/*

* - The V3 firmware is for r8a7796 (with good performance).

* - The V2 firmware can be used on both r8a7795 (es1.x) and r8a7796.

* - The V2 firmware is possible to use on R-Car Gen2. However, the V2 causes

*   performance degradation. So, this driver continues to use the V1 if R-Car

*   Gen2.
