* power: supply: bq27xxx: Stop and start delayed work in suspend and resumeMarek Vasut2023-11-151-0/+1
| | | | | | | | | | | | | | | | | | This driver uses delayed work to perform periodic battery state read out. This delayed work is not stopped across suspend and resume cycle. The read out can occur early in the resume cycle. In case of an I2C variant of this hardware, that read out triggers I2C transfer. That I2C transfer may happen while the I2C controller is still suspended, which produces a WARNING in the kernel log. Fix this by introducing trivial PM ops, which stop the delayed work before the system enters suspend, and schedule the delayed work right after the system resumes.

* power: supply: bq27xxx: Ensure power_supply_changed() is called on current ↵Hans de Goede2023-05-081-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | sign changes On gauges where the current register is signed, there is no charging flag in the flags register. So only checking flags will not result in power_supply_changed() getting called when e.g. a charger is plugged in and the current sign changes from negative (discharging) to positive (charging). This causes userspace's notion of the status to lag until userspace does a poll. And when a power_supply_leds.c LED trigger is used to indicate charging status with a LED, this LED will lag until the capacity percentage changes, which may take many minutes (because the LED trigger only is updated on power_supply_changed() calls). Fix this by calling bq27xxx_battery_current_and_status() on gauges with a signed current register and checking if the status has changed.

* power: supply: bq27xxx: Fix poll_interval handling and races on removeHans de Goede2023-05-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch bq27xxx_battery_teardown() was setting poll_interval = 0 to avoid bq27xxx_battery_update() requeuing the delayed_work item. There are 2 problems with this: 1. If the driver is unbound through sysfs, rather then the module being rmmod-ed, this changes poll_interval unexpectedly 2. This is racy, after it being set poll_interval could be changed before bq27xxx_battery_update() checks it through /sys/module/bq27xxx_battery/parameters/poll_interval Fix this by added a removed attribute to struct bq27xxx_device_info and using that instead of setting poll_interval to 0. There also is another poll_interval related race on remove(), writing /sys/module/bq27xxx_battery/parameters/poll_interval will requeue the delayed_work item for all devices on the bq27xxx_battery_devices list and the device being removed was only removed from that list after cancelling the delayed_work item. Fix this by moving the removal from the bq27xxx_battery_devices list to before cancelling the delayed_work item.

* power: supply: generic-adc-battery: use simple-battery APISebastian Reichel2023-03-291-18/+0
| | | | | | | | | | | | | | | | | Constant battery data is available through power-supply's simple-battery API. This works automatically, so the manual handling can be removed without loosing any feature :) Note, that the POWER_SUPPLY_STATUS_FULL check for the level variable can be dropped, since the variable is never written. It can be re-introduced properly once the driver gets functionality to calculate the current charge level. Apart from that the check must be done fuzzy anyways, since charge estimation usually is not precise enough to always return exactly the full charge capacity for a full battery.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the smartreflex device, we need to disable smartreflex on SoC idle, and have been using pm_runtime_irq_safe() to do that. But we want to remove the irq_safe usage as PM runtime takes a permanent usage count on the parent device with it. In order to remove the need for pm_runtime_irq_safe(), let's gate the clock directly in the driver. This removes the need to call PM runtime during idle, and allows us to switch to using CPU_PM in the following patch. Note that the smartreflex interconnect target module is configured for smart idle, but the clock does not have autoidle capability, and needs to be gated manually. If the clock supported autoidle, we would not need to even gate the clock. With this change, we can now remove the related quirk flags for ti-sysc also.

| | | | | | | | | | | | | | | | | | | | | On all newer bq27xxx ICs, the AveragePower register contains a signed value; in addition to handling the raw value as unsigned, the driver code also didn't convert it to µW as expected. At least for the BQ28Z610, the reference manual incorrectly states that the value is in units of 1mW and not 10mW. I have no way of knowing whether the manuals of other supported ICs contain the same error, or if there are models that actually use 1mW. At least, the new code shouldn't be *less* correct than the old version for any device. power_avg is removed from the cache structure, se we don't have to extend it to store both a signed value and an error code. Always getting an up-to-date value may be desirable anyways, as it avoids inconsistent current and power readings when switching between charging and discharging.
