From: Stefan Raufhake <s.raufhake@beckhoff.com> Hello, We have a device with a simple built-in UPS, which is controlled by GPIOs. For the control of the UPS, we used the “gpio-charger” driver module from the power-supply. For our usecase we want to support enabing and disabling the ups. When the UPS is disabled, the device turns off immediately if the supply power is switched off. When the UPS is enabled, the device has power as long as the UPS has enough energy for the device. Now, we are looking for the best way to implement this function. This patch contains our first proposal.
