please also add supplies for regulators. Information on supplies
should be easily extractable from the board schematics.
This not only results in a nice tree in debugfs (regulator/regulator_summary)
but also makes sure supplying regulators are not accidentially turned off.
(pwm-supply for pwm-regulators, vin-supply for fixed regulators)

don't create a subnode/bus for regulators. Just add them
regularly. Take a look at all the other boards (like rk3399-firefly,
gru, veyron) for reference.

Same here, no regulator@0 please, just name this one

Thanks and noted your comments above. I will fix them (also include
another comment about eMMC in PATCH 4/6 ) and resend these series soon.
BR.
