[Kevin Strasser <kevin.strasser-VuQAYsv1563Yd54FQh9/CA@public.gmane.org>]

mfd changes since v1:
- Use a mutex instead of spinlock
- Poll for hardware mutex without timeout
- Restructure mfd cell structs, only call mfd_add_devices once
- Drop pointless BUG_ONs
- EXPORT_SYMBOL -> EXPORT_SYMBOL_GPL
- kempld_*_mutex_set_index -> kempld_*_mutex
- Removed kempld_try_get_mutex
- Drop last_index
- Remove EFT code
- Drop unused includes
- Use devm_ioport_map
- Restructure to get rid of forward function prototypes
- Renamed module parameter force_ident -> force_device_id
- Dropped force_unlock module parameter
- Formatting fixes

i2c changes since v1:
- Always disable bus during suspend,
- Detect was_active in probe
- Remove i2c-kempld.h
- Clean up register definitions
- Use the correct device for printing
- Set default bus frequency to 100kHz
- Drop irq support
- Drop now1 driver
- Remove i2c-mux code
- Clean up includes
- Use devm_kzalloc
- Formatting fixes

gpio changes since v1:
- Change label from kempld-gpio -> gpio-kempld
- Drop unnecessary include seq_file.h
- Register and value parameters to kempld_get_bit and kempld_bitop are now u8
- Status variable in kempld_bitop is now u8
- Fix kempld_gpio_pincount(). hweight16 doesn't work, but __ffs does
- Drop interrupt support
- Drop gpio-kempld.h
- Use helper functions for bit and read operations
- Use generic DEBUG_FS code
- Use devm_kzalloc
- Get gpio_base from platform data
- Drop all module parameters
- Use module_platform_driver
- Drop unused includes
- Include device.h instead of slab.h for devm_kzalloc
- Some cleanup here and there

watchdog changes since v1:
- Use watchdog framework
- Allocate stages statically
- Drop now1 driver
- Use devm_kzalloc
- Change default timeout to 30 seconds
- Drop unused includes
- General formatting cleanup
