2020-06-19power: supply: gpio-charger: Make gpios optionalSebastian Reichel
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.

2020-06-11dt-bindings: Remove more cases of 'allOf' containing a '$ref'Rob Herring
Another round of 'allOf' removals that came in this cycle. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Signed-off-by: Rob Herring <robh@kernel.org>

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.

Add: - trickle-charge-current-microamp: Some chargers have 3 charging stages. First one when battery is almost empty is often called as trickle-charge. Last state when battery has been "woken up" is usually called as fast-charge. In addition to this some chargers have a 'middle state' which ROHM BD99954 data-sheet describes as pre-charge. Some batteries can benefit from this 3-phase charging [citation needed]. Introduce trickle-charge-current-microamp so that batteries can give charging current limit for all three states. - precharge-upper-limit-microvolt: When battery voltage has reached certain limit we change from trickle-charge to next charging state (pre-charge for BD99954). Allow battery to specify this limit. - re-charge-voltage-microvolt: Allow giving a battery specific voltage limit for chargers which can automatically re-start charging when battery has discharghed down to this limit. - over-voltage-threshold-microvolt Allow specifying voltage threshold after which the battery is assumed to be faulty.

2020-03-31dt-bindings: Add missing 'additionalProperties: false'Rob Herring
Setting 'additionalProperties: false' is frequently omitted, but is important in order to check that there aren't extra undocumented properties in a binding. Ideally, we'd just add this automatically and make this the default, but there's some cases where it doesn't work. For example, if a common schema is referenced, then properties in the common schema aren't part of what's considered for 'additionalProperties'. Also, sometimes there are bus specific properties such as 'spi-max-frequency' that go into bus child nodes, but aren't defined in the child node's schema. So let's stick with the json-schema defined default and add 'additionalProperties: false' where needed. This will be a continual review comment and game of wack-a-mole.

2019-10-20power: supply: cpcap-charger: Limit voltage to 4.2V for batteryTony Lindgren
There have been some cases of droid4 battery bulging that seem to be related to being left connected to the charger for several weeks. It is suspected that the 4.35V charge voltage configured for the battery is too much in the long run, so lets limit the charge voltage to 4.2V. It could also be that the batteries are just getting old. We don't really want to just change the charge voltage to 4.2V as Android may have charged the battery to 4.35V as pointed out by Pavel Machek. To add checks for battery voltage, the driver needs to understand the voltage it's charging at, and also needs to better understand it's charger state. Right now it only understands connect and disconnect, while now we need to know also a connected state but not charging. So let's add better charger state handling with help of chrgcurr2 interrupt for detecting charge full and retry, and add a check for battery voltage before we start charging. And then we finally can lower the charge voltage to 4.2V. Note that we've been using the same register values as the Android distros on droid4, so it is suspected that the same problem also exists in Android.
