I immediately thought "yeah, this is it", but had to do some resarch where my assumption comes from. I found it in older H2 datasheets (v0.9). Here in 56.1: "Automatic transmission for PMIC control: The IIC3 module of the R-Car H2 and M2 supports automatic data transmission under PMIC control (DVFS)." Or table 56.8: "Registers of IIC Command for Automatic Transmission Mode (IIC3 only) [R-CarH2, M2, and V2H]" This all is a strong indication for IIC3 only. Which SoCs that have is still confusing. Table 56.8 mentions V2H but 56.1 doesn't. Then again, I could imagine that V2H has it but simply DVFS is not advertised for V2H. And in the later documents, DVFS advertisement was removed for H2 and M2 as well. (PS: sorry for replying to the "wrong" thread, I accidently deleted the "correct" one)
