This patch and [12/13] are adding SoC-specific compatible name.
Of course we don't know future request,
and, adding SoC-specific compatible name for
fallbacking is nice safety for us.
So, I don't have strong objection about it.
But, thermal driver side do nothing for each
SoC-specific compatible name at this point.
This means
-> There is no trouble in driver/SoC
-> Add new (and not used) compatible name
-> Nothing happen in driver/SoC
My questions are...
1) How to verify this patch ?
2) Do we need to update example SoC "specific name" list in rcar-thermal.txt.
Few example codes are very enough ?
