UAPI Changes:

Cross-subsystem Changes:
- Convert panel-dsi-cm and ingenic bindings to YAML.
- Add lockdep annotations for dma-fence. \o/
- Describe why indefinite fences are a bad idea
- Update binding for rocktech jh057n00900.

Core Changes:
- Add vblank workers.
- Use spin_(un)lock_irq instead of the irqsave/restore variants in crtc code.
- Add managed vram helpers.
- Convert more logging to drm functions.
- Replace more http links with https in core and drivers.
- Cleanup to ttm iomem functions and implementation.
- Remove TTM CMA memtype as it doesn't work correctly.
- Remove TTM_MEMTYPE_FLAG_MAPPABLE for many drivers that have no
  unmappable memory resources.

Driver Changes:
- Add CRC support to nouveau, using the new vblank workers.
- Dithering and atomic state fix for nouveau.
- Fixes for Frida FRD350H54004 panel.
- Add support for OSD mode (sprite planes), IPU (scaling) and multiple
  panels/bridges to ingenic.
- Use managed vram helpers in ast.
- Assorted small fixes to ingenic, i810, mxsfb.
- Remove optional unused ttm dummy functions.
