Subject: [PATCH v3 12/12] arm64: dts: mediatek: mt8183-kukui: Add PMIC regulator supplies
Date:   Tue, 19 Sep 2023 18:43:55 +0800

The PMIC regulator node is missing regulator supplies. Now that the
binding supports them, add all the power rail supplies. Most of them
are fed from a system-wide semi-regulated power rail. A couple LDOs
are fed from the PMIC's own buck regulator outputs.
