[PATCH v3 0/2] mfd: max77693: improve regmap support

[PATCH v3 0/2] mfd: max77693: improve regmap support

[Robert Baldyga]

This patchset modifies max77693 driver and associated function drivers
to improve regmap support. It removes unnecessary wrapper functions,
which make code more clean, and modifies IRQ handling to use regmap irq.

Best regards
Robert Baldyga
Samsung R&D Institute Poland

Changelog:

v3:
- fix some style problems

v2: https://lkml.org/lkml/2014/4/29/32
- change type of array given to regmap_bulk_read() from unsigned int to u8
- remove mfd_remove_devices() call from error handling, since it's not needed
- call disable_irq()/enable_irq() in suspend/resume regardless of wakeup source

v1: https://lkml.org/lkml/2014/4/28/298

[PATCH v3 1/2] mfd: max77693: remove unnecessary wrapper functions

[Robert Baldyga]

This patch removes wrapper functions used to access regmap, and
make driver using regmap_*() functions instead.

[PATCH v3 2/2] mfd: max77693: handle IRQs using regmap

[Robert Baldyga]

This patch modifies mfd driver to use regmap for handling interrupts.
It allows to simplify irq handling process. This modifications needed
to make small changes in function drivers, which use interrupts.
