[PATCH v1] arm64: dts: qcom: monaco-evk: Add firmware-name to QUPv3 nodes
From: Viken Dadhaniya
Date: Thu Sep 25 2025 - 00:26:26 EST
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.
