Subject: [RESEND PATCH v4 1/7] drm/bridge: ps8640: Get the EDID from eDP control
Date: Mon, 15 Jun 2020 22:31:02 +0200	[thread overview]
Message-ID: <20200615203108.786083-2-enric.balletbo@collabora.com> (raw)
In-Reply-To: <20200615203108.786083-1-enric.balletbo@collabora.com>

The PS8640 DSI-to-eDP bridge can retrieve the EDID, so implement the
.get_edid callback and set the flag to indicate the core to use it.
