[NEW DRIVER V2 0/7] DA9058 PMIC - please comment on this new driver

This is submission attempt number 2 to have this driver included in
the linux kernel source tree. This is the driver for the Dialog DA9058.

The DA9058 is a low power Power Management Integrated Circuit with extra
functionality. It is a Multi Function Device controlled only from an I2C
bus whose components can raise an interrupt request on a single IRQ line.

The driver for the DA9058 consists of a core (i2c) device driver that
instantiates the individual component device drivers for:

hwmon - 5 ADC channels
gpio - 2 available pins
onkey - 1 device
regulator - 4 BUCKS, 19 LDO and 3 fixed
rtc - low power clock
power - battery information

All the above six component device drivers depend on the 'core' driver,
which is number one in the patch series.

This driver has been tested on a Samsung SMDK6410 connected to a Dialog
DA9058 Evaluation Board via one GPIO and a 3-wire I2C connection.

All the components can be builtin to the kernel or compiled as modules.
As far as I can tell, all the latest APIs both for the core driver and
all the component drivers have been adhered to, but if I have missed
something please let me know.

Many thanks,
Anthony Olech, Dialog Semiconductor Ltd.
