- Subject: [PATCH] thermal/drivers/sun8i: Add support for H616 THS controller
- 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.
