Subject: [PATCH 11/13] drm/i915: Document a few pre-skl primary plane platform dependencies
Date: Thu, 16 May 2024 16:56:20 +0300	[thread overview]
Message-ID: <20240516135622.3498-12-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20240516135622.3498-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Add some notes indicatign which plane registers/bits are
valid for which platforms.
