Switch to using new gpio_desc interface and devm gpio get calls to automatically manage gpio resource. Use gpiod_get_value which handles active high / low calls. If gpio_detect is set then force loading of the driver as it is reasonable to assume that the battery may not be present. Update the is_present flag immediately in the IRQ.I queued PATCH 1-3. Please send a new revision for PATCH 4 (this one) with the following changes: * add the correct gpiod include: <include/linux/gpio/consumer.h> * rebase on power-supply's next branch * remove battery_detect and battery_detect_present from the struct sbs_platform_data and always use the gpiod API. It's data can also come from platform data, see Documentation/gpio/board.txt and Documentation/gpio/consumer.txt -- SebastianG'day Sebastian, Thanks, I'll have a look at how that works. I wasn't sure it was acceptable to change the interface to sbs_platform_data.
Yes, that API is not exposed by the kernel, so it can be changed. Since there are no users as far as I can see, changing it should be quite simple. Thanks for the driver cleanup. -- Sebastian
