From e75478bbd79f4d1694522f1dec7a6cb60c90d3b1 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Mon, 3 Sep 2012 17:50:24 +0900 Subject: [PATCH] video: exynos_dp: replace link_status with link_align to check channel equalization To check channel equalization, the value of LANE_ALIGN_STATUS_UPDATED is necessary in exynos_dp_channel_eq_ok(). Also, link_align includes this value. However, link_status does not include this value, so it makes the problem that channel equalization is failed during link training.
