ARM: tegra: remove board files
This branch removes all remaining board files for Tegra; booting is
now through device tree only.
Related, the Harmony DT is augmented with regulators, since this allows
removal of board-harmony-power.c; no other boards had regulator support.
This change depends on an enhancement to the TPS6586x regulator driver,
hence the dependency mentioned below.

Pull in a dependent branch from Mark Brown's regulator tree for the tegra/cleanup branch.

From Stephen Warren:

always selecting USE_OF since we're converting to device-tree-only this
merge window, and removing includes of some header files as part of

Harmony uses a TPS6586x regulator. Instantiate this, and hook up a
couple of fixed GPIO-controlled regulators too.
Based on Ventana regulator patch by Stephen Warren <swarren@nvidia.com>
and converted to Harmony.
swarren made the following changes:
* Added ldo0 regulator configuration to device tree, and updated
board-harmony-pcie.c for the new regulator name.
* Fixed vdd_1v05's voltage from 10.5V to 1.05V.
* Modified board-harmony-pcie.c to obtain the en_vdd_1v05 GPIO number at
run-time from device tree instead of hard-coding it.
* Removed board-harmony{-power.c,.h} now that they're unused.
* Disabled vdd_1v05 regulator; the code in board-harmony-pcie.c hijacks
this GPIO for now. This will be fixed when the PCIe driver is re-
written as a driver. The code can't regulator_get("vdd_1v05") right
now, because the vdd_1v05 regulator's probe gets deferred due to its
supply being the PMIC, which gets probed after the regulator the first
time around, and this dependency is only resolved by repeated probing,
which happens when deferred_probe_initcall() is called, which happens
in a late initcall, whose runtime order relative to harmony_pcie_init()
is undefined, since that's also called from a late initcall.
* Removed unused harmony_pcie_initcall().

Harmony can be booted using device tree with equal functionality as when
booted using a board file. Remove as much of the board file as is
possible, since it's no longer needed.
Two special-cases are still left in board-dt-tegra20.c, since the Tegra
PCIe driver doesn't support device tree yet, and the Harmony .dts file
doesn't yet describe regulators which are needed for PCIe. This logic is
now enabled unconditionally rather than via CONFIG_MACH_HARMONY. While
this is more code than other boards, it's still unlikely to be much of a
problem, and both regulators and PCIe should be supported via device tree
in the near future, allowing the remaining code to be removed.

Perform the same operation here: push the registers down

ARM: ks8695: use [readl|writel]_relaxed()
ARM: ks8695: merge the timer header into the timer driver
Old platforms using ancient gettimeoffset() and other arcane
APIs are standing in the way of cleaning up the ARM kernel.
The gettimeoffset() was also broken: it would try to read out
the timer counter value, while this would not work (the
counter statically returns the initially programmed value)
so the implementation would anyway fall back to a homebrew
version of jiffie calculation.
This is an attempt at blind-coding a generic time and clocksource
driver for the platform by way of a datasheet and looking at the
old code.

As Stephen Rothwell reports, a849088aa1 ("ARM: Fix ioremap() of
address zero") from the arm-current tree and commit c279443709 ("ARM:
Add fixed PCI i/o mapping") from the arm-soc tree conflict in
a nontrivial way in arch/arm/mm/mmu.c.
Rob Herring explains:
The PCI i/o reserved area has a dummy physical address of 0 and
needs to be skipped by ioremap searches. So we don't set
VM_ARM_STATIC_MAPPING to prevent matches by ioremap. The vm_struct
settings don't really matter when we do the real mapping of the
i/o space.
Since commit a849088aa1 is at the start of the fixes branch
in the arm tree, we can merge it into the branch that contains
the other ioremap changes.

Andreas Bombe reported that the added ktime_t overflow checking added to
timespec_valid in commit 4e8b14526c ("time: Improve sanity checking of
timekeeping inputs") was causing problems with X.org because it caused
timeouts larger then KTIME_T to be invalid.
Previously, these large timeouts would be clamped to KTIME_MAX and would
never expire, which is valid.
This patch splits the ktime_t overflow checking into a new
timespec_valid_strict function, and converts the timekeeping codes
internal checking to use this more strict function.
