Merge tag 'regulator-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator

Pull regulator updates from Mark Brown:
"Quite a quiet release for regulator, the diffstat is dominated by the
I2C migration to probe_new() and the newly added MT6357 driver. We've
just one framework addition and the rest is all new device support,
fixes and cleanups.

The framework addition is an API for requesting all regulators defined
in DT, this isn't great practice but has reasonable applications when
there is generic code handling devices on buses where the bus
specification doesn't include power. The immediate application is MDIO
but I believe there's others, it's another API that'll need an eye
keeping on it for undesirable usage.

Summary:

- An API for requesting all regulators defined in DT

- Conversion of lots of drivers to the I2C probe_new() API

- Support for Mediatek MT6357, Qualcomm PM8550, PMR735a and Richtek
RT6190"

+description: |
+  The RT6190 is 4-Switch BuckBoost controller designed for converting input
