Subject: [PATCH 3/6] drm/panel: simple: Add "no-hpd" delay for Innolux TV123WAM
Date: Mon, 22 Oct 2018 13:46:36 -0700 [thread overview]
Message-ID: <20181022204639.8558-3-dianders@chromium.org> (raw)
In-Reply-To: <20181022204639.8558-1-dianders@chromium.org>
If the HPD signal isn't hooked up to this panel we need a 200 ms
delay. In the datasheet this is shown as the maximum time that HPD
will take to be asserted after power is given to the panel.
