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.

+ST-Ericsson Multi Channel Display Engine MCDE
+
+The ST-Ericsson MCDE is a display controller with support for compositing
+and displaying several channels memory resident graphics data on DSI or
+LCD displays or bridges. It is used in the ST-Ericsson U8500 platform.
+
+Required properties:
+
+- compatible: must be:
+  "ste,mcde"
+- reg: register base for the main MCDE control registers, should be
+  0x1000 in size
+- interrupts: the interrupt line for the MCDE
+- epod-supply: a phandle to the EPOD regulator
+- vana-supply: a phandle to the analog voltage regulator
+- clocks: an array of the MCDE clocks in this strict order:
+  MCDECLK (main MCDE clock), LCDCLK (LCD clock), PLLDSI
+  (HDMI clock), DSI0ESCLK (DSI0 energy save clock),
+  DSI1ESCLK (DSI1 energy save clock), DSI2ESCLK (DSI2 energy
+  save clock)
+- clock-names: must be the following array:
+  "mcde", "lcd", "hdmi"
+  to match the required clock inputs above.
+- #address-cells: should be <1> (for the DSI hosts that will be children)
+- #size-cells: should be <1> (for the DSI hosts that will be children)
+- ranges: this should always be stated
+
+Required subnodes:
+
+The devicetree must specify subnodes for the DSI host adapters.
+These must have the following characteristics:
+
+- compatible: must be:
+  "ste,mcde-dsi"
+- reg: must specify the register range for the DSI host
+- vana-supply: phandle to the VANA voltage regulator
+- clocks: phandles to the high speed and low power (energy save) clocks
+  the high speed clock is not present on the third (dsi2) block, so it
+  should only have the "lp" clock
+- clock-names: "hs" for the high speed clock and "lp" for the low power
+  (energy save) clock
+- #address-cells: should be <1>
+- #size-cells: should be <0>
+
+Display panels and bridges will appear as children on the DSI hosts, and
+the displays are connected to the DSI hosts using the common binding
+for video transmitter interfaces; see
+Documentation/devicetree/bindings/media/video-interfaces.txt
+
+If a DSI host is unused (not connected) it will have no children defined.
