2021-08-06power: supply: max17042_battery: Add support for MAX77849 Fuel-GaugeNikita Travkin
MAX77849 is a combined fuel-gauge, charger and MUIC IC. Notably, fuel-gauge has dedicated i2c lines and seems to be fully compatible with max17047. Add new compatible for it reusing max17047 code paths. Signed-off-by: Nikita Travkin <nikita@trvn.ru> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
2021-08-05power: supply: axp288_fuel_gauge: Take the P-Unit semaphore only once during ↵Hans de Goede
probe() The I2C-bus to the XPower AXP288 is shared between the Linux kernel and the SoCs P-Unit. The P-Unit has a semaphore which the kernel must "lock" before it may use the bus. If not explicitly taken by the I2C-driver, then this semaphore is automatically taken by the I2C-bus-driver for each I2C-transfer and this is a quite expensive operation. Explicitly take the semaphore in probe() around the register-accesses done during probe, so that this only needs to be done once, rather then once per register-access.

2021-08-05power: supply: axp288_fuel_gauge: Refresh all registers in one goAndrejus Basovas
The I2C-bus to the XPower AXP288 is shared between the Linux kernel and the SoCs P-Unit. The P-Unit has a semaphore which the kernel must "lock" before it may use the bus and while the kernel holds the semaphore the CPU and GPU power-states must not be changed otherwise the system will freeze. This is a complex process, which is quite expensive. This is all done by iosf_mbi_block_punit_i2c_access(). To ensure that no unguarded I2C-bus accesses happen, iosf_mbi_block_punit_i2c_access() gets called by the I2C-bus-driver for every I2C transfer. Because this is so expensive it is allowed to call iosf_mbi_block_punit_i2c_access() in a nested fashion, so that higher-level code which does multiple I2C-transfers can call it once for a group of transfers, turning the calls done by the I2C-bus-driver into no-ops. Userspace power-supply API users typically will read all provided properties in one go, refreshing the last read values when power_supply_changed() is called by the driver and/or periodically (e.g. every 2 minutes). The reading of all properties in one go causes the P-Unit semaphore to quickly be taken and released multiple times in a row. Certain PMIC registers like AXP20X_FG_RES are even used in multiple properties so they get read multiple times, leading to a P-Unit take + release each time the register is read. As already mentioned the taking of the P-Unit semaphore is a quite expensive operation and it has also been reported that the "hammering" of the P-Unit semaphore done by the axp288_fuel_gauge driver can even cause stability issues with the system as a whole. Switch over to a scheme where the axp288_fuel_gauge driver keeps a local copy of all the registers which it uses for properties and make it only refresh its copy of the registers if the values are older then 1 minute; or when a fuel-gauge interrupt has triggered since the last read. This not only reduces the amount of reads, it also makes the code do all the reads in one go, rather then reading specific registers based on which property is being queried. This allows calling iosf_mbi_block_punit_i2c_access() once before doing all the reads, so that we now only take the P-Unit semaphore once per update.

2021-08-05power: supply: axp288_fuel_gauge: Only read PWR_OP_MODE, FG_LOW_CAP_REG regs ↵Hans de Goede
once Accessing registers on the AXP288 is quite expensive, so we should avoid doing unnecessary accesses. The FG_LOW_CAP_REG never changes underneath us, so we only need to read it once. Devices with an AXP288 do not have user-replace (let alone hot-swappable) batteries and the only bit we care about in the PWR_OP_MODE register is the CHRG_STAT_BAT_PRESENT bit, so we can get away with only reading the PWR_OP_MODE register once too. Note that the FG_LOW_CAP_REG is not marked volatile in the regmap, so we were effectively already reading it once. This change makes this explicit, this is done as preparation of a further patch which moves all remaining register accesses in fuel_gauge_get_property() out of that function.

2021-08-05power: supply: axp288_fuel_gauge: Drop retry logic from fuel_gauge_reg_readb()Hans de Goede
The I2C-bus to the XPower AXP288 is shared between the Linux kernel and the SoCs P-Unit. The P-Unit has a semaphore which the kernel must "lock" before it may use the bus. This semaphore is automatically taken by the I2C-bus-driver. The retry on -EBUSY logic in fuel_gauge_reg_readb() likely was added to deal with the I2C-bus-drive returning -EBUSY when it failed to take the semaphore, but this really should never happen. The semaphore code even has a WARN_ON(ret) to log a kernel backtrace if this does somehow happen, when this happens something is seriously wrong and the system typically freezes soon afterwards. TL;DR: the regmap_read() should never fail with -EBUSY so the retries are unnecessary.

2021-08-05power: supply: axp288_fuel_gauge: Remove debugfs supportHans de Goede
The debugfs code is simply just dumping a bunch of registers, the same information can also easily be gotten through the regmap debugfs interface or through the i2cdump utility. I've not used the debugfs interface once in all these years that I've been working on the axp288_fuel_gauge driver, so lets just remove it. Note this also removes the temperature-channels from the list of IIO ADC channels used by the driver, since these were only used in the debugfs interface.

This branch also contains a few of the fixes that weren't sent in by the end of the release (all fairly minor). - Adding an additional maintainer for the TEE subsystem (Sumit Garg) - Quite a significant modernization of the IXP4xx platforms by Linus Walleij, revisiting with a new PCI host driver/binding, removing legacy mach/* include dependencies and moving platform detection/config to drivers/soc. Also some updates/cleanup of platform data. - Core power domain support for Tegra platforms, and some improvements in build test coverage by adding stubs for compile test targets. - A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP support on i.MX7D, SoC ID setup for i.MX50, removal of platform data and board fixups for iMX6/7. ... and a few smaller changes and fixes for Samsung, OMAP, Allwinner, Rockchip" * tag 'arm-soc-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (53 commits) MAINTAINERS: Add myself as TEE subsystem reviewer ixp4xx: fix spelling mistake in Kconfig "Devce" -> "Device" hw_random: ixp4xx: Add OF support hw_random: ixp4xx: Add DT bindings hw_random: ixp4xx: Turn into a module hw_random: ixp4xx: Use SPDX license tag hw_random: ixp4xx: enable compile-testing pata: ixp4xx: split platform data to its own header soc: ixp4xx: move cpu detection to linux/soc/ixp4xx/cpu.h PCI: ixp4xx: Add a new driver for IXP4xx PCI: ixp4xx: Add device tree bindings for IXP4xx ARM/ixp4xx: Make NEED_MACH_IO_H optional ARM/ixp4xx: Move the virtual IObases MAINTAINERS: ARM/MStar/Sigmastar SoCs: Add a link to the MStar tree ARM: debug: add UART early console support for MSTAR SoCs ARM: dts: ux500: Fix LED probing ARM: imx: add smp support for imx7d ARM: imx6q: drop of_platform_default_populate() from init_machine arm64: dts: rockchip: Update RK3399 PCI host bridge window to 32-bit address memory soc/tegra: fuse: Fix Tegra234-only builds ...
2021-07-10rtc: pcf2127: handle timestamp interruptsMian Yousaf Kaukab
commit 03623b4b041c ("rtc: pcf2127: add tamper detection support") added support for timestamp interrupts. However they are not being handled in the irq handler. If a timestamp interrupt occurs it results in kernel disabling the interrupt and displaying the call trace: [ 121.145580] irq 78: nobody cared (try booting with the "irqpoll" option) ... [ 121.238087] [<00000000c4d69393>] irq_default_primary_handler threaded [<000000000a90d25b>] pcf2127_rtc_irq [rtc_pcf2127] [ 121.248971] Disabling IRQ #78 Handle timestamp interrupts in pcf2127_rtc_irq(). Save time stamp before clearing TSF1 and TSF2 flags so that it can't be overwritten. Set a flag to mark if the timestamp is valid and only report to sysfs if the flag is set. To mimic the hardware behavior, don’t save another timestamp until the first one has been read by the userspace. However, if the alarm irq is not configured, keep the old way of handling timestamp interrupt in the timestamp0 sysfs calls.

2021-07-10rtc: at91sam9: Remove unnecessary offset variable checksNobuhiro Iwamatsu
The offset variable is checked by at91_rtc_readalarm(), but this check is unnecessary because the previous check knew that the value of this variable was not 0. This removes that unnecessary offset variable checks.
