ1_5 is specific to SEI510, will check on the schematics

Yep, will cleanup

I find the hint in the meson-g12a-sei510 regulators patch very good:
Still missing
* VDD_EE (0.8V - PWM controlled)
* VDD_CPU(PWM controlled)
* VDDQ1_5
VDD_EE and VDD_CPU are *probably* going to be very similar across all
boards (Meson8b uses two slightly different PWM regulators on all
boards supported by mainline, but the basic concept is always the
same)
I'm not sure if VDDQ1_5 is specific to the SEI510 board though.

there are two unrelated whitespace changes above.
please clean them up if you have to re-send this for whatever reason
