Commit 9dcf8a58 authored by Linus Torvalds's avatar Linus Torvalds

Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "A bunch of radeon displayport mode setting fixes, and some misc i915
  fixes.

  There is one revert, the MST audio code in i915 was causing some
  oopses, so we've decided just to drop it until next kernel when we can
  fix it properly"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/amdgpu: fix DP mode validation
  drm/radeon: fix DP mode validation
  drm/i915: Bail out of pipe config compute loop on LPT
  drm/radeon: fix PLL sharing on DCE6.1 (v2)
  drm/radeon: fix DP link training issue with second 4K monitor
  Revert "drm/i915: start adding dp mst audio"
  drm/i915/bdw: Add missing delay during L3 SQC credit programming
  drm/i915/lvds: separate border enable readout from panel fitter
  drm/i915: Update CDCLK_FREQ register on BDW after changing cdclk frequency
