Subject: [PATCH v4 07/11] drm/sun4i: Ignore the generic connectors for components
Date: Sat, 27 May 2017 18:09:32 +0200 [thread overview]
Message-ID: <5b34efbc6a9453e845d60170507958df30f76f33.1495900658.git-series.maxime.ripard@free-electrons.com> (raw)
In-Reply-To: <cover.c61cbe60123a4aeb24f255bca7927218dda6283e.1495900658.git-series.maxime.ripard@free-electrons.com>
In-Reply-To: <cover.c61cbe60123a4aeb24f255bca7927218dda6283e.1495900658.git-series.maxime.ripard@free-electrons.com>
The generic connectors such as hdmi-connector doesn't have any driver in,
so if they are added to the component list, we will be waiting forever for
a non-existing driver to probe.
Add a list of the connectors we want to ignore when building our component
list.
