The offset of the first spare bit register on Tegra210 is 0x380, but
account for the fixed offset of 0x100 in the fuse accessor.

There's a mixture of core_* and soc_* prefixes for variables storing
information related to the VDD_CORE rail. Choose one (soc_*) and use it
more consistently.

Unifying the drivers makes it easier to restrict the legacy probing
paths to 32-bit ARM. This in turn will come in handy as support for
new 64-bit ARM SoCs is added.

For backwards-compatibility with old device trees, if no APBMISC node
exists this driver hard-codes the I/O memory region. All 64-bit ARM
device tree files are recent enough that they can be required to have
this node, and therefore the legacy code path is not required.
Based on work done by Paul Walmsley <pwalmsley@nvidia.com>.

Pull ARM SoC driver updates from Kevin Hilman:
"Some of these are for drivers/soc, where we're now putting
SoC-specific drivers these days. Some are for other driver subsystems
where we have received acks from the appropriate maintainers.
Some highlights:
- simple-mfd: document DT bindings and misc updates
- migrate mach-berlin to simple-mfd for clock, pinctrl and reset
- memory: support for Tegra132 SoC
- memory: introduce tegra EMC driver for scaling memory frequency
- misc. updates for ARM CCI and CCN busses"

Tegra132 is very similar to Tegra124 from a peripheral point of view and

Pull drm updates from Dave Airlie:
"Highlights:
- AMD KFD driver merge
This is the AMD HSA interface for exposing a lowlevel interface for
GPGPU use. They have an open source userspace built on top of this
interface, and the code looks as good as it was going to get out of
tree.
- Initial atomic modesetting work
The need for an atomic modesetting interface to allow userspace to
try and send a complete set of modesetting state to the driver has
arisen, and been suffering from neglect this past year. No more,
the start of the common code and changes for msm driver to use it
are in this tree. Ongoing work to get the userspace ioctl finished
and the code clean will probably wait until next kernel.
- DisplayID 1.3 and tiled monitor exposed to userspace.
Tiled monitor property is now exposed for userspace to make use of.
- Rockchip drm driver merged.
- imx gpu driver moved out of staging
Other stuff:
- core:
panel - MIPI DSI + new panels.
expose suggested x/y properties for virtual GPUs
- i915:

Some Tegra drivers might be compiled as kernel modules, and they need the
fuse information for initialization. One example is the GK20A Nouveau
driver. It needs the GPU speedo value to calculate frequency-voltage
table. So export the tegra_sku_info.

Rather than rely on explicit initialization order called from SoC setup
code, use a plain initcall and rely on initcall ordering to take care of
dependencies.
This driver exposes some functionality (querying the chip ID) needed at
very early stages of the boot process. An early initcall is good enough
provided that some of the dependencies are deferred to later stages. To
make sure any abuses are easily caught, output a warning message if the
chip ID is queried while it can't be read yet.

The Tegra fuse header's dummy functions for the case where Tegra20 is
disabled are inconsistent with the correct prototypes, and have some
syntax errors. Fix these. While at it, fix the indentation level of
the dummy function bodies.

The Tegra20 fuse driver is the only user of tegra_apb_readl_using_dma().
Therefore we can simply the code by incorporating the APB DMA handling into
the driver directly. tegra_apb_writel_using_dma() is dropped because there
are no users.

Implement fuse driver for Tegra20, Tegra30, Tegra114 and Tegra124. This
replaces functionality previously provided in arch/arm/mach-tegra, which
is removed in this patch.
While at it, move the only user of the global tegra_revision variable
over to tegra_sku_info.revision and export tegra_fuse_readl() to allow
drivers to read calibration fuses.
