Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "Highlights: - drm: Generic display port aux features, primary plane support, drm master management fixes, logging cleanups, enforced locking checks (instead of docs), documentation improvements, minor number handling cleanup, pseudofs for shared inodes. - ttm: add ability to allocate from both ends - i915: broadwell features, power domain and runtime pm, per-process address space infrastructure (not enabled) - msm: power management, hdmi audio support - nouveau: ongoing GPU fault recovery, initial maxwell support, random fixes - exynos: refactored driver to clean up a lot of abstraction, DP support moved into drm, LVDS bridge support added, parallel panel support - gma500: SGX MMU support, SGX irq handling, asle irq work fixes - radeon: video engine bringup, ring handling fixes, use dp aux helpers - vmwgfx: add rendernode support" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (849 commits) DRM: armada: fix corruption while loading cursors drm/dp_helper: don't return EPROTO for defers (v2) drm/bridge: export ptn3460_init function drm/exynos: remove MODULE_DEVICE_TABLE definitions ARM: dts: exynos4412-trats2: enable exynos/fimd node ARM: dts: exynos4210-trats: enable exynos/fimd node ARM: dts: exynos4412-trats2: add panel node ARM: dts: exynos4210-trats: add panel node ARM: dts: exynos4: add MIPI DSI Master node drm/panel: add S6E8AA0 driver ARM: dts: exynos4210-universal_c210: add proper panel node drm/panel: add ld9040 driver panel/ld9040: add DT bindings panel/s6e8aa0: add DT bindings drm/exynos: add DSIM driver exynos/dsim: add DT bindings drm/exynos: disallow fbdev initialization if no device is connected drm/mipi_dsi: create dsi devices only for nodes with reg property drm/mipi_dsi: add flags to DSI messages Skip intel_crt_init for Dell XPS 8700 ...

+Exynos MIPI DSI Master
+
+Required properties:
+ - compatible: "samsung,exynos4210-mipi-dsi"
+ - reg: physical base address and length of the registers set for the device
+ - interrupts: should contain DSI interrupt
+ - clocks: list of clock specifiers, must contain an entry for each required
+ entry in clock-names
+ - clock-names: should include "bus_clk"and "pll_clk" entries
+ - phys: list of phy specifiers, must contain an entry for each required
+ entry in phy-names
+ - phy-names: should include "dsim" entry
+ - vddcore-supply: MIPI DSIM Core voltage supply (e.g. 1.1V)
+ - vddio-supply: MIPI DSIM I/O and PLL voltage supply (e.g. 1.8V)
+ - samsung,pll-clock-frequency: specifies frequency of the "pll_clk" clock
+ - #address-cells, #size-cells: should be set respectively to <1> and <0>
+ according to DSI host bindings (see MIPI DSI bindings [1])
+
+Optional properties:
+ - samsung,power-domain: a phandle to DSIM power domain node
+
+Child nodes:
+ Should contain DSI peripheral nodes (see MIPI DSI bindings [1]).
+
+Video interfaces:
+ Device node can contain video interface port nodes according to [2].
+ The following are properties specific to those nodes:
+
+ port node:
+ - reg: (required) can be 0 for input RGB/I80 port or 1 for DSI port;
+
+ endpoint node of DSI port (reg = 1):
+ - samsung,burst-clock-frequency: specifies DSI frequency in high-speed burst
+ mode
+ - samsung,esc-clock-frequency: specifies DSI frequency in escape mode
