Merge tag 'drm-for-v4.14' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "This is the main drm pull request for 4.14 merge window. I'm sending this early, as my continuing journey into fatherhood is occurring really soon now, I'm going to be mostly useless for the next couple of weeks, though I may be able to read email, I doubt I'll be doing much patch applications or git sending. If anything urgent pops up I've asked Daniel/Jani/Alex/Sean to try and direct stuff towards you. Outside drm changes: Some rcar-du updates that touch the V4L tree, all acks should be in place. It adds one export to the radix tree code for new i915 use case. There are some minor AGP cleanups (don't see that too often). Changes to the vbox driver in staging to avoid breaking compilation.

+Synopsys DesignWare MIPI DSI host controller
+============================================
+
+This document defines device tree properties for the Synopsys DesignWare MIPI
+DSI host controller. It doesn't constitue a device tree binding specification
+by itself but is meant to be referenced by platform-specific device tree
+bindings.
+
+When referenced from platform device tree bindings the properties defined in
+this document are defined as follows. The platform device tree bindings are
+responsible for defining whether each optional property is used or not.
+
+- reg: Memory mapped base address and length of the DesignWare MIPI DSI
+ host controller registers. (mandatory)
+
+- clocks: References to all the clocks specified in the clock-names property
+ as specified in [1]. (mandatory)
+
+- clock-names:
+ - "pclk" is the peripheral clock for either AHB and APB. (mandatory)
+ - "px_clk" is the pixel clock for the DPI/RGB input. (optional)
+
+- resets: References to all the resets specified in the reset-names property
+ as specified in [2]. (optional)
+
+- reset-names: string reset name, must be "apb" if used. (optional)
+
+- panel or bridge node: see [3]. (mandatory)
