  drm/armada: no need to check parent of remote (2019-06-28 14:50:07 +0100)

----------------------------------------------------------------
Armada DRM updates:
- Fix interlace support.
- use __drm_atomic_helper_plane_reset in overlay reset.
- since the overlay and video planes use essentially the same format
  registers, precompute their values while validating.
- fix a long-standing deficiency with overlay planes and interlace modes
- calculate plane starting address at atomic_check stage rather than
  when we're programming the registers.
- add gamma support.
- ensure mode adjustments made by other components are properly handled
  in the driver and applied to the CRTC-programmed mode.
- add and use register definitions for the "REG4F" register.
- use drm_atomic_helper_shutdown() when tearing down to ensure that the
  hardware is properly shutdown.
- add CRTC-level mode validation to ensure that we don't allow a mode
  that the CRTC-level hardware can not support.
- improve the clocking selection for Armada 510 support.
- move CRTC debugfs files into the crtc-specific directory, using the
  DRM helper to create these files.
- patch from Lubomir Rintel to replace a simple framebuffer.
- use the OF graph walker rather than open-coding this.
- eliminate a useless check for the availability of the remote's parent
  which isn't required.
