Subject[PATCH v1 01/10] arm/arm64: dts: msm8974/msm8916: thermal: Split address space into two
Date
We've earlier added support to split the register address space into TM
and SROT regions.

Split up the regmap address space into two for the remaining platforms that
have a similar register layout and make corresponding changes to the
get_temp_common() function used by these platforms.

Since tsens-common.c/init_common() currently only registers one address
space, the order is important (TM before SROT). This is OK since the code
doesn't really use the SROT functionality yet.
