From fafedff35015c8cca7c537b68deb57b22c3ead73 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Tue, 17 Oct 2023 14:12:44 +0100 Subject: [PATCH] power: regulator: add AXP313 support The X-Powers AXP313a is a small PMIC with just three buck converters and three LDOs, one of which is actually fixed (so not modelled here). Add the compatible string and the respective regulator ranges to allow drivers to adjust voltages.
