2016-06-30mfd: max77620: Fix FPS switch statementsRhyland Klein
When configuring FPS during probe, assuming a DT node is present for FPS, the code can run into a problem with the switch statements in max77620_config_fps() and max77620_get_fps_period_reg_value(). Namely, in the case of chip->chip_id == MAX77620, it will set fps_[mix|max]_period but then fall through to the default switch case and return -EINVAL. Returning this from max77620_config_fps() will cause probe to fail.

2016-06-29mfd: max77620: Mask/unmask interrupt before/after servicing itLaxman Dewangan
The programming guidelines of the MAX77620 for servicing interrupt is: 1. When interrupt occurs from PMIC, mask the PMIC interrupt by setting GLBLM. 2. Read IRQTOP and service the interrupt. 3. Once all interrupts has been checked and serviced, the interrupt service routine un-masks the hardware interrupt line by clearing GLBLM. Add the pre and post interrupt service handler for mask and unmask the global interrupt mask bit (for step 1 and 3) as callback from regmap-irq.

2016-06-29mfd: max77620: Make it explicitly non-modularPaul Gortmaker
The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_MAX77620 drivers/mfd/Kconfig: bool "Maxim Semiconductor MAX77620 and MAX20024 PMIC Support" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_i2c_driver() uses the same init level priority as builtin_i2c_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.

2016-05-09mfd: max77620: Add core driver for MAX77620/MAX20024Laxman Dewangan
MAX77620/MAX20024 are Power Management IC from the MAXIM. It supports RTC, multiple GPIOs, multiple DCDC and LDOs, watchdog, clock etc. Add MFD drier to provides common support for accessing the device; additional drivers is developed on respected subsystem in order to use the functionality of the device.
