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.

v3 (swarren):
* Moved of_irq_init() call into board-dt.c to avoid ifdef'ing it.
- Even with a dummy replacement if !CONFIG_OF, the reference from
tegra_dt_irq_match[] to gic_of_init() would still have to be ifdef'd
- It's plausible that tegra_dt_irq_match[] may need to contain more

for board-dt.c than irq.c

wm8903_platform_data.gpio_cfg[] was intended to be interpreted as follows:
0: Don't touch this GPIO's configuration register
1..7fff: Write that value to the GPIO's configuration register
8000: Write zero to the GPIO's configuration register
other: Undefined (invalid)
The rationale is that platform data is usually global data, and a value of
zero means that the field wasn't explicitly set to anything (e.g. because
the field was new to the pdata type, and existing users weren't update to
initialize it) and hence the value zero should be ignored. 0x8000 is an
explicit way to get 0 in the register.
The code worked this way until commit 7cfe561 "ASoC: wm8903: Expose GPIOs
through gpiolib", where the behaviour was changed due to my lack of
awareness of the above rationale.
This patch reverts to the intended behaviour, and updates all in-tree users
to use the correct scheme. This also makes WM8903 consistent with other
devices that use a similar scheme.
WM8903_GPIO_NO_CONFIG is also renamed to WM8903_GPIO_CONFIG_ZERO so that
its name accurately reflects its purpose.

*_pinmux_init() register the GPIO and pinmux devices so that they're ready
before any other device needs them.
*_pinmux_init() are also called by board-dt.c in order to set up the GPIO
and pinmux configurations. In this case, if we register the devices, they
end up being probed once due to this registration, and a second time due
to a device-tree node (or vice-versa). The second probe fails since the
memory regions are already requested. Besides, we don't actually want the
duplicated devices.
To avoid this duplicate registration, modify *_pinmux_init() to check
whether it's running on a DT machine. If not, register the pinmux devices.
If so, don't register them.
Finally, modify board-dt.c to call the *_pinmux_init() after all devices have
been instantiated from device-tree. This allows the GPIO and pinmux devices
to be instantiated and initialized before calling functions to configure the
hardware.
This has one disadvantage: The pinmux and GPIO initialization now happens
after /all/ devices are instantiated, rather than after just gpio and
pinmux but before anything else. So the correct HW configuration is not
in place when e.g. the SD/MMC device is probed. Long-term, this should be
solved by doing both:
a) Initializing the HW state from DT nodes during GPIO and pinmux device
probe.
b) Using the deferred driver probe mechanism, so that drivers can defer
their probe until after the gpio and pinmux drivers have probed.
v2: s/int is_dt/bool is_dt/
v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing
an explicit parameter into the function from outside.

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.

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.

By not definining a custom gpio_to_irq, the default gpiolib version is
used, allowing platform consolidation.
irq_to_gpio is deprecated and in the process of being removed. Make that
happen now for ARM Tegra.
This also partially fixes the Tegra build; it was broken because gpio.h
referred to EINVAL, which wasn't always defined when <mach/gpio.h> was
included.

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
and only have to do something extra if you need to. This should
encourage the use of the trivial default implementation.
As an additional bonus, several gpio.h header files become empty.

Many of the gpio_to_irq implementations use the gpiolib version of this
function. Provide the standard gpiolib gpio_to_irq() for everyone, but
allow platforms to override it if they wish. Add the neccessary
overrides for those platforms which do not use the standard definition.

a tegra20 device tree. So far it only registers the on-chip devices,
but it will be refined in follow on patches to configure clocks and
pin IO from the device tree also.
