2023-01-16power: remove s3c adc battery driverArnd Bergmann1-453/+0
The s3c-adc driver is removed along with the s3c24xx platform, so the battery driver is no longer needed either. Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Acked-by: Sebastian Reichel <sebastian.reichel@collabora.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2021-04-08power: supply: s3c_adc_battery: fix possible use-after-free in ↵Yang Yingliang1-1/+1
s3c_adc_bat_remove() This driver's remove path calls cancel_delayed_work(). However, that function does not wait until the work function finishes. This means that the callback function may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling cancel_delayed_work_sync(), which ensures that the work is properly cancelled, no longer running, and unable to re-schedule itself.

2020-11-30power: supply: s3c-adc-battery: Convert to GPIO descriptorsLinus Walleij1-28/+29
This converts the S3C ADC battery to use GPIO descriptors instead of a global GPIO number for the charging completed GPIO. Using the pattern from the GPIO charger we name this GPIO line "charge-status" in the board file.

2020-08-19ARM: s3c: adc: move header to linux/soc/samsungArnd Bergmann1-1/+1
There are multiple drivers using the private adc interface. It seems unlikely that they would ever get converted to iio, so make the current state official by making the header file global. The s3c2410_ts driver needs a couple of register definitions as well.

For power_supply_get_drvdata() routine to work correctly the driver data has to be provided when registering power supply, otherwise driver gives up immediately with these errors: power_supply main-battery: no battery infos ?! power_supply main-battery: driver failed to report `status' property: -22 Signed-off-by: Sergiy Kibrik <sakib@darkstar.site> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
2016-08-11power: move power supply drivers to power/supplySebastian Reichel1-0/+459
This moves all power supply drivers from drivers/power/ to drivers/power/supply/. The intention is a cleaner source tree, since drivers/power/ also contains frameworks unrelated to power supply, like adaptive voltage scaling. Signed-off-by: Sebastian Reichel <sre@kernel.org>
