[PATCH 0/2] platform: arm64: Add Radxa SVC GLINK support

From: Xilin Wu

Date: Mon Aug 31 2026 - 13:25:35 EST


Hi,

Add support for the RADXA_SVC_ADSP_APPS firmware service found on
supported Radxa boards using Qualcomm SoCs.

The service provides fan control and optional temperature, voltage,
current, and power sensor readings. These functions are exposed through
the standard hwmon interface.

The firmware SET_PROFILE operation only selects a fan curve and does not
change the overall system performance profile. The quiet and performance
curves are therefore represented as automatic pwm1_enable modes instead of
using the platform_profile framework.

The first patch adds the rpmsg client and fan control support. The second
patch adds discovery and registration of the optional firmware sensors.

This series is tested on Radxa Dragon Q8B (SC8280XP).
