This adds a driver for the Atmel Microcontroller found on the
iPAQ h3xxx series. This device handles some keys, the
touchscreen, and the battery monitoring.
This is a port of a driver from handhelds.org 2.6.21 kernel,
written by Alessandro Gardich based on Andrew Christians
original HAL-driver. It has been heavily cleaned and
converted to mfd-core by Dmitry Artamonow and rewritten
again for the v3.x series kernels by Linus Walleij,
bringing back some of the functionality lost from Andrew's
original driver.

commit df73de9b0d412 ("mfd: syscon: Return -ENOSYS if CONFIG_MFD_SYSCON
is not enabled") introduced fallbacks for APIs, but missed out on adding
the header file. This would work only if linux/err.h is also included
in the source code from where this file is included. It would be better
to include linux/err.h in file to remove possible build errors.
Without this patch, we get following and similar build errors if this
header file is included in some source file and CONFIG_MFD_SYSCON is
not enabled.
include/linux/mfd/syscon.h: In function ‘syscon_node_to_regmap’:
include/linux/mfd/syscon.h:30:2: error: implicit declaration of function ‘ERR_PTR’ [-Werror=implicit-function-declaration]

The PRCM (Power/Reset/Clock Management) block exposes several subdevices
in different subsystems (clk, reset ...)
Add basic support for the PRCM unit with clk (AR100, AHB0, and APB0 clks)
and reset controller subdevices.
Other subdevices might be added later (if needed).

This patch introduces the preliminary support for PMICs X-Powers AXP202
and AXP209. The AXP209 and AXP202 are the PMUs (Power Management Unit)
used by A10, A13 and A20 SoCs and developed by X-Powers, a sister company
of Allwinner.
The core enables support for two subsystems:
- PEK (Power Enable Key)
- Regulators

If we pass syscon device node itself as first parameter to this function
there is no need to parse and find syscon device node. So by allowing
"property" parameter as NULL allow syscon_regmap_lookup_by_phandle to
consider passed argument "np" itself as a syscon device node "syscon_np".
This will help us in avoiding addition of "syscon" property in a device node
which points back to same device node in device tree.

During suspend the IRQ should be disabled even if this is not a wakeup
source. This is a proper way of fixing the IRQ handling issue during
resume (IRQ handler fails because I2C bus did not resume yet).
When device is suspended and max14577 interrupt is signaled the irq chip
will try to handle it regardless of wakeup source. Device could be woken
up by different IRQ but still the IRQ handler will try to read the
registers over I2C bus and fail because I2C bus won't be ready yet:
max14577 2-0025: Failed to read IRQ status: -5

The device type was stored in sec_pmic_dev state container twice:
- unsigned long type (initialized from of_device_id or i2c_device_id)
- int device_type (initialized as above or from board files when there
is no DTS)
The 'type' field was never used outside of probe so it can be safely
removed.
Change also the device_type in sec_pmic_dev and sec_platform_data to
unsigned long to avoid any casts.

In certain boards the source for the clk32k clock can be gated. In these
boards the clk32k clock can be provided to the driver and it is going to be
enabled/disabled when it is needed.
If the clk32k clock is not provided the driver will assume that it is always
running.

All boards using twl6040 configures the i2c bus to 400KHz. While twl6040's
defaults to normal mode (100KHz). So far twl6040 has no problem with i2c
communication in this configuration it is safer to select fast i2c mode.

If for some reason the boot loader enabled the audpwron GPIO we will have
pending IRQs to be handled. This seams to break twl6040 for some reason
leading to non working i2c communication (i2c timeouts). Clearing the INTID
register after we requested the audpwron GPIO (and set it to low) will
ensure that the chip will operate normally in this case as well.

The supply aliases for the MFD devices were being added using devres but
the device hasn't been added at this point and as such we can't use
devres.
The MFD already has a function that removes devices this patch uses the
non-devres versions of the supply alias functions and adds an unregister
in mfd_remove_devices_fn.

The rtc-s5m driver does not support all of S2M and S5M chipsets
supported by main MFD sec-core driver. For such chipsets unsupported by
rtc-s5m, the MFD sec-core driver initialized regmap with default config.
This config in such cases wouldn't work at all.
The main MFD sec-core driver shouldn't initialize regmap for child
drivers which is not used by them and even not valid.
Move the allocation of RTC I2C dummy device and initialization of RTC
regmap from main MFD sec-core driver to the rtc-s5m driver. The rtc-s5m
driver will use proper regmap config for supported devices.

After request_threaded_irq() is called there is a chance that an interrupt
may occur before the 'mc13xxx->lock' is initialized, which will trigger a kernel
oops.
In order to prevent that, move the initialization of 'mc13xxx->lock' prior to
requesting the interrupts.
