[PATCH 1/2] dt-bindings: thermal: amlogic: Add A9 thermal bindings
From: Xianwei Zhao via B4 Relay
Date: Thu Jul 30 2026 - 04:54:06 EST
From: Xianwei Zhao <xianwei.zhao@xxxxxxxxxxx>
Document the thermal controller compatibles for the Amlogic A9 SoC.
Describe the required "core" and "plck" clocks, add the optional
"amlogic,hw-reset-temp" property, and update the schema constraints for
A9-specific thermal controllers.
