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.
