Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux 

Pull drm updates from Dave Airlie:
 "This is the main drm pull request for v4.2.

  I've one other new driver from freescale on my radar, it's been posted
  and reviewed, I'd just like to get someone to give it a last look, so
  maybe I'll send it or maybe I'll leave it.

  There is no major nouveau changes in here, Ben was working on
  something big, and we agreed it was a bit late, there wasn't anything
  else he considered urgent to merge.

  There might be another msm pull for some bits that are waiting on
  arm-soc, I'll see how we time it.

  This touches some "of" stuff, acks are in place except for the fixes
  to the build in various configs,t hat I just applied.

  Summary:

  New drivers:
      - virtio-gpu:
                KMS only pieces of driver for virtio-gpu in qemu.
                This is just the first part of this driver, enough to run
                unaccelerated userspace on. As qemu merges more we'll start
                adding the 3D features for the virgl 3d work.
      - amdgpu:
                a new driver from AMD to driver their newer GPUs. (VI+)
                It contains a new cleaner userspace API, and is a clean
                break from radeon moving forward, that AMD are going to
                concentrate on. It also contains a set of register headers
                auto generated from AMD internal database.

  core:
      - atomic modesetting API completed, enabled by default now.
      - Add support for mode_id blob to atomic ioctl to complete interface.
      - bunch of Displayport MST fixes
      - lots of misc fixes.

  panel:
      - new simple panels
      - fix some long-standing build issues with bridge drivers

  radeon:
      - VCE1 support
      - add a GPU reset counter for userspace
      - lots of fixes.

  amdkfd:
      - H/W debugger support module
      - static user-mode queues
      - support killing all the waves when a process terminates
      - use standard DECLARE_BITMAP

  i915:
      - Add Broxton support
      - S3, rotation support for Skylake
      - RPS booting tuning
      - CPT modeset sequence fixes
      - ns2501 dither support
      - enable cmd parser on haswell
      - cdclk handling fixes
      - gen8 dynamic pte allocation
      - lots of atomic conversion work

  exynos:
      - Add atomic modesetting support
      - Add iommu support
      - Consolidate drm driver initialization
      - and MIC, DECON and MIPI-DSI support for exynos5433

  omapdrm:
      - atomic modesetting support (fixes lots of things in rewrite)

  tegra:
      - DP aux transaction fixes
      - iommu support fix

  msm:
      - adreno a306 support
      - various dsi bits
      - various 64-bit fixes
      - NV12MT support

  rcar-du:
      - atomic and misc fixes

  sti:
      - fix HDMI timing complaince

  tilcdc:
      - use drm component API to access tda998x driver
      - fix module unloading

  qxl:
      - stability fixes"

* 'drm-next' of git://people.freedesktop.org/~airlied/linux: (872 commits)

Device-Tree bindings for Samsung Exynos SoC mobile image compressor (MIC)
MIC (mobile image compressor) resides between decon and mipi dsi. Mipi dsi is
not capable to transfer high resoltuion frame data as decon can send. MIC
solves this problem by compressing the frame data by 1/2 before it is
transferred through mipi dsi. The compressed frame data must be uncompressed in
the panel PCB.
Required properties:
- compatible: value should be "samsung,exynos5433-mic".
- reg: physical base address and length of the MIC registers set and system
register of mic.
- clocks: must include clock specifiers corresponding to entries in the
clock-names property.
- clock-names: list of clock names sorted in the same order as the clocks
property. Must contain "pclk_mic0", "sclk_rgb_vclk_to_mic0".
- samsung,disp-syscon: the reference node for syscon for DISP block.
- ports: contains a port which is connected to decon node and dsi node.
address-cells and size-cells must 1 and 0, respectively.
- port: contains an endpoint node which is connected to the endpoint in the
decon node or dsi node. The reg value must be 0 and 1 respectively.
Example:
SoC specific DT entry:

Device-Tree bindings for Samsung Exynos SoC display controller (DECON)
DECON (Display and Enhancement Controller) is the Display Controller for the
Exynos series of SoCs which transfers the image data from a video memory
buffer to an external LCD interface.
Required properties:
- compatible: value should be "samsung,exynos5433-decon";
- reg: physical base address and length of the DECON registers set.
- interrupts: should contain a list of all DECON IP block interrupts in the
order: VSYNC, LCD_SYSTEM. The interrupt specifier format
depends on the interrupt controller used.
- interrupt-names: should contain the interrupt names: "vsync", "lcd_sys"
in the same order as they were listed in the interrupts
property.
- clocks: must include clock specifiers corresponding to entries in the
clock-names property.
- clock-names: list of clock names sorted in the same order as the clocks
property. Must contain "aclk_decon", "aclk_smmu_decon0x",
"aclk_xiu_decon0x", "pclk_smmu_decon0x", clk_decon_vclk",
"sclk_decon_eclk"
- ports: contains a port which is connected to mic node. address-cells and
size-cells must 1 and 0, respectively.
- port: contains an endpoint node which is connected to the endpoint in the mic
node. The reg value muset be 0.
- i80-if-timings: specify whether the panel which is connected to decon uses
i80 lcd interface or mipi video interface. This node contains
no timing information as that of fimd does. Because there is
no register in decon to specify i80 interface timing value,
it is not needed, but make it remain to use same kind of node
in fimd and exynos7 decon.

/* AMD hw uses four ACPI control methods:
* 1. ATIF
* ARG0: (ACPI_INTEGER) function code
* ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
* OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
* ATIF provides an entry point for the gfx driver to interact with the sbios.
* The AMD ACPI notification mechanism uses Notify (VGA, 0x81) or a custom
* notification. Which notification is used as indicated by the ATIF Control
* Method GET_SYSTEM_PARAMETERS. When the driver receives Notify (VGA, 0x81) or
* a custom notification it invokes ATIF Control Method GET_SYSTEM_BIOS_REQUESTS
* to identify pending System BIOS requests and associated parameters. For
* example, if one of the pending requests is DISPLAY_SWITCH_REQUEST, the driver
* will perform display device detection and invoke ATIF Control Method
* SELECT_ACTIVE_DISPLAYS.
*
* 2. ATPX
* ARG0: (ACPI_INTEGER) function code
* ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
* OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
* ATPX methods are used on PowerXpress systems to handle mux switching and
* discrete GPU power control.
*
* 3. ATRM
* ARG0: (ACPI_INTEGER) offset of vbios rom data
* ARG1: (ACPI_BUFFER) size of the buffer to fill (up to 4K).
* OUTPUT: (ACPI_BUFFER) output buffer
* ATRM provides an interfacess to access the discrete GPU vbios image on
* PowerXpress systems with multiple GPUs.
*
* 4. ATCS
* ARG0: (ACPI_INTEGER) function code
* ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
* OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
* ATCS provides an interface to AMD chipset specific functionality.

* GART
* The GART (Graphics Aperture Remapping Table) is an aperture
* in the GPU's address space. System pages can be mapped into
* the aperture and look like contiguous pages from the GPU's
* perspective. A page table maps the pages in the aperture
* to the actual backing pages in system memory.
*
* Radeon GPUs support both an internal GART, as described above,
* and AGP. AGP works similarly, but the GART table is configured
* and maintained by the northbridge rather than the driver.
* Radeon hw has a separate AGP aperture that is programmed to
* point to the AGP aperture provided by the northbridge and the
* requests are passed through to the northbridge aperture.
* Both AGP and internal GART can be used at the same time, however
* that is not currently supported by the driver.
*
* This file handles the common internal GART management.
