Subject: [PATCH] drm: Add FEC registers for LT-tunable repeaters
Date: Thu,  5 Dec 2019 08:58:56 -0500	[thread overview]
Message-ID: <20191205135856.232784-1-Rodrigo.Siqueira@amd.com> (raw)

FEC is supported since DP 1.4, and it was expanded for LT-tunable in DP
1.4a. This commit adds the address registers for
FEC_ERROR_COUNT_PHY_REPEATER1 and FEC_CAPABILITY_PHY_REPEATER1.
