Sebastian Reichel 436ff8c928 power: supply: sbs-manager: use dev_err_probe
Introduce usage of dev_err_probe in probe routine, which
makes the code slightly more readable and removes some
lines of code. It also removes PROBE_DEFER errors being
logged by default.

We have a dedicated pointer for that, so use it. Much easier to read and
less computation involved.

Phil Reid a0b8839e2a power: supply: sbs-manager: Add alert callback and battery change notification
This adds smb alert support via the smbus_alert driver to generate
power_supply_changed notifications when either external power is
removed / applied or a battery inserted / removed.
Use the i2c alert callback to notify the attached battery driver that a
change has occurred.

Karl-Heinz Schneider dbc4deda03 power: Adds support for Smart Battery System Manager
This patch adds support for Smart Battery System Manager.
A SBSM is a device listening at I2C/SMBus address 0x0a and is capable of
communicating up to four I2C smart battery devices. All smart battery
devices are listening at address 0x0b, so the SBSM muliplexes between
them. The driver makes use of the I2C-Mux framework to allow smart
batteries to be bound via device tree, i.e. the sbs-battery driver.

Via sysfs interface the online state and charge type are presented. If
the driver is bound as ltc1760 (an implementation of a Dual Smart Battery
System Manager) the charge type can also be changed from trickle to fast.
