Pull power supply and reset updates from Sebastian Reichel:
 "New drivers:
   - Linear ltc3651 charger driver
   - Motorola CPCAP battery fuel-gauge driver

  New chip/feature support:
   - bq27xxx: prepare for chip data setup
   - axp20x_battery: support max charge current setup

  New core features:
   - add Apple Brick ID type
   - support "supplied-from" device property for generic ACPI/pdata support
   - support strings for sysfs properties representing enums
   - introduce battery-info (backend is DT only for now)
   - provide reboot-mode header globally

  .. and misc fixes"

power: supply: twl4030-charger: add deferred probing for phy and iio

2017-07-03T17:15:22+00:00

This fixes an issue if both this twl4030_charger driver and
phy-twl4030-usb are compiled as modules and loaded in random order.

It has been observed on GTA04 and OpenPandora devices that in worst
case the boot process hangs and in best case the AC detection fails
with a warning.

Therefore we add deferred probing checks for the usb_phy and the
iio channel for AC detection.

power: supply: twl4030-charger: move irq allocation to just before irqs are enabled

2017-07-03T17:15:00+00:00

And initialize workers and notifiers as soon as possible.

This avoids a potential race if irqs are enabled and triggered too early
before the worker is properly set up.

power: supply: sbs-battery: Don't needlessly set CAPACITY_MODE

2017-06-15T14:52:04+00:00

According to the smart battery spec (1), the CAPACITY_MODE bit does not
influence the value read from RelativeStateOfCharge(), so don't bother
changing CAPACITY_MODE when doing such a read.

power: supply: sbs-battery: Prevent CAPACITY_MODE races

2017-06-15T14:51:25+00:00

A subset of smart battery commands return charge or energy depending on
the CAPACITY_MODE bit setting of BatteryMode(). In order to
unambiguously read a charge or energy value, it is necessary to ensure
that CAPACITY_MODE is set as desired, and not changed for the duration
of the attribute read.

power: supply: bq24735: remove incorrect le16_to_cpu calls

2017-06-15T14:47:35+00:00

i2c_smbus commands handle the correct byte order for smbus transactions
internally. This will currently result in incorrect operation on big
endian systems.

2017-06-15T08:16:59+00:00

Otherwise cpcap-battery won't probe properly with the power-supplies
property configured but will fail with "Not all required supplies found,
defer probe".

power: supply: twl4030-charger: move allocation of iio channel to the beginning

2017-06-14T20:10:44+00:00

This is in prepraration for EPROBE_DEFER handling because it is quite
likely that geting the (madc) iio channel is deferred more often than
later steps.
