power: supply: axp20x_usb_power: enable USB BC detection on AXP813 (f2e5c49d) · Commits · 戴 / test

The AXP813 PMIC has support for detection of USB Battery Charging specification, and it will limit the current to 500mA by default when the detection is not enabled or the detection result is SDP. Enable the BC detection to allow correctly selection of the current. Signed-off-by:
