2020-06-02Revert "power: supply: sbs-battery: simplify read_read_string_data"Sebastian Reichel
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 c4b12a2f3f3de670f6be5e96092a2cab0b877f1a.

2020-06-02Revert "power: supply: sbs-battery: add PEC support"Sebastian Reichel
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.

2020-05-29power: supply: sbs-battery: add ability to disable charger broadcastsJean-Francois Dagenais
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.

2020-05-29power: supply: sbs-battery: simplify read_read_string_dataSebastian Reichel
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.
