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.
