From af1dcd3d2d37c85b7ff9315227a5cf28e1b80d1b Mon Sep 17 00:00:00 2001 From: Aidan MacDonald Date: Wed, 10 May 2023 12:50:45 +0100 Subject: [PATCH] power: supply: axp20x_usb_power: Add support for AXP192 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).
