- dpm rework which fixes some issues and allows us to enable dpm by
default on CIK parts
- enable clockgating on CIK parts
- pci config reset. This is a bus-level chip reset that can be more
reliable than soft reset in certain cases. Disabled by default. Enable
with the hard_reset module option.
- big endian rptr/wrptr update fixes

drm/msm: add a330/apq8x74
Add support for adreno 330. Not too much different, just a few
differences in initial configuration plus setting OCMEM base.
Userspace support is already in upstream mesa.
Note that the existing DT code is simply using the bindings from
downstream android kernel, to simplify porting of this driver to
existing devices. These do not constitute any committed/stable
DT ABI. The addition of proper DT bindings will be a subsequent
patch, at which point (as best as possible) I will try to support
either upstream bindings or what is found in downstream android
kernel, so that existing device DT files can be used.

drm/msm: add mdp5/apq8x74
Add support for the new MDP5 display controller block. The mapping
between parts of the display controller and KMS is:
plane -> PIPE{RGBn,VIGn} \
crtc -> LM (layer mixer) |-> MDP "device"
encoder -> INTF /
connector -> HDMI/DSI/eDP/etc --> other device(s)
Unlike MDP4, it appears we can get by with a single encoder, rather
than needing a different implementation for DTV, DSI, etc. (Ie. the
register interface is same, just different bases.)
Also unlike MDP4, all the IRQs for other blocks (HDMI, DSI, etc) are
routed through MDP.
And finally, MDP5 has this "Shared Memory Pool" (called "SMP"), from
which blocks need to be allocated to the active pipes based on fetch
stride.

drm/msm: add hdmi support for apq8x74/mdp5
The HDMI block is basically the same between older SoC's with mdp4
display controller, and newer ones with mdp5.
So mostly this consists of better abstracting out the different sets of
regulators, clks, etc. In particular, for regulators and clks we can
split it up by what is needed for hot plug detect to work, and what is
needed to light up the display.
Also, 8x74 has a new phy.. a very simple one, but split out into a
different mmio space. And with mdp5, the irq is shared with mdp, so we
don't directly register our own irq handler.

drm/msm: add support for non-IOMMU systems
Add a VRAM carveout that is used for systems which do not have an IOMMU.
The VRAM carveout uses CMA. The arch code must setup a CMA pool for the
device (preferrably in highmem.. a 256m-512m VRAM pool in lowmem is not
cool). The user can configure the VRAM pool size using msm.vram module
param.
Technically, the abstraction of IOMMU behind msm_mmu is not strictly
needed, but it simplifies the GEM code a bit, and will be useful later
when I add support for a2xx devices with GPUMMU, so I decided to keep
this part.
It appears to be possible to configure the GPU to restrict access to
addresses within the VRAM pool, but this is not done yet. So for now
the GPU will refuse to load if there is no sort of mmu. Once address
based limits are supported and tested to confirm that we aren't giving
the GPU access to arbitrary memory, this restriction can be lifted

drm/tegra: Changes for v3.14-rc1
This series of changes brings DRM panel support as well as initial code
to register DSI hosts and peripherals and bind them to DSI drivers. The
panel and DSI code are both used by the simple panel driver.
The Tegra-specific changes build on top of this work to add support for
various panels found on Tegra boards. New drivers enable the DSI host
found on Tegra114 and a special hardware block that calibrates the pads
used for DSI and CSI. The host1x and the display controller drivers gain
basic Tegra124 support. To round of the new features, the DRM driver now
sports a very simple PRIME implementation.
In addition there are various improvements such as the host1x API being
exported so that client drivers (like the Tegra DRM driver) can be built
as modules. HDMI now does better power management and legacy FBDEV can
now be disabled via Kconfig (though it's still enabled by default). A
few sparse warnings have been squashed and various parts of the code
have become more robust.

drm/tegra: Add DSI support
This commit adds support for both DSI outputs found on Tegra. Only very
minimal functionality is implemented, so advanced features like ganged
mode won't work.
Due to the lack of other test hardware, some sections of the driver are
hardcoded to work with Dalmore.

drm/tegra: Disable outputs for power-saving
When an output is disabled, its DPMS mode is usually set to off. Instead
of only disabling the panel (if one is attached), turn the output off
entirely to save more power.
HDMI doesn't have any panels attached, so it previously didn't save any
power at all. With this commit, however, the complete HDMI interface
will be turned off, therefore allowing an attached monitor to go into a
standby mode.

drm/tegra: Track HDMI enable state
The DRM core doesn't track enable and disable state of encoders and/or
connectors, so calls to the output's .enable() and .disable() are not
guaranteed to be balanced. Track the enable state internally so that
calls to regulator and clock frameworks remain balanced.

gpu: host1x: clk_round_rate() can return a zero upon error
Treat both negative and zero return values from clk_round_rate() as
errors. This is needed since subsequent patches will convert
clk_round_rate()'s return value to be an unsigned type, rather than a
signed type, since some clock sources can generate rates higher than
(2^31)-1 Hz.
Eventually, when calling clk_round_rate(), only a return value of zero
will be considered a error. All other values will be considered valid
rates. The comparison against values less than 0 is kept to preserve
the correct behavior in the meantime.

gpu: host1x: Fix build warnings
When debugfs support isn't enabled, gcc complains about some variables
being unused. To avoid further #ifdefery, move debugfs specific setup
code into static functions and use IS_ENABLED(CONFIG_DEBUG_FS) to have
the compiler, rather than the preprocessor, discard them when unused.
The advantage of doing it this way is that all the code will be
compile-tested whether or not debugfs support is enabled.

drm: remove dev->vma_count
This is just used for a debugfs file, and we can easily reconstruct
this number by just walking the list twice. Which isn't really bad for
a debugfs file anyway.
So let's rip this out.
There's the other issue that the dev->vmalist itself is a bit useless,
since that can be reconstructed with all the memory mapping
information from proc. But remove that is a different topic entirely.
