2020-12-12power: supply: ab8500_charger: Oneshot threaded IRQsLinus Walleij
Make sure the threaded IRQs requested by the charger are flagged as "oneshot". Usually this is what you want, and since the interrupts are shared with the USB phy on the AB8500 we will get a conflict like this if we don't, since the phy request them threaded oneshot: genirq: Flags mismatch irq 83. 00004084 (USB_LINK_STATUS vs. 00006084 (usb-link-status) ab8500-charger ab8500-charger.0: failed to request USB_LINK_STATUS IRQ 83: -16 Cc: Marcus Cooper <codekipper@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>

2020-11-30power: supply: axp288_charger: Fix HP Pavilion x2 10 DMI matchingHans de Goede
Commit 9c80662a74cd ("power: supply: axp288_charger: Add special handling for HP Pavilion x2 10") added special handling for HP Pavilion x2 10 models which use the weird combination of a Type-C connector and the non Type-C aware AXP288 PMIC. This special handling was activated by a DMI match a the product-name of "HP Pavilion x2 Detachable". Recently I've learned that there are also older "HP Pavilion x2 Detachable" models with an AXP288 PMIC + a micro-usb connector where we should not activate the special handling for the Type-C connectors. Extend the matching to also match on the DMI board-name and match on the 2 boards (one Bay Trail based one Cherry Trail based) of which we are certain that they use the AXP288 + Type-C connector combination. Note the DSDT code from these older (AXP288 + micro-USB) models contains some AML code (which never runs under Linux) which reads the micro-USB connector id-pin and if it is pulled to ground, which would normally mean the port is in host mode!, then it sets the input-current-limit to 3A, it seems HP is using the micro-USB port as a charging only connector and identifies their own 3A capable charger though this hack which is a major violation of the USB specs. Note HP also hardcodes a 2A limit when the id-pin is not pulled to ground, which is also in violation of the specs. I've no intention to add support for HP's hack to support 3A charging on these older models. By making the DMI matches for the Type-C equipped models workaround more tighter, these older models will be treated just like any other AXP288 + micro-USB equipped device and the input-current limit will follow the BC 1.2 spec (using the defacto standard values there where the BC 1.2 spec defines a range).

2020-10-03power: supply: max17040: Support soc alertIskren Chernev
max17048 and max17049 support SOC alerts (interrupts when battery capacity changes by +/- 1%). At the moment the driver polls for changes every second. Using the alerts removes the need for polling.

2020-10-03power: supply: max17040: Support setting rcompIskren Chernev
The Maxim ModelGauge family supports fine-tuning by setting a compensation value (named rcomp in the docs). The value is affected by battery chemistry and ambient temperature. Add support for reading maxim,rcomp from DT and configuring the device with the supplied value. Temperature adjustment is not implemented at the moment, because there is no provision for receiving the ambient temperature at the moment.

2020-10-03power: supply: max17040: Support compatible devicesIskren Chernev
The max17040 fuel gauge is part of a family of 8 chips that have very similar mode of operations and registers. This change adds: - compatible strings for all supported devices and handling for the minor differences between them; - handling for devices reporting double capacity via maxim,double-soc; The datasheets of the supported devices are linked [0] [1] [2] [3].
