This series is the result of a longer debugging session on a phyCORE
STM32MP1 board. It turned out that the 'regulator' command prints the
valid voltage range that a regulator has, but by no means makes sure
that a regulator is set to a voltage inside that range, but instead
happily enables a regulator with whatever default voltage it happens
to have.
On my Phytec board this resulted in the ethernet phy regulator being
enabled with a too low voltage with the effect that ethernet was working
with a very high package loss.
This series fixes that. Another bonus of this series is that the
regulator command now prints the regulators in a tree structure instead
of a plain list.

Sascha Hauer (11):
regulator: rename variable rd to rdev
regulator: merge struct regulator_internal fields into struct
regulator_dev
regulator: introduce regulator logging functions.
regulator: add regulator_get_voltage_internal()
regulator: Add missing cases in regulator_map_voltage()
regulator: stpmic1: add .get_voltage_sel
regulator: stpmic1: add .supply_name
regulator: register regulator as last step in of_regulator_register()
regulator: Set initial voltage
regulator: drop struct regulator_dev::supply_name
regulator: print regulator tree
