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 V2:
* Implemented most of review findings (lots of small changes)
* Added comments where the review feedback was ignored
The following changes since commit b787f68c36d49bb1d9236f403813641efa74a031:
