drm/drm-kms.rst: Remove unused drm_fourcc.h include directive

Right now there's nothing, and kernel-doc produces a warning because
of that. Remove it until we need it for a clean build.

drm: Unexport drm_connector_unregister_all()

This has now been removed from all drivers as it is performed centrally
as a part of device unregistration for modesetting drivers. With the last
user gone, we can unexport it from the DRM module. That requires us to
move the code slightly to avoid the need for a forward declaration.

drm/vgem: Attach sw fences to exported vGEM dma-buf (ioctl)

vGEM buffers are useful for passing data between software clients and
hardware renders. By allowing the user to create and attach fences to
the exported vGEM buffers (on the dma-buf), the user can implement a
deferred renderer and queue hardware operations like flipping and then
signal the buffer readiness (i.e. this allows the user to schedule
operations out-of-order, but have them complete in-order).

This also makes it much easier to write tightly controlled testcases for
dma-buf fencing and signaling between hardware drivers.

v2: Don't pretend the fences exist in an ordered timeline, but allocate
a separate fence-context for each fence so that the fences are
unordered.
v3: Make the debug output more interesting, and show the signaled status.
v4: Automatically signal the fence to prevent userspace from
indefinitely hanging drivers.

drm/tegra: Changes for v4.8-rc1

This set of changes contains a bunch of cleanups to the host1x driver as
well as the addition of a pin controller for DPAUX, which is required by
boards to configure the DPAUX pads in AUX mode (for DisplayPort) or I2C
mode (for HDMI and DDC).

Included is also a bit of rework of the SOR driver in preparation to add
DisplayPort support as well as some refactoring and cleanup.

Finally, all output drivers are converted to runtime PM, which greatly
simplifies the handling of clocks and resets.

drm/vc4: Fix definition of QPU_R_MS_REV_FLAGS

We don't use it in shader validation currently, so it had no effect,

drm/vc4: Add a getparam to signal support for branches.

Userspace needs to know if it can create shaders that do branching.
Otherwise, for backwards compatibility with old kernels it needs to
lower if statements to conditional assignments.

Signed-off-by: Eric Anholt <eric@anholt.net>

drm/vc4: Add support for branching in shader validation.

We're already checking that branch instructions are between the start
of the shader and the proper PROG_END sequence.  The other thing we
need to make branching safe is to verify that the shader doesn't read
past the end of the uniforms stream.

To do that, we require that at any basic block reading uniforms have
the following instructions:

load_imm temp, <next offset within uniform stream>
add unif_addr, temp, unif

The instructions are generated by userspace, and the kernel verifies
that the load_imm is of the expected offset, and that the add adds it
to a uniform.  We track which uniform in the stream that is, and at
draw call time fix up the uniform stream to have the address of the
start of the shader's uniforms at that location.

drm/vc4: Add a bitmap of branch targets during shader validation.

This isn't used yet, it's just a first step toward loop validation.
During the main parsing of instructions, we need to know when we hit a
new basic block so that we can reset validated state.

v2: Fix a stray semicolon after an if block.  (caught by kbuild test).

drm/tegra: sor: Reject HDMI 2.0 modes

drm/tegra: sor: Prepare for generic PM domain support

The SOR driver for Tegra requires the SOR power partition to be enabled.
Now that Tegra supports the generic PM domain framework we manage the
SOR power partition via this framework. However, the sequence for
gating/ungating the SOR power partition requires that the SOR reset is
asserted/de-asserted at the time the SOR power partition is
gated/ungated, respectively. Now that the reset control core assumes
that resets are exclusive, the Tegra generic PM domain code and the SOR
driver cannot request the same reset unless we mark the reset as shared.
Sharing resets will not work in this case because we cannot guarantee
that the reset will be asserted/de-asserted at the appropriate time.
Therefore, given that the Tegra generic PM domain code will handle the
resets, do not request the reset in the SOR driver if the SOR device has
a PM domain associated.

drm/tegra: sor: Use sor1_src clock to set parent for HDMI

dt-bindings: display: tegra: Add source clock for SOR

The SOR clock can have various sources, with the most commonly used
being the sor_safe, pll_d2_out0, pll_dp and sor_brick clocks. These
are configured using a three level mux, of which the first 2 levels
can be treated as one. The direct parents of the SOR clock are the
sor_safe, sor_brick and sor_src clocks, whereas the pll_d2_out0 and
pll_dp clocks can be selected as parents of the sor_src clock via a
second mux.

Previous generations of Tegra have only supported eDP and LVDS with
the SOR, where LVDS was never used on publicly available hardware.
Clocking for this only ever required the first level mux (to select
between sor_safe and sor_brick).

Tegra210 has a new revision of the SOR that supports HDMI and hence
needs to support the second level mux to allow selecting pll_d2_out0
as the SOR clock's parent. This second mux is knows as sor_src, and
operating system software needs a reference to it in order to select
the proper parent.

drm: Don't overwrite user ioctl arg unless requested

Currently, we completely ignore the user when it comes to the in/out
direction of the ioctl argument, as we simply cannot trust userspace.
(For example, they might request a copy of the modified ioctl argument
when the driver is not expecting such and so leak kernel stack.)
However, blindly copying over the target address may also lead to a
spurious EFAULT, and a failure after the ioctl was completed
successfully. This is important in order to avoid an ABI break when
extending an ioctl from IOR to IORW. Similar to how we only copy the
intersection of the kernel arg size and the user arg size, we only want
to copy back the kernel arg data iff both the kernel and userspace
request the copy.

Here's an initial drm-next pull for nouveau 4.8, highlights:
- GK20A/GM20B volt and clock improvements.
- Initial support for GP100/GP104 GPUs, GP104 will not yet support
acceleration due to NVIDIA having not released firmware for them as of yet.

drm/nouveau/bus: remove cpu_coherent flag

This flag's only remaining function is to ignore the uncached flag for
BOs on coherent architectures.

However the reason for allocating an object uncache on a non-coherent
architecture (namely because the cost of doing explicit flushes/
invalidations is higher than the benefit of caching the data because
accesses are few and far between) should also apply on architectures for
which coherency is maintained implicitly. Thus allocate coherent objects
as uncached on all architectures.

drm/nouveau/ttm: remove special handling of coherent objects

TTM-allocated coherent objects were populated using the DMA API and
accessed using the mapping it returned to workaround coherency
issues. These issues seem to have been solved, thus remove this extra
case to handle and use the regular kernel mapping functions.
