Constify a number of static struct resource. The only usage of the
structs are to assign their address to the resources field in the
mfd_cell struct. This allows the compiler to put them in read-only
memory. Done with the help of Coccinelle.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

The kerneldocs for both tps65217_reg_write() and tps65217_update_bits()
describe their first arguments as 'tps65217', when in reality these are
simply called 'tps'.
Fixes the following W=1 warnings:
drivers/mfd/tps65217.c:215: warning: Function parameter or member 'tps' not described in 'tps65217_reg_write'
drivers/mfd/tps65217.c:215: warning: Excess function parameter 'tps65217' description in 'tps65217_reg_write'

Currently the driver boots only via device tree hence add a
dependency on CONFIG_OF. This leaves with a bunch of unused code
so clean that up. This patch also makes use of probe_new function
in place of the probe function so as to avoid passing i2c_device_id.

TPS65217 INT pin is used for the system wakeup from suspend mode.
This patch enables push button or charger input event as a wakeup source.

Rework the IRQ handler by using HW IRQ number and status bit.
Each HW IRQ number is matched with TPS65217 register layout[*].
(USB IRQ number is 0, AC is 1, Push button is 2)
When an interrupt is enabled, mask bit should be cleared (unmasked).
If an interrupt is disabled, then mask bit should be set (masked).
This mask value is updated into the TPS65217 register in irq_sync_unlock().
Mask bit and interrupt status bit can be handled with HW IRQ number.
Eventually, additional IRQ data, 'tps65217_irqs[]' and the function,
'irq_to_tps65217_irq()' are not necessary.

TPS65217 interrupt register includes read/writeable mask bits with
read-only status bits. (bit 4, 5, 6 are R/W, bit 0, 1, 2 are RO)
And reserved bit is not required.
Register update operation is preferred for disabling all interrupts during
the device initialisation.

TPS65217 MFD is an interrupt controller and MFD slave devices like
tps65217-charger and tps65217-pwrbutton request an interrupt to handle
each HW event.
Currently, TPS65217 IRQ name is not defined, so the result is as below.
root@arm:~# cat /proc/interrupts
...
182: 0 INTC 7 Level tps65217-irq
183: 0 - 1 Edge tps65217-charger
185: 0 - 2 Edge tps65217_pwrbutton
This patch specifies the name of the interrupt controller.
182: 0 INTC 7 Level tps65217-irq

TPS65217 IRQ domain should be removed and initialised as NULL when the
module is unloaded for the next use. When tps65217.ko is loaded again,
it causes the page fault. This patch fixes the error below.

The tps65217 gained a new warning when building with W=1:
drivers/mfd/tps65217.c:85:1: error: 'inline' is not at beginning of declaration [-Werror=old-style-declaration]
This fixes it by putting the 'inline' modifier before 'const'.

Add support for handling IRQs: power button, AC and USB power state
changes. Mask and interrupt bits are shared within one register, which
prevents us to use regmap_irq implementation. New irq_domain is created in
order to add interrupt handling for each tps65217's subsystem. IRQ
resources have been added for charger subsystem to be able to notify about
AC and USB state changes.

The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So technically there's no need for a driver to export
the OF table since currently it's not used.
In fact, the I2C device ID table is mandatory for I2C drivers since
a i2c_device_id is passed to the driver's probe function even if the
I2C core used the OF table to match the driver.
And since the I2C core uses different tables, OF-only drivers needs to
have duplicated data that has to be kept in sync and also the dev node
compatible manufacturer prefix is stripped when reporting the MODALIAS.
To avoid the above, the I2C core behavior may be changed in the future
to not require an I2C device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table to prevent
breaking module autoloading if that happens.

Pull MFS update from Samuel Ortiz:
"This is the MFD patch set for the 3.8 merge window.
We have several new drivers, most of the time coming with their sub
devices drivers:
- Austria Microsystem's AS3711
- Nano River's viperboard
- TI's TPS80031, AM335x TS/ADC,
- Realtek's MMC/memstick card reader
- Nokia's retu
We also got some notable cleanups and improvements:
- tps6586x got converted to IRQ domains.
- tps65910 and tps65090 moved to the regmap IRQ API.
- STMPE is now Device Tree aware.
- A general twl6040 and twl-core cleanup, with moves to the regmap
I/O and IRQ APIs and a conversion to the recently added PWM
framework.
- sta2x11 gained regmap support.
Then the rest is mostly tiny cleanups and fixes, among which we have
Mark's wm5xxx and wm8xxx patchset."
Far amount of annoying but largely trivial conflicts. Many due to
__devinit/exit removal, others due to one or two of the new drivers also
having come in through another tree.

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties. This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern. There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.
Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts. The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

Regulator platform data handling was mistakenly added to MFD
driver. So we will see build errors if we compile MFD drivers
without CONFIG_REGULATOR. This patch moves regulator platform
data handling from TPS65217 MFD driver to regulator driver.
This makes MFD driver independent of REGULATOR framework so
build error is fixed if CONFIG_REGULATOR is not set.
drivers/built-in.o: In function `tps65217_probe':
tps65217.c:(.devinit.text+0x13e37): undefined reference
to `of_regulator_match'
This patch also fix allocation size of tps65217 platform data.
Current implementation allocates a struct tps65217_board for each
regulator specified in the device tree. But the structure itself
provides array of regulators so one instance of it is sufficient.
