Subject: [PATCH v4 03/16] drm: bridge: analogix/dp: split exynos dp driver to bridge dir
Date: Tue,  1 Sep 2015 13:49:58 +0800
Message-Id: <1441086598-24995-1-git-send-email-ykk@rock-chips.com>
X-Mailer: git-send-email 1.9.1

Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

Split the dp core driver from exynos directory to bridge
directory, and rename the core driver to analogix_dp_*,
leave the platform code to analogix_dp-exynos.

Signed-off-by: Yakir Yang <ykk@rock-chips.com>
---
Changes in v4:
- Take Rob suggest, update "analogix,hpd-gpios" to "hpd-gpios" DT propery.
- Take Jingoo suggest, rename "analogix_dp-exynos.c" file name to "exynos_dp.c"
- Take Archit suggest, create a separate folder for analogix code in bridge/

Changes in v3:
- Take Thierry Reding suggest, move exynos's video_timing code
  to analogix_dp-exynos platform driver, add get_modes method
  to struct analogix_dp_plat_data.
- Take Heiko suggest, rename some "samsung*" dts propery to "analogix*".

Changes in v2:
- Take Jingoo Han suggest, remove new copyright
- Fix compiled failed dut to analogix_dp_device misspell
