Subject: [PATCH v1 2/3] arm64: dts: amlogic: a1: introduce cpu temperature sensor
Date: Thu, 28 Mar 2024 16:44:38 +0300	[thread overview]
Message-ID: <20240328134459.18446-3-ddrokosov@salutedevices.com> (raw)
In-Reply-To: <20240328134459.18446-1-ddrokosov@salutedevices.com>

The A1 SoC family has only one thermal sensor for CPU temperature
measurement. It is required to set the TS clock rate to 500kHz to make
it workable.
