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. Across platforms, there is ongoing cleanup, with Geert and Rob revisiting some a lot of Kconfig options" * tag 'arm-soc-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (94 commits) ARM: omap2: fix omap5_realtime_timer_init definition ARM: zynq: Don't select CONFIG_ICST ARM: OMAP2+: Fix regression for using local timer on non-SMP SoCs clk: versatile: Fix kconfig dependency on COMMON_CLK_VERSATILE ARM: davinci: fix build failure without I2C power: reset: vexpress: fix build issue power: vexpress: cleanup: use builtin_platform_driver power: vexpress: add suppress_bind_attrs to true Revert "ARM: vexpress: Don't select VEXPRESS_CONFIG" MAINTAINERS: pxa: remove Compulab arm/pxa support ARM: pxa: remove Compulab pxa2xx boards bus: arm-integrator-lm: Fix return value check in integrator_ap_lm_probe() soc: imx: move cpu code to drivers/soc/imx ARM: imx: move cpu definitions into a header ARM: imx: use device_initcall for imx_soc_device_init ARM: imx: pcm037: make pcm970_sja1000_platform_data static bus: ti-sysc: Timers no longer need legacy quirk handling ARM: OMAP2+: Drop old timer code for dmtimer and 32k counter ARM: dts: Configure system timers for omap2 ARM: dts: Configure system timers for ti81xx ...

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.

2020-06-02Revert "power: supply: sbs-battery: add PEC support"Sebastian Reichel1-51/+0
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 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.

2020-05-29power: supply: sbs-battery: simplify read_read_string_dataSebastian Reichel1-53/+12
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.

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.

2020-05-10power: bq25890: use proper CURRENT_NOW property for I_BATMichał Mirosław1-10/+10
Charge Current is more apropriately reflected by CURRENT_NOW property (measured current) than CONSTANT_CURRENT_VOLTAGE (configured CC-phase current limit). Fix the reference and make the sign reflect direction of the current. Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
2020-05-10power: supply: max17040: Correct voltage readingJonathan Bakker1-1/+1
According to the datasheet available at (1), the bottom four bits are always zero and the actual voltage is 1.25x this value in mV. Since the kernel API specifies that voltages should be in uV, it should report 1250x the shifted value. 1) https://datasheets.maximintegrated.com/en/ds/MAX17040-MAX17041.pdf Signed-off-by: Jonathan Bakker <xc-racer2@live.ca> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
