Sebastian Reichel 972eabb97a Revert "power: supply: sbs-battery: simplify read_read_string_data"
The commit is a nice cleanup, but breaks booting on exynos5 based
chromebooks. It's seems to come down to exynos5's i2c driver not
implementing I2C_FUNC_SMBUS_READ_BLOCK_DATA. It's not yet clear
why that breaks boot / massively slows it down when userspace
starts, so revert the problematic patch.

This reverts commit c4b12a2f3f.

This depends on the simplification of sbs_read_string_data, which
breaks booting exynos5 based chromebooks. More investigation is
required, so this patch and the simplification patch are reverted
for this merge window.

Note, that this is only a partial revert, since sbs_update_presence()
has not been removed. It is also required for the charger broadcast
disabling.

Jean-Francois Dagenais 182fc88268 power: supply: sbs-battery: add ability to disable charger broadcasts
In certain designs, it is possible to add a battery on a populated i2c
bus without an sbs compliant charger. In that case, the battery will
unnecessarily and sometimes undesirably master the bus trying to write
info in the charger.

It is observed in many occasion that these battery "broadcasts" are even
corrupting other ongoing master to slave communication. I.e. the
multi-master support in the battery is inadequate.

Thankfully, the CHARGER_MODE bit allows designers to disable that SBS
battery behaviour.

This needs to be done once when the battery is first seen on the bus.

SBS batteries optionally have support for PEC. This enables
PEC handling based on the implemented SBS version as suggested

systems supporting batteries from different SBS generations.

Sebastian Reichel c4b12a2f3f power: supply: sbs-battery: simplify read_read_string_data
The SBS battery implements SMBus block reads. Currently the
driver "emulates" this by doing an I2C byte read for the
length followed by an I2C block read. The I2C subsystem
actually provides a proper API for doing SMBus block reads,
which can and should be used instead. The current implementation
does not properly handle packet error checking (PEC).

This change requires, that I2C bus drivers support I2C_M_RECV_LEN
or directly provide the SMBus API to access device manufacturer
and model name.

In the probe function, in case of error, resources allocated in

This can be achieved easily by using the devm_ variant of

This has the extra benefit to simplify the remove function and to axe the
