-  controller.
+  The Renesas SoCs of the RZ/{G2L,V2L} alike series feature a combined Pin and
+  GPIO controller.
   Pin multiplexing and GPIO configuration is performed on a per-pin basis.
   Each port features up to 8 pins, each of them configurable for GPIO function
   (port mode) or in alternate function mode.
