From 4c33cef58965eb655a0ac8e243aa323581ec025f Mon Sep 17 00:00:00 2001 From: Oleksij Rempel Date: Mon, 27 Oct 2025 13:44:15 +0100 Subject: [PATCH] regulator: pca9450: link regulator inputs to supply groups Add supply_name entries for all PCA9450 regulators to describe their respective input pin groups (INB13, INB26, INB45, INL1). This links each buck and LDO to the upstream supply that powers its input group. On some systems, power faults such as undervoltage are detected before the PMIC itself. Defining supply relationships allows the regulator framework to propagate such events properly through the dependency chain.
