Subject: [PATCH] dt-bindings: pinctrl: stm32: Fix 'st,syscfg' schema

From: Rob Herring <[email-masked]>
Date: Tue, 13 Aug 2019 14:55:28 -0600

The proper way to add additional contraints to an existing json-schema
is using 'allOf' to reference the base schema. Using just '$ref' doesn't
work. Fix this for the 'st,syscfg' property.

I've got some other fixes queued up and can take this via the DT tree.
