From 5af8a9e8430ce62a4e12e58c687c43bae0d5863f Mon Sep 17 00:00:00 2001 From: Viken Dadhaniya Date: Tue, 23 Sep 2025 21:41:07 +0530 Subject: [PATCH] arm64: dts: qcom: qcs6490-rb3gen2: 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.
