7a31f6f48b ARM: IOMMU: Tegra30: Add iommu_ops for SMMU driver
Tegra 30 IOMMU H/W, SMMU (System Memory Management Unit). This patch
implements struct iommu_ops for SMMU for the upper IOMMU API.

This H/W module supports multiple virtual address spaces(domain x4),
and manages 2 level H/W translation pagetable.

Remove the now empty arch_reset() from all the mach/system.h includes,

no longer does anything useful.

For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions.  As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.

Add support for tegra30 SoC. This includes a device tree compatible type for

The clock framework is still missing, which prevents most drivers from working.
The basic IRQs are the same, so remove the dependency on
CONFIG_ARCH_TEGRA_2x_SOC.

742face03f arm/tegra: prepare clock code for multiple tegra variants
Rework the tegra20 clock code to support multiple tegra variants :

 * remove tegra2_periph_reset_assert/tegra2_periph_reset_deassert. This
   functionality should be in clock.c.

 * remove tegra_sdmmc_tap_delay and export tegra2_sdmmc_tap_delay
   directly. This feature is handled inside the sdmmc block from tegra30
   onwards. So there is no need for support in the clock code beyond
   tegra20. There are no in tree users of this function.

48f2eceefb arm/tegra: pinmux: ioremap registers
Use ioremap to obtain access to registers instead of using static
mappings. This reduces the number of users of the static mappings, which
will eventually allow them to be removed.

Note that on Tegra30, the number of register "banks" will decrease to 2,
and the packing of specific bits into registers will change significantly.
That's why this change adds the "*_bank" fields to the pingroup tables,
rather than implementing some more hard-coded scheme.

Also, completely remove the implementation of suspend/resume; Tegra doesn't
yet support suspend/resume, and the implementation is complex for the
general pinmux driver:

* Not all registers are used within each bank, so we probably shouldn't
  just iterate over every register in the bank, and save/restore it,
  since that would mean touching undefined registers.

* Registers are shared between pingroups, so we can't simply iterate over
  each pingroup, and save/restore the registers it uses.

It'd probably be best have probe() calculate a bitmask of actually-used
registers for each bank, and have suspend/resume iterate over those
bitmaps.

Oh, and Real Soon Now, I should be looking into converting this driver to
the new pinmux/pinctrl subsystem, so I didn't want to put too much work
into the current incarnation.

v2: s/space/bank/ to match comments on reg_* fields in pinmux.h.
    Re-order bank/reg parameters to pg_readl/pg_writel.

e748b7310f ARM: tegra: annotate IO_*_VIRT pointers
Provide __iomem annotation for IO_*_VIRT pointers, which will propagate
up through IO_TO_VIRT(). Also fixes a 0 to NULL conversion of the base
case to silence sparse.

Unfortunately map_desc takes an unsigned long for the pointer instead of
a void __iomem *. For now, cast explicitly for those cases.

639da5ee37 ARM: add an extra temp register to the low level debugging addruart macro
Some platforms (like OMAP not to name it) are doing rather complicated
hacks just to determine the base UART address to use.  Let's give their
addruart macro some slack by providing an extra work register which will
allow for much needed cleanups.

This is basically a no-op as this commit is only adding the extra argument
to the macro but no one is using it yet.

Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead.  This means that by default, you get the trivial implementation

encourage the use of the trivial default implementation.

As an additional bonus, several gpio.h header files become empty.

632095ea15 ARM: tegra: add tegra_gpio_table and tegra_gpio_config
To give one place to setup the pins that are used as GPIOs instead
of as their pinmuxed functions. Specifying enabled as false explicitly
disables the gpio mode of that pin (if left on by firmware).

This should remove the need for calling these from specific drivers and
thus reduce tegra-specific code from them.

9743b38969 ARM: tegra: clock: Add function to set SDMMC tap delay
The SDMMC controllers have extra bits in the clock source
register that adjust the delay between the clock and data
to compenstate for delays on the PCB.  The values need to
be set from the clock code so the clock can be locked
during the read-modify-write on the clock source register.
