According to Section 76.1.3.5 ("PHY Register Configuration"), the
USB3.0 PHY register block is only present on R-Car H3, M3-W, M3-W+,
and M3-N, but not on R-Car E3?

Likewise, Figure 76.1 ("Clock Distribution [R-Car H3, H3-N, M3-W,
M3-W+, M3-N]") does not cover R-Car E3. Unfortunately there is no
separate picture for R-Car E3.

Gr{oetje,eeting}s,
