Subject: [Intel-gfx] [PATCH v3 04/19] drm/i915: Introduce AUX_CH_USBCn
Date: Wed, 28 Oct 2020 23:33:08 +0200 [thread overview]
Message-ID: <20201028213323.5423-5-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20201028213323.5423-1-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Just like with the DDIs tgl+ renamed the AUX CHs to reflect
the type of the DDI. Let's add the aliasing enum values for
the type-C AUX CHs.
