From 63eeabbc9dbddd7381409feccd9082e5ffabfe59 Mon Sep 17 00:00:00 2001 From: Aidan MacDonald Date: Thu, 11 May 2023 10:26:08 +0100 Subject: [PATCH] mfd: axp20x: Add support for AXP192 The AXP192 PMIC is similar to the AXP202/AXP209, but with different regulators, additional GPIOs, and a different IRQ register layout.
