From 3b142fdcae780cb67ab4cab61cf71647e9566411 Mon Sep 17 00:00:00 2001 From: Mithil Bavishi Date: Tue, 3 Mar 2026 15:30:10 -0500 Subject: [PATCH 01/12] ARM: dts: twl6032: Add DTS file for TWL6032 PMIC Add a dedicated DTS file for the TWL6032 PMIC (Phoenix Lite). Already has driver support with TWL6030 (Phoenix) since both of them are so similar, some nodes can be reused from TWL6030 as well This can be included in the board files like twl6030 Example: ... &i2c1 { twl: twl@48 { reg = <0x48>; interrupts = ; interrupt-controller; interrupt-parent = <&gic>; }; }; /include/ "twl6032.dtsi" ...
