Subject: [PATCH v3 03/14] drm: bridge: analogix_dp: split exynos dp driver to bridge dir
Date: Wed, 19 Aug 2015 09:50:02 -0500
Message-Id: <1439995802-18210-1-git-send-email-ykk@rock-chips.com>
In-Reply-To: <1439995728-18046-1-git-send-email-ykk@rock-chips.com>

Lines: 5658

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 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
