[PATCH v4 00/18] new MFD LoCoMo driver set

[Dmitry Eremin-Solenikov <dbaryshkov@xxxxxxxxx>]

Sharp Zaurus SL-5500 and SL-5600 use special companion Gate Array.
With this patchset I tried to modernise and restructure the LoCoMo drivers.

* Use platform bus and mfd core code
* Use GPIO API instead of custom locomo GPIO code
* Use irqdomains to manage IRQs
* Split mixed locomolcd driver to lcd and backlight parts
* Implement IRQ handling in GPIO driver
* Implement SPI driver used as a host for mmc_spi device to control SD cards

Changes since v3:
* Removed magic values in locomo irq handling code
* Using mutex in locomokbd driver
* Dropped empty locomokbd_remove
* Small rearrangement of headers/comments/etc in core and input drivers

The following changes since commit b787f68c36d49bb1d9236f403813641efa74a031:
