From 704330615bfdb8ec9e21cabfd462e785007593ba Mon Sep 17 00:00:00 2001 From: Yakir Yang Date: Mon, 15 Feb 2016 19:10:26 +0800 Subject: dt-bindings: add document for analogix display port driver Analogix dp driver is split from exynos dp driver, so we just make an copy of exynos_dp.txt, and then simplify exynos_dp.txt Beside update some exynos dtsi file with the latest change according to the devicetree binding documents.
