* mfd: ipaq-micro: Use __maybe_unused to hide pm functionsArnd Bergmann2016-03-161-1/+1
| | | | | | | | | | | | | | | 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.

* mfd: ipaq-micro: Convert to built-in platform driverLinus Walleij2015-08-111-23/+4
| | | | | | | | | | | 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.

* mfd: ipaq-micro: Convert prints to debug printsLinus Walleij2015-08-111-4/+4
| | | | | | | | There is a special function for debug prints rather than the usual hexdump function, let's use it. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>

* mfd: Add driver for Atmel Microcontroller on iPaq h3xxxLinus Walleij2014-06-031-0/+482
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.
