Subject: arm64: dts: qcom: hamoa-iot-som: Add firmware-name to QUPv3 nodes
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cb7db0f4010f8b7392b007b803b1b3c718d7baeb;p=thirdparty%2Fkernel%2Fstable.git

arm64: dts: qcom: hamoa-iot-som: 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.
