+maintainers:

+
+description:
+  The Renesas RZ/T2H and RZ/N2H SoCs feature a combined Pin and GPIO controller.
+  Pin multiplexing and GPIO configuration are performed on a per-pin basis.
+  Each port supports up to 8 pins, each configurable for either GPIO (port mode)
+  or alternate function mode. Each pin supports function mode values ranging from
+  0x0 to 0x2A, allowing selection from up to 43 different functions.
