Subject: [PATCH 2/3] drm: rockchip: hdmi: allow any clock that is within the range
Date: Mon, 21 Sep 2020 20:18:02 +0200 [thread overview]
Message-ID: <20200921181803.1160-3-vicencb@gmail.com> (raw)
In-Reply-To: <20200921181803.1160-1-vicencb@gmail.com>
For a video mode to work it suffices that the available bandwidth is
large enough. There is no need to have an exact match.
This greatly expands the list of supported monitors.
