Merge tag 'drm-fixes-2021-10-22' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "Nothing too crazy at the end of the cycle, the kmb modesetting fixes
  are probably a bit large but it's not a major driver, and its fixing
  monitor doesn't turn on type problems.

  Otherwise it's just a few minor patches, one ast regression revert, an
  msm power stability fix.

  ast:
   - fix regression with connector detect

  msm:
   - fix power stability issue

  msxfb:
   - fix crash on unload

  panel:
   - sync fix

  kmb:
   - modesetting fixes"

* tag 'drm-fixes-2021-10-22' of git://anongit.freedesktop.org/drm/drm:
  Revert "drm/ast: Add detect function support"
  drm/kmb: Enable ADV bridge after modeset
  drm/kmb: Corrected typo in handle_lcd_irq
  drm/kmb: Disable change of plane parameters
  drm/kmb: Remove clearing DPHY regs
  drm/kmb: Limit supported mode to 1080p
  drm/kmb: Work around for higher system clock
  drm/panel: ilitek-ili9881c: Fix sync for Feixin K101-IM2BYL02 panel
  drm: mxsfb: Fix NULL pointer dereference crash on unload
  drm/msm/devfreq: Restrict idle clamping to a618 for now
