Subject: [PATCH v2 2/3] drm/bridge: ti-sn65dsi86: Implement bridge->mode_valid()
Date: Mon, 20 Sep 2021 15:57:59 -0700 [thread overview]
Message-ID: <20210920225801.227211-3-robdclark@gmail.com> (raw)
In-Reply-To: <20210920225801.227211-1-robdclark@gmail.com>
From: Rob Clark <robdclark@chromium.org>
For the brave new world of bridges not creating their own connectors, we
need to implement the max clock limitation via bridge->mode_valid()
instead of connector->mode_valid().
v2: Drop unneeded connector->mode_valid()
