Merge tag 'drm-misc-next-2019-04-18' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v5.2:

UAPI Changes:
- Document which feature flags belong to which command in virtio_gpu.h
- Make the FB_DAMAGE_CLIPS available for atomic userspace only, it's useless for legacy.

Cross-subsystem Changes:
- Add device tree bindings for lg,acx467akm-7 panel and ST-Ericsson Multi Channel Display Engine MCDE
- Add parameters to the device tree bindings for tfp410
- iommu/io-pgtable: Add ARM Mali midgard MMU page table format
- dma-buf: Only do a 64-bits seqno compare when driver explicitly asks for it, else wraparound.
- Use the 64-bits compare for dma-fence-chains

Core Changes:
- Make the fb conversion functions use __iomem dst.
- Rename drm_client_add to drm_client_register
- Move intel_fb_initial_config to core.
- Add a drm_gem_objects_lookup helper
- Add drm_gem_fence_array helpers, and use it in lima.
- Add drm_format_helper.c to kerneldoc.

Driver Changes:
- Add panfrost driver for mali midgard/bitfrost.
- Converts bochs to use the simple display type.
- Small fixes to sun4i, tinydrm, ti-fp410.
- Fid aspeed's Kconfig options.
- Make some symbols/functions static in lima, sun4i and meson.
- Add a driver for the lg,acx467akm-7 panel.
