[PATCH RFC v2 2/5] arm64: dts: qcom: nord: Add gpr node
From: Shawn Guo
Date: Wed Oct 21 2026 - 03:38:27 EST
From: Mohammad Rafi Shaik <mohammad.rafi.shaik@xxxxxxxxxxxxxxxx>
Add the GPR (Generic Packet Router) node to the nord SoC DTSI along
with the APM (Audio Process Manager) and PRM (Proxy Resource Manager)
audio services. These nodes are required by the Q6APM audio stack to
route audio packets between the application processor and the DSP.
