Subject: [PATCH 2/2] drm/tegra: hub: Register child devices
Date: Fri, 12 Jun 2020 17:01:00 +0200	[thread overview]
Message-ID: <20200612150100.2419935-2-thierry.reding@gmail.com> (raw)
In-Reply-To: <20200612150100.2419935-1-thierry.reding-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

In order to remove the dependency on the simple-bus compatible string,
which causes the OF driver core to register all child devices, make the
display-hub driver explicitly register the display controller children.
