Subject: [PATCH v2 0/2] power: supply: gpio-charger: add support for
 default charge current limit

With DT properties charge-current-limit-gpios and
charge-current-limit-mapping one can define charge current limits in uA
using up to 32 GPIOs. At the moment the driver defaults to smallest charge
current limitation for safety reasons. When disabling charging is
supported, which should be common, the driver defaults to non charging on
probe. By having a default, charging can be enabled on probe for such
devices.

Changes in v2:
- renamed DT property charge-current-limit-default to
  charge-current-limit-default-microamp
- Added dependency on charge-current-limit-mapping
- Added intention and use case to commit descriptions
- Added charge-current-limit-default-microamp in bindings example
- Link to v1: https://lore.kernel.org/r/20241211-default-charge-current-limit-v1-0-7819ba06ee2a@liebherr.com
