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.

- * Try to read the BIOS display configuration and use it for the initial
- * fb configuration.
- *
- * The BIOS or boot loader will generally create an initial display
- * configuration for us that includes some set of active pipes and displays.
- * This routine tries to figure out which pipes and connectors are active
- * and stuffs them into the crtcs and modes array given to us by the
- * drm_fb_helper code.
- *
- * The overall sequence is:
- *   intel_fbdev_init - from driver load
- *     intel_fbdev_init_bios - initialize the intel_fbdev using BIOS data
- *     drm_fb_helper_init - build fb helper structs
- *     drm_fb_helper_single_add_all_connectors - more fb helper structs
- *   intel_fbdev_initial_config - apply the config
- *     drm_fb_helper_initial_config - call ->probe then register_framebuffer()
- *         drm_setup_crtcs - build crtc config for fbdev
- *           intel_fb_initial_config - find active connectors etc
- *         drm_fb_helper_single_fb_probe - set up fbdev
- *           intelfb_create - re-use or alloc fb, build out fbdev structs
- *
- * Note that we don't make special consideration whether we could actually
- * switch to the selected modes without a full modeset. E.g. when the display
- * is in VGA mode we need to recalculate watermarks and set a new high-res
- * framebuffer anyway.
