Subject: [Intel-gfx] [PATCH 02/13] drm/i915: Move TRANS_DDI_FUNC_CTL2 programming where it belongs
Date: Fri, 13 Mar 2020 18:48:20 +0200 [thread overview]
Message-ID: <20200313164831.5980-3-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20200313164831.5980-1-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
This port sync enable/disable stuff is misplaced. It's just another step
of the normal TRANS_DDI_FUNC_CTL enable. Move it to its natural place.
