Subject: [Intel-gfx] [PATCH 0/7] drm/i915: Add support for LTTPR non-transparent link training mode
Date: Tue, 22 Sep 2020 15:50:59 +0300	[thread overview]
Message-ID: <20200922125106.30540-1-imre.deak@intel.com> (raw)

Add the drm-core helpers and register definitions required to detect
LTTPRs and perform the link training in non-transparent mode. In i915
switch to non-transparent link training mode if any LTTPR is detected.

Cc: dri-devel@lists.freedesktop.org
