2022-06-18iio:light:tsl2563: Replace cancel_delayed_work() with ↵Tetsuo Handa1-2/+2
cancel_delayed_work_sync(). Since cancel_delayed_work(&chip->poweroff_work) does not guarantee that tsl2563_poweroff_work() is not running, tsl2563_set_power(chip, 0) can be called from tsl2563_poweroff_work() after tsl2563_get_power(chip) and tsl2563_set_power(chip, 1) are called. Use _sync version in order to make sure that tsl2563_poweroff_work() is no longer running.

2022-06-18iio: light: tsl2563: Replace flush_scheduled_work() with ↵Tetsuo Handa1-2/+1
cancel_delayed_work_sync(). Commit 9e61d901155bcd4e ("iio: light: tsl2563: Remove flush_scheduled_work") replaced cancel_delayed_work() + flush_scheduled_work() with cancel_delayed_work_sync() for only tsl2563_probe() side. Do the same thing for tsl2563_remove() side, which was added by commit 388be4883952872b ("staging:iio: tsl2563 abi fixes and interrupt handling").

2022-06-18iio: trigger: warn about non-registered iio trigger getting attemptDmitry Rokosov1-0/+2
As a part of patch series about wrong trigger register() and get() calls order in the some IIO drivers trigger initialization path: https://lore.kernel.org/all/20220524181150.9240-1-ddrokosov@sberdevices.ru/ runtime WARN_ONCE() is added to alarm IIO driver authors who make such a mistake. When an IIO driver allocates a new IIO trigger, it should register it before calling the get() operation. In other words, each IIO driver must abide by IIO trigger alloc()/register()/get() calls order.

2022-06-18iio: adc: qcom-spmi-rradc: introduce round robin adcCaleb Connolly3-0/+1035
The Round Robin ADC is responsible for reading data about the rate of charge from the USB or DC input ports, it can also read the battery ID (resistence), skin temperature and the die temperature of the pmic. It is found on the PMI8998 and PM660 Qualcomm PMICs.

2022-06-18mfd: qcom-spmi-pmic: expose the PMIC revid information to clientsCaleb Connolly1-90/+175
Some PMIC functions such as the RRADC need to be aware of the PMIC chip revision information to implement errata or otherwise adjust behaviour, export the PMIC information to enable this. This is specifically required to enable the RRADC to adjust coefficients based on which chip fab the PMIC was produced in, this can vary per unique device and therefore has to be read at runtime.
