drm-misc-next for v5.3:

UAPI Changes:
- Give each dma-buf their own inode, add DMA_BUF_SET_NAME ioctl and a show_fdinfo handler.

Cross-subsystem Changes:
- Pull in the topic/remove-fbcon-notifiers branch:
  * remove fbdev notifier usage for fbcon, as prep work to clean up the fbcon locking
  * assorted locking checks in vt/console code
  * assorted notifier and cleanups in fbdev and backlight code

Core Changes:
- Make drm_debugfs_create_files() never fail.
- add debug print to update_vblank_count.
- Add DP_DPCD_QUIRK_NO_SINK_COUNT quirk.
- Add todo item for drm_gem_objects.
- Unexport drm_gem_(un)pin/v(un)map.
- Document struct drm_cmdline_mode.
- Rewrite the command handler for mode names, and add support to specify
  rotation, reflection and overscan. With a new selftest! :)
- Fixes to drm/client for improving rotation support, and fixing variable scope.
- Small fixes to self refresh helper.

Driver Changes:
- Add rockchip RK3328 support.
- Assorted driver fixes to rockchip, vc4, rcar-du, vkms.
- Expose panfrost performance counters through unstable ioctl's, hidden
  behind a module parameter.
- Enumerate CRC sources list in vkms.
- Add a basic kms driver for the Ingenic JZ47xx SoC, which will be expanded
  soon with more advanced features.
- Suspend/resume fix for stm.
