In include/linux/mfd/mc13892.h, we define MC13892_VCOINCELL as 23.
Thus VCOINCELL should be defined as 23th element in mc13892_regulators array, not the first one.
This actually fixes an off-by-one bug while accessing mc13892_regulators array.

For example,
In mc13892_regulator_probe, we use MC13892_VCAM as array index of mc13892_regulators array.
        mc13892_regulators[MC13892_VCAM].desc.ops->set_mode
                = mc13892_vcam_set_mode;
Currently, it access mc13892_regulators[12] ,which is VAUDIO not VCAM.

With TWL6030, it is not enough to ensure that the regulator is the
group of P1 group (CPU/Linux), but we need to check the state as far
as APP is concerned as well.

Split the current is_enabled to 6030 and 4030 specific ones. This
split impacts few macros and variables as well, but sets up the
stage for further fixes to set_mode and get_status in subsequent

TWL6030 does not have remap register. The current implementation
causes value of remap to be written to state register, accidentally
causing the regulators which are probed to be switched on as well.
This is wrong as regulators should be controllable based on calls
to enable/disable for TWL regulator framework. Further, the values
initialized make no sense as well. We hence remove this from the
initalizers and also write to remap register only if the TWL
is 4030.

TWL6030 requires an additional register write to CFG_STATE register

Add support for the Maxim/Dallas DS2780 Stand-Alone Fuel Gauge IC.

It was suggested to combine this functionality with the current ds2782
driver.  Unfortunately, I'm unable to commit the time to refactoring this
driver to that extent and I don't have a platform with the ds2782 part to
validate that there are no regression issues by adding this functionality.

The first patch adds generic functionnality to w1_io for Resume Command
[A5h] lots of slaves support.  I found it useful for multi-commands/reset
workflows with the same slave on a multi-slave bus.

This DS2408 w1 slave driver is not complete for all the features of the
chip, but its sufficient if you use it as a simple IO expander.  Enjoy!

The ds1wm had Kconfig dependencies towards ARM && HAVE_CLK.  I took them
out since I was using the ds1wm on an x86_64 platform (ds1wm in a FPGA
through pcie) and found them irrelevant.

The clock freq/divisors at the top of ds1wm.c did not have the MSB set to
1.  This bit is CLK_EN which turns the whole prescaler and dividers on.
The driver never mentionned this bit either, so I just included this bit
right in the table entries.  I also took the liberty to add a couple of
entries to the table.  The spec doesn't explicitely mentions these
possibilities but the description and examination of the core shows the
prescalers & dividers can be used for more than the table explicitely
shows.  The table I enlarged still doesn't cover all possibilities, but
it's a good start.

I also made a few tweaks to a couple of the read and write algorithms
which made sense while I had my head very deep in the ds1wm documentation.
 We stressed it a lot with 10+ slaves on the bus, many ds2408, ds2431 and
ds2433 at the same time doing extensive interaction.  It proved quite
stable in our production environment.

This patch:
