Subject: [PATCH] video: exynos_dp: replace link_status with link_align to check channel equalization
Date: Mon, 03 Sep 2012 08:50:24 +0000 [thread overview]
Message-ID: <000001cd89b1$2852e3b0$78f8ab10$%han@samsung.com> (raw)
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.
