[PATCH v1 6/7] power: supply: axp20x_usb_power: Add support for AXP192

From: Aidan MacDonald
Date: Wed May 10 2023 - 07:52:09 EST


Add support for the AXP192. It is most similar to the AXP202 but
the current limits are different and the USB OTG status register
has a different address (0x04 instead of 0x02).
