This patch series adds ASV (Adaptive Supply Voltage) support
for Exynos SoCs. Previous version can be found at:
https://lore.kernel.org/linux-arm-kernel/20190917181322.GA683@bogus/t/

The first one is a patch for drivers/opp adding support for adjusting
OPP voltage at runtime [1], including my update to also handle OPP min/max
voltage.

The dt-bindings patch has been converted to YAML and needs to be aplied
to Rob's tree as it depends on a patch already applied there
("daa629cdba21 dt-bindings: arm: samsung: Convert Exynos Chipid bindings
to json-schema").

Already applied dts patches were dropped from the series.

The patch set is based on for-next branch,
git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux.git

Tested on Odroid XU3, XU3 Lite, XU4.
