Pull radeon southern islands / trinity support from Dave Airlie: "This is support from AMD for their newest GPU and APUs. The products called RadeonHD 7xxx, and the Trinity APU series. This did come in a bit late, due to some over-complicated AMD internal review process, which from the outside seems unnecessary once the company has decided it wants to support open source. However as I said previously I'd rather not put the people who've got this hw for 3 months now being forced to use fglrx on it if there is open code. Its pretty well self contained and just plugs into the driver in various places." * 'drm-radeon-sitn-support' of git://people.freedesktop.org/~airlied/linux: (48 commits) drm/radeon/kms: update duallink checks for DCE6 drm/radeon/kms: add trinity pci ids drm/radeon/kms: add radeon_asic struct for trinity drm/radeon/kms: add support for ucode loading on trinity (v2) drm/radeon/kms/vm: set vram base offset properly for TN drm/radeon/kms: Update evergreen functions for trinity drm/radeon/kms: cayman gpu init updates for trinity drm/radeon/kms: Add checks for TN in the DP bridge code drm/radeon/kms/DCE6.1: ss is not supported on the internal pplls drm/radeon/kms: disable PPLL0 on DCE6.1 when not in use drm/radeon/kms: Adjust pll picker for DCE6.1 drm/radeon/kms: DCE6.1 disp eng pll updates drm/radeon/kms: DCE6.1 watermark updates for TN drm/radeon/kms: no support for internal thermal sensor on TN yet drm/radeon/kms: add trinity (TN) chip family drm/radeon/kms: Add SI pci ids drm/radeon: Update radeon_info_ioctl for SI.

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).
The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:
1. The DRM provides synchronized access to the graphics hardware via
the use of an optimized two-tiered lock.
2. The DRM enforces the DRI security policy for access to the graphics
hardware by only allowing authenticated X11 clients access to
restricted regions of memory.
3. The DRM provides a generic DMA engine, complete with multiple
queues and the ability to detect the need for an OpenGL context
switch.
4. The DRM is extensible via the use of small device-specific modules
that rely extensively on the API exported by the DRM module.
Documentation on the DRI is available from:
