Subject: [PATCH 08/14] drm: Use crtc_clock in drm_calc_timestamping_constants()
Date: Tue, 29 Oct 2013 20:06:12 +0200 [thread overview]
Message-ID: <1383069978-12476-9-git-send-email-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <1383069978-12476-1-git-send-email-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
drm_calc_timestamping_constants() computes the pixel/line/frame
durations based on the crtc_ timing values. The corresponding pixel
clock is in mode->crtc_clock, so we need to use that instead of
mode->clock.
This should fix drm_calc_timestamping_constants() for frame packing
stereo modes.
