Subject[PATCH v3 1/3] ARM: dts: vf-colibri: remove regulator container node
Date
Drop the fake simple-bus container 'regulators' and put the
regulators directly under the root node. This also makes the
artificial 'reg' properties superfluous. While at it, remove
the unnecessary regulator-always-on property and name the
regulators according to schematics.

Signed-off-by: Stefan Agner <stefan@agner.ch>
---
Changes since v2:
- remove regulator-always-on

Changes since v1:
- rename regulators according to schematics
- drop sys prefix
