power: supply: sbs-battery: chromebook workaround for PEC
Looks like the I2C tunnel implementation from Chromebook's
embedded controller does not handle PEC correctly. Fix this
by disabling PEC for batteries behind those I2C tunnels as
a workaround.
Note, that some Chromebooks actually have been reported to
have working PEC support (with I2C tunnel). Since the problem
has not yet been fully understood this simply reverts all
Chromebooks to not use PEC for now.

Some Buffalo LinkStations perform the power off operation, at restart
time, depending on the state of an output pin (LED2/INTn) at the ethernet
PHY. This pin is also used to wake the machine when a WoL packet is
received by the PHY.
The driver is required by the Buffalo LinkStation LS421DE (ARM MVEBU),
and other models. Without it, the board remains forever halted if a
power off command is executed, unless the PSU is disconnected and
connected again.
Add the driver to provide the power off function and also make the WoL
feature to be available.

SBS batteries optionally have support for PEC. This enables
PEC handling based on the implemented SBS version as suggested
by the standard. The support for PEC is re-evaluated when the
battery is hotplugged into the system, since there might be
systems supporting batteries from different SBS generations.

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).
Not all upstream systems using sbs-battery have I2C bus drivers
supporting I2C_M_RECV_LEN, so old implementation is kept as
fallback to keep things working. But this prints a warning,
which hopefully results in people implementing support for it.

While strongly recommended, not all devices have a gpio to
detect if the charger is connected. This moves the 'gpios'
from required to optional section.
This also modifies error handling for the GPIO a bit: We
no longer fallback to pdata, if a GPIO is specified using
GPIO descriptor tables. This is a bit cleaner and does
not have any real impact: There are only two mainline pdata
users (arm/mach-sa1100/collie.c, arm/mach-pxa/tosa.c) and
none of them specify the GPIO via gpiod descriptor tables.
Once both have been converted the driver's support for
specifying GPIOs numbers in pdata will be dropped.

There is ongoing cleanup for the integrator, tegra, imx, and omap2
platforms, with integrator getting very close to the goal of having
zero code in arch/arm/, and omap2 moving more of the chip specifics

The Versatile Express platform is made more modular, with built-in

for the Android OS to have a common kernel binary for all platforms and

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.
This reverts commit 79bcd5a4a6.

Switch from DT specific of_property_* API to generic and more

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.

it might simply be idle and should be marked accordingly.

SBS batteries optionally have support for PEC. This enables
PEC handling based on the implemented SBS version as suggested
by the standard. The support for PEC is re-evaluated when the
battery is hotplugged into the system, since there might be
systems supporting batteries from different SBS generations.

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.
