Merge tag 'drm-fixes-2019-02-15-1' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "Usual pull request, little larger than I'd like but nothing too
  strange in it. Willy found an bug in the lease ioctl calculations, but
  it's a drm master only ioctl which makes it harder to mess with.

 i915:
   - combo phy programming fix
   - opregion version check fix for VBT RVDA lookup
   - gem mmap ioctl race fix
   - fbdev hpd during suspend fix
   - array size bounds check fix in pmu

  amdgpu:
   - Vega20 psp fix
   - Add vrr range to debugfs for freesync debugging

  sched:
   - Scheduler race fix

  vkms:
   - license header fixups

  imx:
   - Fix CSI register offsets for i.MX51 and i.MX53.
   - Fix delayed page flip completion events on i.MX6QP due to
     unexpected behaviour of the PRE when issuing NOP buffer updates to
     the same buffer address.
   - Stop throwing errors for plane updates on disabled CRTCs when a
     userspace process is killed while a plane update is pending.
   - Add missing of_node_put cleanup in imx_ldb_bind"

* tag 'drm-fixes-2019-02-15-1' of git://anongit.freedesktop.org/drm/drm:

  drm/i915/opregion: rvda is relative from opregion base in opregion 2.1+
  drm/i915/opregion: fix version check
  drm/i915: Prevent a race during I915_GEM_MMAP ioctl with WC set
  drm/i915: Block fbdev HPD processing during suspend
  drm/i915/pmu: Fix enable count array size and bounds checking
  drm/i915/cnl: Fix CNL macros for Voltage Swing programming
  drm/i915/icl: combo port vswing programming changes per BSPEC
  drm/vkms: Fix license inconsistent
  drm/amd/display: Expose connector VRR range via debugfs
  drm/sched: Always trace the dependencies we wait on, to fix a race.
  gpu: ipu-v3: pre: don't trigger update if buffer address doesn't change
  gpu: ipu-v3: Fix CSI offsets for imx53
  drm/imx: imx-ldb: add missing of_node_puts
