Merge tag 'drm-intel-fixes-2017-10-11' of git://anongit.freedesktop.org/drm/drm-intel into drm-fixes
drm/i915 fixes for 4.14-rc5: Three fixes for stable: - Use crtc_state_is_legacy_gamma in intel_color_check (Maarten) - Read timings from the correct transcoder (Ville). - Fix HDMI on BSW (Jani). Other fixes: - eDP fixes (Manasi) - Silence compiler warnings (Chris) - Order two completing nop_submit_request (Chris) * tag 'drm-intel-fixes-2017-10-11' of git://anongit.freedesktop.org/drm/drm-intel: drm/i915/bios: parse DDI ports also for CHV for HDMI DDC pin and DP AUX channel drm/i915: Read timings from the correct transcoder in intel_crtc_mode_get() drm/i915: Order two completing nop_submit_request drm/i915: Silence compiler warning for hsw_power_well_enable() drm/i915: Use crtc_state_is_legacy_gamma in intel_color_check drm/i915/edp: Increase the T12 delay quirk to 1300ms drm/i915/edp: Get the Panel Power Off timestamp after panel is off
