For a better performance in USB charging operation, the DA9052/53 charging current can be configured in accordance with the USB host current delivering capacity (known through USB drivers negotiation). To implement this useful feature, a new writable property "USB charge current" needs to be added in the Linux battery core.

Let me know your views on it.

that's the wrong way to do it. What we need is to use the transceiver notifications to notify every time someone calls usb_gadget_vbus_draw() and pass the mA parameter as argument to the event notification.

Charger driver should 'subscribe' to transceiver notifications and use the mA argument to reconfigure charging.
