From 30b5167b808c5a7eb8559bbd296fce14cb62e58d Mon Sep 17 00:00:00 2001 From: Viken Dadhaniya Date: Thu, 25 Sep 2025 09:56:05 +0530 Subject: [PATCH] arm64: dts: qcom: monaco-evk: Add firmware-name to QUPv3 nodes Traditionally, firmware loading for Serial Engines (SE) in the QUP hardware of Qualcomm SoCs has been managed by TrustZone (TZ). While this approach ensures secure SE assignment and access control, it limits flexibility for developers who need to enable various protocols on different SEs. Add the firmware-name property to QUPv3 nodes in the device tree to enable firmware loading from the Linux environment. Handle SE assignments and access control permissions directly within Linux, removing the dependency on TrustZone.
