Subject: [PATCH v4 6/7] thermal: sun8i: add support for H616 THS controller
Date: Fri,  9 Feb 2024 14:42:20 +0000	[thread overview]
Message-ID: <20240209144221.3602382-7-andre.przywara@arm.com> (raw)
In-Reply-To: <20240209144221.3602382-1-andre.przywara@arm.com>

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

Add support for the thermal sensor found in H616 SoCs, is the same as
the H6 thermal sensor controller, but with four sensors.
Also the registers readings are wrong, unless a bit in the first SYS_CFG
register cleared, so set exercise the SRAM regmap to take care of that.
