# \[PATCH\] video: exynos\_dp: replace link\_status with link\_align to check channel equalization - From: Jingoo Han \ - Date: 2012-09-03 08:50:24 - List: linux-fbdev - Page: https://ratatoskr.run/linux-fbdev/2012/09/13463972 - Thread: https://ratatoskr.run/linux-fbdev/2012/09/13463972/t.md ```text 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.
