Merge tag 'drm-next-2019-09-27' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "Fixes built up over the past 1.5 weeks or so, it's two weeks of
  amdgpu, some core cleanups and some panfrost fixes. I also finally
  figured out why my desktop was slow to do a bunch of stuff (someone
  gave it an IPv6 address which can't reach anything!).

  core:
   - Some cleanups and fixes in the self-refresh helpers
   - Some cleanups and fixes in the atomic helpers

  amdgpu:
   - Fix a 64 bit divide
   - Prevent a memory leak in a failure case in dc
   - Load proper gfx firmware on navi14 variants
   - Add more navi12 and navi14 PCI ids
   - Misc fixes for renoir
   - Fix bandwidth issues with multiple displays on vega20
   - Support for Dali
   - Fix a possible oops with KFD on hawaii
   - Fix for backlight level after resume on some APUs
   - Other misc fixes

  panfrost:
   - Multiple panfrost fixes for regulator support and page fault
     handling"
