Subject: [PATCH 3/3] dt-bindings: regulator: Fix yaml verification for fixed-regulator schema

From: Alexandre Torgue <[email-masked]>
Date: Mon, 7 Oct 2019 12:25:52 +0200

This commit fixes an issue seen during yaml check ("make dt_binding_check").
Compatible didn't seem to be seen as a string.

Reported issue:
"properties:compatible:enum:0: {'const': 'regulator-fixed'}
is not of type 'string'"
And
"properties:compatible:enum:1: {'const': 'regulator-fixed-clock'}
is not of type 'string'"

Fixes: 9c86d003d620 ("dt-bindings: regulator: add regulator-fixed-clock binding")
