Subject: [PATCH 02/15] drm/atomic: Reject attempts to use multiple rotation angles at once
Date: Mon, 26 Sep 2016 19:30:47 +0300 [thread overview]
Message-ID: <1474907460-10717-3-git-send-email-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <1474907460-10717-1-git-send-email-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
The rotation property should only accept exactly one rotation angle
at once. Let's reject attempts to set none or multiple angles.
Testcase: igt/kms_rotation_crc/bad-rotation
