Subject: [PATCH 4/5] drm/connector: Split out orientation quirk detection
Date:   Mon, 10 Jun 2019 21:03:49 -0700
Message-Id: <20190611040350.90064-5-dbasehore@chromium.org>
In-Reply-To: <20190611040350.90064-1-dbasehore@chromium.org>
References: <20190611040350.90064-1-dbasehore@chromium.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This removes the orientation quirk detection from the code to add
an orientation property to a panel. This is used only for legacy x86
systems, yet we'd like to start using this on devicetree systems where
quirk detection like this is not needed.
