Subject: [PATCH V5 1/4] dt-bindings: Add Broadcom AVS RO thermal
Date: Mon, 13 Jan 2020 19:56:15 +0100 [thread overview]
Message-ID: <1578941778-23321-2-git-send-email-stefan.wahren@i2se.com> (raw)
In-Reply-To: <1578941778-23321-1-git-send-email-stefan.wahren@i2se.com>
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.
