Subject: [PATCH v2 3/6] drm/panel: simple: Add "no-hpd" delay for Innolux TV123WAM
Date: Thu, 25 Oct 2018 15:21:31 -0700 [thread overview]
Message-ID: <20181025222134.174583-3-dianders@chromium.org> (raw)
In-Reply-To: <20181025222134.174583-1-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.
Signed-off-by: Douglas Anderson <dianders@chromium.org>

Changes in v2:
- Use "hpd_absent_delay" property instead of a bool + prepare delay
