Hi Piotr Wilczek,
Nice idea to have a generic function.
Just have some minor comments.

0xff is for?
I guess this is a array of Buck control 1 registers so we can be
specific in naming the same instead of just buck address.
Any way we have address for them defined as a enum in
include/power/max77686_pmic.h cant we use the same?

Cant we get the ldo addresses directly as they are available in the
include file.
Then top check would also go off.

This is an array of address of every Buck control 1 register.
When the user specifies which Buck number he wants to change, the driver
figures out the address from the array.
If the address is given directly it is still necessary to get the correct
mode hex value depending on the address.

Only to stress it is a const, I will change it.

When code execution reach here, wrong voltage value is given.
With printf it will be immediately known that there is something wrong, but
I can change it to debug.

Well, I decided that is better that user specifies the ldo (or buck) number
and the driver figures out the address to write and also the hex value for
the mode or voltage. What do you think?
Please note that in every case it is necessary to get ldo number from the
address (or directly check the address) to get the correct hex value to
write to register.
The top check is not really necessary, but for a very little cost of
performance it makes the code safer.

commit c18222bee868ae65a878165551d3d407c402f48c
Author: Ajay Kumar <ajaykumar.rs@samsung.com>
Date: Thu Feb 21 23:52:58 2013 +0000
video: exynos_dp: Remove callbacks from the driver
Replaced the functionality of callbacks by using a standard set of functions.
Instead of implementing and hooking up a callback, put the same code in one of
the standard set of functions by overriding it.
Please check latest version on u-boot-samsung.
