Subject: [PATCH v2 0/1] power: supply: gpio-charger: Support to disable charger

From: Stefan Raufhake <s.raufhake@...khoff.de>

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.

Changes since v1:
=================

- Rework of the commit message
- Changed the property name from "charge-disable-gpios" to "enable-gpios".
- Inverted the logic of charge_type to 0 = disable and 1 = enable for the 
charger.
