dcdf11739d mfd: ipaq-micro: Use __maybe_unused to hide pm functions
The ipaq-micro driver uses SET_SYSTEM_SLEEP_PM_OPS() to
remove the reference to its resume function, but does
not use an #ifdef around the definition, so we get
a build warning:

drivers/mfd/ipaq-micro.c:379:12: error: 'micro_resume' defined but not used [-Werror=unused-function]

This adds a __maybe_unused annotation so the compiler knows
it can silently drop it instead of warning.

035faf4bd2 mfd: ipaq-micro: Convert to built-in platform driver
Signal that this is a built-in driver and call its probe function
immediately on init. Suppress binding attributes and delete the
.remove() function since it is never unloaded. Tag probe() and
functions only called from probe() with __init. Delete all module
macros since this is a pure built-in.

There is a special function for debug prints rather than the
usual hexdump function, let's use it.

dcc21cc09e mfd: Add driver for Atmel Microcontroller on iPaq h3xxx
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.
