Javier Martinez Canillas 8be4efad81 mfd: max77686: Remove unused struct max77686_opmode_data
The defined struct max77686_opmode_data isn't used neither by
the max77686 mfd driver nor the drivers for its sub-devices.

Krzysztof Kozlowski 2b50635ea3 mfd: max77686/802: Remove support for board files
The driver is used only on Exynos based boards with DTS support.
After removal of board file support from max77686 and max77802 regulator
drivers, the MFD driver can be converted to DTS-only version. This
simplifies a little the code:
1. No dead (unused) entries in platform_data structure.
2. More code removed.
3. Regulator driver does not depend on allocated memory
   from MFD driver.
4. It makes also easier extending the regulator driver.

Add to the max77686 MFD driver dependency on CONFIG_OF because without
DTS the regulator drivers (max77686 and max77802) won't bind.

Javier Martinez Canillas 5356e0da49 regulator: max77802: Add header for operating modes
Add a header file for the max77802 constants that could be shared between
the regulator driver and Device Tree source files. Also, remove standby
and off opmodes since only normal and low power are valid operating modes.

Javier Martinez Canillas a259f3896a mfd: max77686: Add Maxim 77802 PMIC support
Maxim MAX77802 is a power management chip that contains 10 high
efficiency Buck regulators, 32 Low-dropout (LDO) regulators used
to power up application processors and peripherals, a 2-channel
32kHz clock outputs, a Real-Time-Clock (RTC) and a I2C interface
to program the individual regulators, clocks outputs and the RTC.

This patch adds support for MAX77802 to the MAX77686 driver and is
based on a driver added to the Chrome OS kernel 3.8 by Simon Glass.

Javier Martinez Canillas 6f1c1e71d9 mfd: max77686: Convert to use regmap_irq
By using the generic IRQ support in the Register map API, it
is possible to get rid max77686-irq.c and simplify the code.

Jonghwa Lee dae8a969d5 mfd: Add Maxim 77686 driver
This patch is device driver for MAX77686 chip.
MAX77686 is PMIC and includes regulator and rtc on it.
This driver is core of MAX77686 chip, so provides common support for
accessing on-chip devices. It uses irq_domain to manage irq and regmap
to read/write data to its register with i2c bus.
