Subject: [PATCH v4 7/7] arm64: dts: allwinner: h616: Add thermal sensor and zones
Date: Fri,  9 Feb 2024 14:42:21 +0000	[thread overview]
Message-ID: <20240209144221.3602382-8-andre.przywara@arm.com> (raw)
In-Reply-To: <20240209144221.3602382-1-andre.przywara@arm.com>

From: Martin Botka <martin.botka@somainline.org>

There are four thermal sensors:
- CPU
- GPU
- VE
- DRAM

Add the thermal sensor configuration and the thermal zones.
