The SMB349 charger chip allows charge batteries
with a higher current. Add this driver to be able to
control charging from kernel space and deliver charging
information to userspace.
Also add debugfs entries to show current register
settings of SMB349 charger.

Until now only the BMS system was using the ccadc so there was
no need to create a separate ccadc driver.
However we can run in a configuration with BMS disabled
and clients won't be able to read battery current via ccadc.
Separate the ccadc from the bms, this change in is preparation
to add a ccadc api to read the battery current.

Move the following subdevices to use the pm8xxx interface -
mpp, irq, gpio, keypad, power-key, leds, othc, vibrator,
rtc, batt-alarm, thermal, upl, nfc, pwm, xoadc, regulators,
xo-buffers, charger.
This allows usage of a common driver for modules which are same
across multiple PM8XXX PMICs. It also provides flexibility
to add/remove subdevices for multiple board configurations.

The isl9519q interface with the pm8921 via external-charger registration.
The pm8921 notifies the isl9519q to start/stop charging.
This way the isl9519q driver doesn't need to:
1. Monitor the charge current for end-of-charging detection.
2. Get interrupt from isl9519q HW.
3. Check n_valid_gpio for DC Inserted validity.

It was suggested to combine this functionality with the current ds2782

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.

This patch adds support for the bq27000 battery to the bq27x00 driver.
The bq27000 is similar to the bq27200 except that it uses the HDQ bus
instead of I2C to communicate with the host system.
The driver is implemented as a platform driver. The driver expects to be
provided with a read callback function through its platform data. The read
function is assumed to do the lowlevel HDQ handling and read out the value
of a certain register.

The MAX17042 is a fuel gauge with an I2C interface for lithium-ion
betteries. Unlike its predecessor MAX17040, MAX17042 uses 16bit
registers. Besides, MAX17042 has much more features than MAX17040; e.g.,
a thermistor, current and current accumulation measurement, battery
internal resistance estimate, average values of measurement, and others.
This patch implements a driver for MAX17042.
In this initial release, we have implemented the most basic features of
a fuel gauge: measure the battery capacity and voltage.

This patch adds support for the PMU provided by the WM8350 which
implements battery, line and USB supplies including a battery charger.
The hardware functions largely autonomously, with minimal software
control required to initiate fast charging.
Support for configuration of the USB supply is not yet implemented.
This means that the hardware will remain in the mode configured at
startup, by default limiting the current drawn from USB to 100mA.
This driver was originally written by Liam Girdwood with subsequent
updates for submission by Mark Brown.

is designed in order to easily allow the HDQ chip version integration.
