From 77666b72260da3a5290471de77e2d2261244db83 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Sun, 27 Oct 2013 21:22:58 +0200 Subject: [PATCH] drm: Use crtc_clock in drm_calc_timestamping_constants() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
