Subject: [RFC resend 1/4] dt-bindings: display: mediatek: add drm binding
Date: Thu, 19 Oct 2017 13:26:07 +0200 [thread overview]
Message-ID: <20171019112610.13645-2-mbrugger@suse.com> (raw)
In-Reply-To: <20171019112610.13645-1-mbrugger@suse.com>
DRM subysystem and clock driver shared the same compatible mmsys.
This stopped does not work, as only the first driver for a compatible
gets probed. We change the comaptible to the new DRM identifier to fix
this.
