+Subject: [PATCH] dt-bindings: Add Broadcom AVS RO thermal
+
+Commit ee31ff373da6602e7a4e60fe11322b41ac38eb22 upstream.
+
+Since the BCM2711 doesn't have a AVS TMON block, the thermal information
+must be retrieved from the AVS ring oscillator block. This block is part
+of the AVS monitor which contains a bunch of raw sensors.
