Declare regulator_ops structure as const as it is only stored in the ops
field of a regulator_desc structure. This field is of type const, so
regulator_ops structures having this property can be made const too.

i2c_master_send() returns the number of bytes written on success.
So current code returns 2 if ad5398_write_reg() success.
This return value is propagated to .set_current_limit, .enable and .disable
callbacks of regulator_ops. This can be a problem, for example, if the
users test if the return value of regulator_set_current_limit() is 0.
Fix it by making ad5398_write_reg() return 0 on success.

The driver has a I2C device id table that is used to create the modaliases
and also "ad5398-regulator" is not a supported I2C id, so it's never used.

It is ok to request current limit with min_uA < chip->min_uA and
max_uA > chip->max_uA.
We need to set min_uA = chip->min_uA if (min_uA < chip->min_uA),
this ensures the equation to calcuate selator does not return negative number.
Also set max_uA = chip->max_uA if (max_uA > chip->max_uA), as suggested by
Sonic.

Rather than adding new arguments to regulator_register() every time we
want to add a new bit of dynamic information at runtime change the function
to take these via a struct. By doing this we avoid needing to do further
changes like the recent addition of device tree support which required each
regulator driver to be updated to take an additional parameter.
The regulator_desc which should (mostly) be static data is still passed
separately as most drivers are able to configure this statically at build
time.

Integer division may truncate the result.
Current code shows changing current is 0mA when selector is 1 ... 8.
For example:
selector = 1
ad5398_calc_current returns 117, debug message shows 117/1000 = 0mA
selector = 2
ad5398_calc_current returns 234, debug message shows 234/1000 = 0mA
selector = 3
ad5398_calc_current returns 351, debug message shows 351/1000 = 0mA
............
selector = 8
ad5398_calc_current returns 937, debug message shows 937/1000 = 0mA
Show the changing current in uA makes it easier for debugging.

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.

The AD5398 and AD5821 are single 10-bit DAC with 120 mA output current
sink capability. They feature an internal reference and operates from
a single 2.7 V to 5.5 V supply.
This driver supports both the AD5398 and the AD5821. It adapts into the
voltage and current framework.
