   4 Subject: [PATCH] thermal/drivers/sun8i: Add support for H616 THS controller
   5
   6 Add support for the thermal sensor found in H616 SoCs, is the same as
   7 the H6 thermal sensor controller, but with four sensors.
   8 Also the registers readings are wrong, unless a bit in the first SYS_CFG
   9 register cleared, so set exercise the SRAM regmap to take care of that.
