Merge tag 'drm-next-2019-05-09' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie: "This has two exciting community drivers for ARM Mali accelerators. Since ARM has never been open source friendly on the GPU side of the house, the community has had to create open source drivers for the Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx series. Well done to all involved and hopefully this will help ARM head in the right direction. There is also now the ability if you don't have any of the legacy drivers enabled (pre-KMS) to remove all the pre-KMS support code from the core drm, this saves 10% or so in codesize on my machine. i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo moves out of staging. There are also some rcar-du patches which crossover with media tree but all should be acked by Mauro.

+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.

+ * DOC: ras debugfs control interface
+ *
+ * It accepts struct ras_debug_if who has two members.
+ *
+ * First member: ras_debug_if::head or ras_debug_if::inject.
+ *
+ * head is used to indicate which IP block will be under control.
+ *
+ * head has four members, they are block, type, sub_block_index, name.
+ * block: which IP will be under control.
+ * type: what kind of error will be enabled/disabled/injected.
+ * sub_block_index: some IPs have subcomponets. say, GFX, sDMA.
+ * name: the name of IP.
+ *
+ * inject has two more members than head, they are address, value.
+ * As their names indicate, inject operation will write the
+ * value to the address.
+ *
+ * Second member: struct ras_debug_if::op.
+ * It has three kinds of operations.
+ * 0: disable RAS on the block. Take ::head as its data.
+ * 1: enable RAS on the block. Take ::head as its data.
+ * 2: inject errors on the block. Take ::inject as its data.
+ *
+ * How to use the interface?
+ * programs:
+ * copy the struct ras_debug_if in your codes and initialize it.
+ * write the struct to the control node.
+ *
+ * bash:
+ * echo op block [error [address value]] > .../ras/ras_ctrl
+ * op: disable, enable, inject
+ * disable: only block is needed
+ * enable: block and error are needed
+ * inject: error, address, value are needed
+ * block: umc, smda, gfx, .........
+ * see ras_block_string[] for details
+ * error: ue, ce
+ * ue: multi_uncorrectable
+ * ce: single_correctable
+ *
+ * here are some examples for bash commands,
+ * echo inject umc ue 0x0 0x0 > /sys/kernel/debug/dri/0/ras/ras_ctrl
+ * echo inject umc ce 0 0 > /sys/kernel/debug/dri/0/ras/ras_ctrl
+ * echo disable umc > /sys/kernel/debug/dri/0/ras/ras_ctrl
+ *
+ * How to check the result?
+ *
+ * For disable/enable, please check ras features at
+ * /sys/class/drm/card[0/1/2...]/device/ras/features
+ *
+ * For inject, please check corresponding err count at
+ * /sys/class/drm/card[0/1/2...]/device/ras/[gfx/sdma/...]_err_count
+ *
+ * NOTE: operation is only allowed on blocks which are supported.
+ * Please check ras mask at /sys/module/amdgpu/parameters/ras_mask
