0f69c897f3 regulator: max8649 - fix setting extclk_freq
The SYNC bits are BIT6 and BIT7 of MAX8649_SYNC register.
pdata->extclk_freq could be [0|1|2].
(MAX8649_EXTCLK_26MHZ|MAX8649_EXTCLK_13MHZ|MAX8649_EXTCLK_19MHZ)
It requires to left shift 6 bits to properly set extclk_freq.

8ecee36adc regulator: wm8350-regulator - fix the logic of checking REGULATOR_MODE_STANDBY mode
In wm8350_dcdc_set_mode(), we set DCx_SLEEP bit of WM8350_DCDC_SLEEP_OPTIONS
register for REGULATOR_MODE_STANDBY mode.
( DCx_SLEEP bits: 0: Normal DC-DC operation 1: Select LDO mode )

In wm8350_dcdc_get_mode(), current logic to determinate
REGULATOR_MODE_STANDBY mode is just reverse.
( sleep is set should mean REGULATOR_MODE_STANDBY mode. )

e260999c66 regulator: wm831x-ldo - fix the logic to set REGULATOR_MODE_IDLE and REGULATOR_MODE_STANDBY modes
Problem description in current implementation:
When setting REGULATOR_MODE_IDLE mode, current implementation set
WM831X_LDO1_LP_MODE bit of ctrl_reg (which is wrong, it should clear the bit).
But due to a missing break statement for case REGULATOR_MODE_IDLE, the code
fall through to case REGULATOR_MODE_STANDBY and then clear
WM831X_LDO1_LP_MODE bit. So it still looks OK when checking the status
by wm831x_gp_ldo_get_mode().

When setting REGULATOR_MODE_STANDBY mode, it just does not work.
wm831x_gp_ldo_get_mode() will still return REGULATOR_MODE_IDLE because
the accordingly WM831X_LDO1_LP_MODE bit is clear.

Correct behavior should be:
Clear WM831X_LDO1_LP_MODE bit of ctrl_reg for REGULATOR_MODE_IDLE mode.
Set WM831X_LDO1_LP_MODE bit of ctrl_reg for REGULATOR_MODE_STANDBY mode.

d06563cb86 regulator: 88pm8607 - fix value range checking for accessing info->vol_table
In choose_voltage(), we use i as array index of info->vol_table.
The valid value range for i should be 0 .. ARRAY_SIZE(info->vol_table) - 1.

Take LDO1 as example, ARRAY_SIZE(LDO1_table) is 4, vol_nbits of LDO1 is 2.
for (i = 0; i < (2 << info->vol_nbits); i++)  is equivalent to
for (i = 0; i < 8; i++)
which is wrong.

The same value range checking also applies for index in pm8607_list_voltage().

c5a4655db9 regulator: MAX8998: set_voltage bugfix. ramp_up delay and min/max voltage
Two issues are addressed for max8998_set_voltage function.

1. Min/Max Voltage.

	max8998_set_voltage had been using the voltage value of

	min ( voltage[i] >= max_vol , i )

	This is corrected to use:

	min ( voltage[i] >= min_vol , i )

2. Ramp Up Delay.

	max8998_set_voltage should provide delay for BUCK1/2
if ENRAMP is on. It reads RAMP value from ONOFF4 register to determine
RAMP delay length. However, when max8998_set_voltage's new voltage is
lower than the previous, we don't care because it does not deteriorate
the stability.

- rebased onto latest regulator-for-next tree

7d14831e21 regulator: tps6507x: allow driver to use DEFDCDC{2,3}_HIGH register
Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

In TPS6507x, depending on the status of DEFDCDC{2,3} pin either
DEFDCDC{2,3}_LOW or DEFDCDC{2,3}_HIGH register needs to be read or
programmed to change the output voltage.

The current driver assumes DEFDCDC{2,3} pins are always tied low
and thus operates only on DEFDCDC{2,3}_LOW register. This need
not always be the case (as is found on OMAP-L138 EVM).

Unfortunately, software cannot read the status of DEFDCDC{2,3} pins.
So, this information is passed through platform data depending on
how the board is wired.

979da89a9c ab3100: fix off-by-one value range checking for voltage selector
We use voltage selector as an array index for typ_voltages.
Thus the valid range for voltage selector should be 0..voltages_len-1.

fbae3fb154 i2c: Remove all i2c_set_clientdata(client, NULL) in drivers
I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04d to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

fa661258a2 mfd: AB3100 register access change to abx500 API
The interface for the AB3100 is changed to make way for the
ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson
Analog Baseband chips. The register access functions are moved
out to a separate struct abx500_ops. In this way the interface
is moved from the implementation and the sub functionality drivers
can keep their interface intact when chip infrastructure and
communication mechanisms changes. We also define the AB3550
device IDs and the AB3550 platform data struct and convert
the catenated 32bit event to an array of 3 x 8bits.

812f9e9d42 mfd: Renamed ab3100.h to abx500.h
The goal here is to make way for a more general interface for the
analog baseband chips ab3100 ab3550 ab550 and future chips.

This patch have been divided into two parts since both changing name
and content of a file is not recommended in git.
