The reason we also have the SoC-specific values is that we are not
100% sure the thermal IP cores in the Renesas R-Car Gen1 and R-Car Gen2
series are really identical.
Currently the driver treats all of them the same, but if we ever discover
a difference, and the driver needs to start distinguishing among different
versions, we will need to have the SoC-specific values in the DTSes to
do so.
I hope this explains our rationale.
