Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "This is the main drm merge window pull request, changes all over the place, mostly normal levels of churn. Highlights: Core drm: More cleanups, fix race on connector/encoder naming, docs updates, object locking rework in prep for atomic modeset i915: mipi DSI support, valleyview power fixes, cursor size fixes, execlist refactoring, vblank improvements, userptr support, OOM handling improvements radeon: GPUVM tuning and large page size support, gart fixes, deep color HDMI support, HDMI audio cleanups nouveau: - displayport rework should fix lots of issues - initial gk20a support - gk110b support - gk208 fixes exynos: probe order fixes, HDMI changes, IPP consolidation msm: debugfs updates, misc fixes ast: ast2400 support, sync with UMS driver tegra: cleanups, hdmi + hw cursor for Tegra 124. panel: fixes existing panels add some new ones. ipuv3: moved from staging to drivers/gpu" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (761 commits) drm/nouveau/disp/dp: fix tmds passthrough on dp connector drm/nouveau/dp: probe dpcd to determine connectedness drm/nv50-: trigger update after all connectors disabled drm/nv50-: prepare for attaching a SOR to multiple heads drm/gf119-/disp: fix debug output on update failure drm/nouveau/disp/dp: make use of postcursor when its available drm/g94-/disp/dp: take max pullup value across all lanes drm/nouveau/bios/dp: parse lane postcursor data drm/nouveau/dp: fix support for dpms drm/nouveau: register a drm_dp_aux channel for each dp connector drm/g94-/disp: add method to power-off dp lanes drm/nouveau/disp/dp: maintain link in response to hpd signal drm/g94-/disp: bash and wait for something after changing lane power regs drm/nouveau/disp/dp: split link config/power into two steps drm/nv50/disp: train PIOR-attached DP from second supervisor drm/nouveau/disp/dp: make use of existing output data for link training drm/gf119/disp: start removing direct vbios parsing from supervisor drm/nv50/disp: start removing direct vbios parsing from supervisor drm/nouveau/disp/dp: maintain receiver caps in response to hpd signal drm/nouveau/disp/dp: create subclass for dp outputs ...

+ * Creates a new mm object that wraps some normal memory from the process
+ * context - user memory.
+ *
+ * We impose several restrictions upon the memory being mapped
+ * into the GPU.
+ * 1. It must be page aligned (both start/end addresses, i.e ptr and size).
+ * 2. It cannot overlap any other userptr object in the same address space.
+ * 3. It must be normal system memory, not a pointer into another map of IO
+ * space (e.g. it must not be a GTT mmapping of another object).
+ * 4. We only allow a bo as large as we could in theory map into the GTT,
+ * that is we limit the size to the total size of the GTT.
+ * 5. The bo is marked as being snoopable. The backing pages are left
+ * accessible directly by the CPU, but reads and writes by the GPU may
+ * incur the cost of a snoop (unless you have an LLC architecture).
+ *
+ * Synchronisation between multiple users and the GPU is left to userspace
+ * through the normal set-domain-ioctl. The kernel will enforce that the
+ * GPU relinquishes the VMA before it is returned back to the system
+ * i.e. upon free(), munmap() or process termination. However, the userspace
+ * malloc() library may not immediately relinquish the VMA after free() and
+ * instead reuse it whilst the GPU is still reading and writing to the VMA.
+ * Caveat emptor.
+ *
+ * Also note, that the object created here is not currently a "first class"
+ * object, in that several ioctls are banned. These are the CPU access
+ * ioctls: mmap(), pwrite and pread. In practice, you are expected to use
+ * direct access via your pointer rather than use those ioctls.
+ *
+ * If you think this is a good interface to use to pass GPU memory between
+ * drivers, please use dma-buf instead. In fact, wherever possible use
+ * dma-buf instead.

- * DPIO - a special bus for various display related registers to hide behind
+/**
+ * DOC: DPIO
+ *
+ * VLV and CHV have slightly peculiar display PHYs for driving DP/HDMI
+ * ports. DPIO is the name given to such a display PHY. These PHYs
+ * don't follow the standard programming model using direct MMIO
+ * registers, and instead their registers must be accessed trough IOSF
+ * sideband. VLV has one such PHY for driving ports B and C, and CHV
+ * adds another PHY for driving port D. Each PHY responds to specific
+ * IOSF-SB port.
+ *
+ * Each display PHY is made up of one or two channels. Each channel
+ * houses a common lane part which contains the PLL and other common
+ * logic. CH0 common lane also contains the IOSF-SB logic for the
+ * Common Register Interface (CRI) ie. the DPIO registers. CRI clock
+ * must be running when any DPIO registers are accessed.
+ *
+ * In addition to having their own registers, the PHYs are also
+ * controlled through some dedicated signals from the display
+ * controller. These include PLL reference clock enable, PLL enable,
+ * and CRI clock selection, for example.
*
- * DPIO is VLV only.
+ * Eeach channel also has two splines (also called data lanes), and
+ * each spline is made up of one Physical Access Coding Sub-Layer
+ * (PCS) block and two TX lanes. So each channel has two PCS blocks
+ * and four TX lanes. The TX lanes are used as DP lanes or TMDS
+ * data/clock pairs depending on the output type.
+ *
+ * Additionally the PHY also contains an AUX lane with AUX blocks
+ * for each channel. This is used for DP AUX communication, but
+ * this fact isn't really relevant for the driver since AUX is
+ * controlled from the display controller side. No DPIO registers
+ * need to be accessed during AUX communication,
+ *
+ * Generally the common lane corresponds to the pipe and
+ * the spline (PCS/TX) correponds to the port.
+ *
+ * For dual channel PHY (VLV/CHV):
+ *
+ * pipe A == CMN/PLL/REF CH0
+ *
+ * pipe B == CMN/PLL/REF CH1
+ *
+ * port B == PCS/TX CH0
+ *
+ * port C == PCS/TX CH1
+ *
+ * This is especially important when we cross the streams
+ * ie. drive port B with pipe B, or port C with pipe A.
+ *
+ * For single channel PHY (CHV):
+ *
+ * pipe C == CMN/PLL/REF CH0
+ *
+ * port D == PCS/TX CH0
+ *
+ * Note: digital port B is DDI0, digital port C is DDI1,
+ * digital port D is DDI2
