[PATCH] dt-bindings: Drop unnecessary *-supply schemas properties

STALE2105d LANDED

From: Rob Herring <robh@kernel.org>
Date: 2020-12-21 23:48:00
Also in: dri-devel, linux-devicetree, linux-iio, linux-media, lkml
Subsystem: analog devices inc iio drivers, drm driver for parade ps8640 bridge chip, drm drivers, drm drivers and misc gpu patches, drm drivers for bridge chips, iio subsystem and drivers, input (keyboard, mouse, joystick, touchscreen) drivers, max9286 quad gmsl deserializer driver, media input infrastructure (v4l/dvb), mipi ccs, smia and smia++ image sensor driver, multifunction devices (mfd), open firmware and flattened device tree bindings, sony imx214 sensor driver, sony imx274 sensor driver, the rest, voltage and current regulator framework · Maintainers: Nuno Sá, Michael Hennerich, David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Andrzej Hajda, Neil Armstrong, Robert Foss, Jonathan Cameron, Dmitry Torokhov, Jacopo Mondi, Kieran Bingham, Laurent Pinchart, Niklas Söderlund, Mauro Carvalho Chehab, Sakari Ailus, Lee Jones, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Ricardo Ribalda, Leon Luo, Linus Torvalds, Liam Girdwood, Mark Brown

Landed in mainline as 9bfaf9c729a9 on 2020-12-23.

*-supply properties are always a single phandle, so binding schemas
don't need a type $ref nor 'maxItems'.

A meta-schema check for this is pending once these existing cases are
fixed.
