mfd: Drop owner assignment from i2c_drivers

2015-08-11T14:08:48+00:00

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

mfd: max77686/802: Remove support for board files

2015-01-22T16:03:55+00:00

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.

mfd: max77686: Constify struct regmap_config

2015-01-22T15:56:14+00:00

The regmap_config struct may be const because it is not modified by the
driver and regmap_init() accepts pointer to const.

mfd: max77686: Remove check which is always true

2014-09-26T07:15:32+00:00

As 'reg' is unsigned, it can't be less than 0, so checking if it is
greater than or equal to 0 will always result in a true condition.

mfd: max77686: Add Maxim 77802 PMIC support

2014-07-25T14:31:48+00:00

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.

mfd: max77686: Remove unneeded OOM error message

2014-07-21T15:54:31+00:00

There is no need to print out-of-memory errors since this is already
done by the memory management subsystem which even calls dump_stack().

mfd: max77686: Make error checking consistent

2014-07-21T15:54:30+00:00

Error checking across the driver is mostly consistent besides
a few exceptions, so change these exceptions for consistency.

mfd: max77686: Return correct error when pdata isn't found

2014-07-21T15:54:29+00:00

When platform data is not found an -EIO (I/O error) code is returned.
This doesn't seem to be the correct error so better return -EINVAL
(Invalid argument) which is what most drivers do in this case.
