With device tree support for regulators, its needed that the
regulator_dev->dev device has the right of_node attached.
To be able to do this add an additional parameter to the
regulator_register() api, wherein the dt-adapted driver can
then pass this additional info onto the regulator core.Signed-off-by: Rajendra Nayak

Using C line continuation inside format strings is error prone.
Clean up the unintended whitespace introduced by misuse of \.
Neaten correctly used line continations as well for consistency.drivers/scsi/arcmsr/arcmsr_hba.c has these errors as well,
but arcmsr needs a lot more work and the driver should likely be
moved to staging instead.Signed-off-by: Joe Perches

The previous driver did not support BUCK1-DVS3, BUCK1-DVS4, and
BUCK2-DVS2 modes. This patch adds such modes and an option to block
setting buck1/2 voltages out of the preset values.Signed-off-by: MyungJoo Ham

The first releases of LP3974 have a large delay in RTC registers,
which requires 2 seconds of delay after writing to a rtc register
(recommended by National Semiconductor's engineers)
before reading it.If "rtc_delay" field of the platform data is true, the rtc driver
assumes that such delays are required. Although we have not seen
LP3974s without requiring such delays, we assume that such LP3974s
will be released soon (or they have done so already) and they are
supported by "lp3974" without setting "rtc_delay" at the platform
data.This patch adds delays with msleep when writing values to RTC registers
if the platform data has rtc_delay set.Signed-off-by: MyungJoo Ham

Change the interface used by set_voltage() to report the selected value
to the regulator core in terms of a selector used by list_voltage().
This allows the regulator core to know the voltage that was chosen
without having to do an explict get_voltage(), which would be much more
expensive as it will generally access hardware.Signed-off-by: Mark Brown

max8998_pmic_probe:
- modified to check if valid pins are defined at platform
data
- maximal voltage values (predefined at platform data) are uploaded to
max8998 devicemax8998_set_voltage_buck:
- BUCK1/2 voltages change between values already defined
- Checks if valid GPIO pins are passed from platform data
- If requested voltage cannot be satisfied from already defined values,
then one of free slots is used
- Predefined maximum voltages (as defined at platform data) are always

The MAX8998 chip have regulator and rtc features. The i2c slave address
of regulator and rtc is different, so needs each i2c client on i2c
operation functions.Also, this patch exports i2c operation functions instead of callback to
make easy to read.Signed-off-by: Joonyoung Shim

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.Changes since v1:

This patch adds voltage regulator driver for Maxim 8998 chip. This chip
is used on Samsung Aquila and GONI boards and provides following
functionalities:
- 4 BUCK voltage converters, 17 LDO power regulators and 5 other power
controllers
- battery chargerThis patch adds basic driver for voltage regulators and MAX 8998 MFD core.
