here is the pull request for the etnaviv DRM driver. It includes the DT bindings
and the driver itself, platform devicetree changes will be merged through the
respective SoC trees. Otherwise it's just a squashed version of the V2 patches
that have been on the list for a while.
* 'drm-etnaviv-next' of git://git.pengutronix.de/git/lst/linux:
MAINTAINERS: add maintainer and reviewers for the etnaviv DRM driver
drm/etnaviv: add initial etnaviv DRM driver
drm/etnaviv: add devicetree bindings
devicetree: add vendor prefix for Vivante Corporation
This adds the etnaviv DRM driver and hooks it up in Makefiles
and Kconfig.

This pull request brings in 3D acceleration support for the VC4 GPU.
While there is still performance work to be done (particularly
surrounding RCL generation), the CL submit ABI should be settled and
done now.
* tag 'drm-vc4-next-2015-12-11' of http://github.com/anholt/linux:
drm/vc4: Add an interface for capturing the GPU state after a hang.
drm/vc4: Add support for async pageflips.
drm/vc4: Add support for drawing 3D frames.
drm/vc4: Bind and initialize the V3D engine.
drm/vc4: Fix a typo in a V3D debug register.
drm/vc4: Add an API for creating GPU shaders in GEM BOs.
drm/vc4: Add create and map BO ioctls.
drm/vc4: Add a BO cache.
drm: Create a driver hook for allocating GEM object structs.
Here are the patchset to add get_eld op to audio component for
communicating more directly between i915 and HD-audio.
Currently, the HDMI/DP audio status and ELD are notified and obtained
via the hardware-level communication over HD-audio unsolicited event
and verbs although the graphics driver holds the exactly same
information. As we already have a notification via audio component,
this is another step forward; namely, the audio driver may fetch
directly the audio status and ELD via the new component op.
The commits are based on Dave's latest drm-next branch.

Userspace can pass in an offset that it presumes the object is located
at. The kernel will then do its utmost to fit the object into that
location. The assumption is that userspace is handling its own object
locations (for example along with full-ppgtt) and that the kernel will
rarely have to make space for the user's requests.

v2: Fixed incorrect eviction found by Michal Winiarski - fix suggested by Chris
Wilson. Fixed incorrect error paths causing crash found by Michal Winiarski.
(Not published externally)
v3: Rebased because of trivial conflict in object_bind_to_vm. Fixed eviction
to allow eviction of soft-pinned objects when another soft-pinned object used
by a subsequent execbuffer overlaps reported by Michal Winiarski.
(Not published externally)
v4: Moved soft-pinned objects to the front of ordered_vmas so that they are
pinned first after an address conflict happens to avoid repeated conflicts in
rare cases (Suggested by Chris Wilson). Expanded comment on
drm_i915_gem_exec_object2.offset to cover this new API.
v5: Added I915_PARAM_HAS_EXEC_SOFTPIN parameter for detecting this capability
(Kristian). Added check for multiple pinnings on eviction (Akash). Made sure
buffers are not considered misplaced without the user specifying
EXEC_OBJECT_SUPPORTS_48B_ADDRESS. User must assume responsibility for any
addressing workarounds. Updated object2.offset field comment again to clarify
NO_RELOC case (Chris). checkpatch cleanup.
v6: Trivial rebase on latest drm-intel-nightly
v7: Catch attempts to pin above the max virtual address size and return
EINVAL (Tvrtko). Decouple EXEC_OBJECT_SUPPORTS_48B_ADDRESS and
EXEC_OBJECT_PINNED flags, user must pass both flags in any attempt to pin
something at an offset above 4GB (Chris, Daniel Vetter).

v2: Use __u32-style types.
Signed-off-by: Eric Anholt <eric@anholt.net>
The user submission is basically a pointer to a command list and a
pointer to uniforms. We copy those in to the kernel, validate and
relocate them, and store the result in a GPU BO which we queue for
execution.
v2: Drop support for NV shader recs (not necessary for GL), simplify
vc4_use_bo(), improve bin flush/semaphore checks, use __u32 style
types.
Signed-off-by: Eric Anholt <eric@anholt.net>
Since we have no MMU, the kernel needs to validate that the submitted
shader code won't make any accesses to memory that the user doesn't
control, which involves banning some operations (general purpose DMA
writes), and tracking where we need to write out pointers for other
operations (texture sampling). Once it's validated, we return a GEM
BO containing the shader, which doesn't allow mapping for write or
exporting to other subsystems.
v2: Use __u32-style types.
Signed-off-by: Eric Anholt <eric@anholt.net>
While there exist dumb APIs for creating and mapping BOs, one of the
rules is that drivers doing 3D acceleration have to provide their own
APIs for buffer allocation (besides, the pitch/height parameters of
the dumb alloc don't really make sense for a lot of 3D allocations).
v2: Use __u32-style types, use "drm.h" instead of <drm/drm.h>.

Store the upper dword of the register offset in the whitelist as well.
This would allow it to read register where the two halves aren't sitting
right next to each other, and it'll make it easier to make register
access type safe.
While at it change the register offsets to u32 from u64. Our register
space isn't quite that big, yet :)

As we've enabled multiplatform kernels on ARM, and greatly done away with
the contents under arch/arm/mach-*, there's still need for SoC-related
drivers to go somewhere.
Many of them go in through other driver trees, but we still have
drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
that might be shared between ARM and ARM64 (or just in general makes
sense to not have under the architecture directory).
This branch contains mostly such code:
- Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate
with power management blocks on these SoCs for use by clock, regulator and
bus frequency drivers.
- Allwinner Reduced Serial Bus driver, again used to communicate with PMICs.
- Drivers for ARM's SCPI (System Control Processor). Not to be confused with
PSCI (Power State Coordination Interface). SCPI is used to communicate with
the assistant embedded cores doing power management, and we have yet to see
how many of them will implement this for their hardware vs abstracting in
other ways (or not at all like in the past).
- To make confusion between SCPI and PSCI more likely, this release also
includes an update of PSCI to interface version 1.0.
- Rockchip support for power domains.
- A driver to talk to the firmware on Raspberry Pi.

Pull i2c updates from Wolfram Sang:
- New drivers: UniPhier (with and without FIFO)
- some drivers got some bigger rework: ismt, designware, img-scb (rcar
had to be reverted because issues were showing up just lately)
- ACPI: reworked the device scanning and added support for muxes
... and quite a lot of driver bugfixes and cleanups this time. All
files touched outside of the i2c realm have proper acks.
