For SoC identification, it is a different SoC altogether, so we need to use a dedicated compatible. For SYSC, it lacks the A2VC power area compared to the RZ/G2M v1.X so we cannot use family compatible. Similarly for clock, it lacks some modules such as the FCPCI, so we need to use a dedicated compatible. R-CAR M3-W (r8a77960) is similar to RZ/G2M (r8a774a1) and R-CAR M3-W+ (r8a77961) is similar to RZ/G2M v3.0(r8a774a3). So, I referred R-CAR M3-W+ bindings and made similar changes for this SoC. I will update the commit messages for SoC, SYSC and clk to reflect this. Thank you, Oliver
