From 59f031c04d4761dceb5e75300aa3ad9d1d0ae4a4 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 24 Sep 2021 09:16:14 +0200 Subject: dt-bindings: mfd: Convert X-Powers AC100 binding to a schema The X-Powers AC100 hybrid devices are supported by Linux thanks to its device tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that driver over to a YAML schema.
