drm/msm/mdp4: Clean up some MDP4 clocks
Fix some issues with MDP4 clocks:
- mdp4_dtv_encoder tries to get "src_clk", which is a RCG(TV_SRC) in
MSM8960 and APQ8064. This isn't something the driver should access or
configure. Instead of this, configure the "mdp_clk" (MDP_TV_CLK), a
branch clock in MMCC that has the TV_SRC as its parent. Setting
rate/enabling the "mdp_clk" will eventually configure "src_clk", which
is what we want.
- Rename "mdp_clk" to "tv_clk" because that's slightly less confusing.
- Rename "mdp_axi_clk" to "bus_clk" because that's what we do elsewhere
too.

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.

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

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.

Merge branch 'linux-4.8' of git://github.com/skeggsb/linux into drm-next
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.
