The WM831x IRQ set_type() operation is doing a direct register write when
called but since set_type() is called with the bus lock held this isn't
legal and could cause deadlocks in the IRQ core.
Fix this by posting the updates into an array and syncing in the
bus_sync_unlock() callback.

This patch enables IRQ handling for MAX8997/8966 chips.
Please note that Fuel-Gauge-related IRQs are not implemented in this
initial release. The fuel gauge module in MAX8997 is identical to
MAX17042, which is already in Linux kernel. In order to use the
already-existing MAX17042 driver for fuel gauge module in MAX8997, the
main interrupt handler of MAX8997 should relay related interrupts to
MAX17042 driver. However, in order to do this, we need to modify
MAX17042 driver as well because MAX17042 driver does not have any
interrupt handlers for now. We are not going to implement this in this
initial release as it is not crucial in basic operations of MAX8997.

Replace mfd_shared_platform_driver_register with mfd_clone_cell. The
former was called by an mfd client, and registered both a platform driver
and device. The latter is called by an mfd driver, and registers only a
platform device.
The downside of this is that mfd drivers need to be modified whenever
new clients are added that share a cell; the upside is that it fits
Linux's driver model better. It's also simpler.
This also converts cs5535-mfd/olpc-xo1 from the old API. cs5535-mfd
now creates the olpc-xo1-{acpi,pms} devices, while olpc-xo1 binds to
them via platform drivers.

This patch supports PMIC/Regulator part of MAX8997/MAX8966 MFD.
In this initial release, selecting voltages or current-limit
and switching on/off the regulators are supported.
Controlling voltages for DVS with GPIOs is not implemented fully
and requires more considerations: it controls multiple bucks (selection
of 1, 2, and 5) at the same time with SET1~3 gpios. Thus, when DVS-GPIO
is activated, we lose the ability to control the voltage of a single
buck regulator independently; i.e., contolling a buck affects other two
bucks. Therefore, using the conventional regulator framework directly
might be problematic. However, in this driver, we try to choose
a setting without such side effect of affecting other regulators and
then try to choose a setting with the minimum side effect (the sum of
voltage changes in other regulators).
On the other hand, controlling all the three bucks simultenously based
on the voltage set table may help build cpufreq and similar system
more robust; i.e., all the three voltages are consistent every time
without glitches during transition.

This revamps the interface so that AB8500 GPADCs are fetched by
name. Probed GPADCs are added to a list and this list is searched
for a matching GPADC. This makes it possible to have multiple
AB8500 GPADC instances instead of it being a singleton, and
rids the need to keep a GPADC pointer around in the core AB8500
MFD struct.
Currently the match is made to the device name which is by default
numbered from the device instance such as "ab8500-gpadc.0" but
by using the .init_name field of the device a more intiutive
naming for the GPADC blocks can be achieved if desired.

This adds functions to enable platform_device sharing for mfd clients.
Each platform driver (mfd client) that wants to share an mfd_cell's
platform_device uses the mfd_shared_platform_driver_{un,}register()
functions instead of platform_driver_{un,}register(). Along with
registering the platform driver, these also register a new platform
device with the same characteristics as the original cell, but a different
name. Given an mfd_cell with the name "foo", drivers that want to
share access to its resources can call mfd_shared_platform_driver_register
with platform drivers named (for example) "bar" and "baz". This
will register two platform devices and drivers named "bar" and "baz"
that share the same cell as the platform device "foo". The drivers
can then call "foo" cell's enable hooks (or mfd_shared_cell_enable)
to enable resources, and obtain platform resources as they normally
would.
This deals with platform handling only; mfd driver-specific details,
hardware handling, refcounting, etc are all dealt with separately.

desired.

Previously, one would set the mfd_cell's platform_data/data_size to point
to the current mfd_cell in order to pass that information along to drivers.
This causes the current mfd_cell to always be available to drivers. It
also adds a wrapper function for fetching the mfd cell from a platform
device, similar to what originally existed for mfd devices.
Drivers who previously used platform_data for other purposes can still
use it; the difference is that mfd_get_data() must be used to
access it (and the pdata structure is no longer allocated in
mfd_add_devices).
Note that mfd_get_data is intentionally vague (in name) about where
the data is stored; variable name changes can come later without having
to touch brazillions of drivers.

which requires 2 seconds of delay after writing to a rtc register
(recommended by National Semiconductor's engineers)
before reading it.
If "rtc_delay" field of the platform data is true, the rtc driver
assumes that such delays are required. Although we have not seen
LP3974s without requiring such delays, we assume that such LP3974s
will be released soon (or they have done so already) and they are
supported by "lp3974" without setting "rtc_delay" at the platform
data.

The define for number of regulators is moved from ab8500-core to
ab8500-regulator so that the regulator driver can be updated
independently of ab8500-core. This also changes the platform
configuration structure of ab8500-core so that it contains a
pointer to the regulator_init_data array plus number of
regulators instead of an fixed size array of pointers to
regulator_init_data.

For example, with SDIO WLAN cards, some transfers happen with buffers at
odd addresses, whereas the SH-Mobile DMA engine requires even addresses
for SDHI. This patch extends the tmio driver with a bounce buffer, that
is used for single entry scatter-gather lists both for sending and
receiving. If we ever encounter unaligned transfers with multi-element
sg lists, this patch will have to be extended. For now it just falls
back to PIO in this and other unsupported cases.

those pins to be reassigned as simple GPIOs (which may be triggered even

The charger interrupts on the WM831x are unconditionally a wake source
for the system. If the power driver is not able to monitor them (for
example, due to the IRQ line not having been wired up on the system)
then any charger interrupt will prevent the system suspending for any
meaningful amount of time since nothing will ack them.
Avoid this issue by manually acknowledging these interrupts when we
suspend the WM831x core device if they are masked. If software is
actually using the interrupts then they will be unmasked and this
change will have no effect.
