Merge tag 'drm-misc-next-2020-01-02' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v5.6:

UAPI Changes:
- Commandline parser: Add support for panel orientation, and per-mode options.
- Fix IOCTL naming for dma-buf heaps.

Cross-subsystem Changes:
- Rename DMA_HEAP_IOC_ALLOC to DMA_HEAP_IOCTL_ALLOC before it becomes abi.
- Change DMA-BUF system-heap's name to system.
- Fix leak in error handling in dma_heap_ioctl(), and make a symbol static.
- Fix udma-buf cpu access.
- Fix ti devicetree bindings.

Core Changes:
- Add CTA-861-G modes with VIC >= 193.
- Change error handling and remove bug_on in *drm_dev_init.
- Export drm_panel_of_backlight() correctly once more.
- Add support for lvds decoders.
- Convert drm/client and drm/(gem-,)fb-helper to drm-device based logging and update logging todo.

Driver Changes:
- Add support for dsi/px30 to rockchip.
- Add fb damage support to virtio.
- Use dma_resv locking wrappers in vc4, msm, etnaviv.
- Make functions in virtio static, and perform some simplifications.
- Add suspend support to sun4i.
- Add A64 mipi dsi support to sun4i.
- Add runtime pm suspend to komeda.
- Associated driver fixes.
