Currently, MICVDD only binds because it is both the regulator name and
the consumer name and we will always match against the regulator name
regardless of the consumer device. If the regulator was renamed using
the init_data ASoC will no longer be able to locate the supply, as it
will be looking on the CODEC device where as the MICVDD consumer is on
the Arizona device. Add a mapping as we do for the other regulators.

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 df73de9b ("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.

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

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:

 - 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

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.
