The ONLINE prop should be when the charger is present (ie able to charge), however, it was for when it was actually charging or not. Instead, add the STATUS prop to show whether charging is actually going on or not. The magic numbers have been ported from a downstream kernel for the SGH-T959V.

2020-06-19power: supply: bq24190_charger: Fix runtime PM imbalance on errorDinghao Liu1-1/+3
pm_runtime_get_sync() increments the runtime PM usage counter even it returns an error code. Thus a pairing decrement is needed on the error handling path to keep the counter balanced.

2020-06-19power: supply: sbs-battery: add PEC supportSebastian Reichel1-3/+61
SBS batteries optionally have support for PEC. This enables PEC handling based on the implemented SBS version as suggested by the standard.

2020-06-19power: supply: sbs-battery: use i2c_smbus_read_block_data()Sebastian Reichel1-2/+29
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. Tested-by: Marek Szyprowski <[email protected]> Signed-off-by: Sebastian Reichel <[email protected]>
2020-06-19power: supply: gpio-charger: Make gpios optionalSebastian Reichel1-13/+25
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.

Pull ARM SoC updates from Arnd Bergmann: "One new platform gets added, the Realtek RTD1195, which is an older Cortex-a7 based relative of the RTD12xx chips that are already supported in arch/arm64. The platform may also be extended to support running 32-bit kernels on those 64-bit chips for memory-constrained machines. In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally released in 2016 as one of the last high-end 32-bit designs. 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 from old board code into device tree files. The Versatile Express platform is made more modular, with built-in drivers now becoming loadable modules. This is part of a greater effort for the Android OS to have a common kernel binary for all platforms and any platform specific code in loadable modules. The PXA platform drops support for Compulab's pxa2xx boards that had rather unusual flash and PCI drivers but no known users remaining. All device drivers specific to those boards can now get removed as well.

2020-06-02Revert "power: supply: sbs-battery: simplify read_read_string_data"Sebastian Reichel1-12/+53
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.

More investigation is required, so this patch and the simplification patch are reverted for this merge window.

2020-05-29power: supply: sbs-battery: add ability to disable charger broadcastsJean-Francois Dagenais1-0/+29
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.

2020-05-10power: bq25890: fix ADC mode configurationMichał Mirosław1-5/+26
Datasheet describes two modes for reading ADC measurements: 1. continuous, 1 Hz - enabled and started by CONV_RATE bit 2. one-shot - triggered by CONV_START bit In continuous mode, CONV_START is read-only and signifies an ongoing conversion. Change the code to follow the datasheet and really disable continuous mode for power saving. Signed-off-by: Michał Mirosław <[email protected]> Signed-off-by: Sebastian Reichel <[email protected]>
