Subject: [PATCH 3/3] arm64: dts: rk3399-rock-pi-4c: Enable Display Port
Date: Sat, 5 Sep 2020 00:48:30 +0530 [thread overview]
Message-ID: <20200904191830.387296-4-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20200904191830.387296-1-jagan@amarulasolutions.com>
Enable Display Port on ROCK Pi 4C board.
Unlike, other RK3399 platforms with accessing DP Altmode
via Type-C connector, the display Port on ROCK Pi 4C is
accessible via physical display port connector by means
of Type-C Virtual PD extcon configuration.
Enable support for it.
