+title: RaspberryPi RP1 GPIO/Pinconf/Pinmux Controller submodule
+
+maintainers:
+  - Andrea della Porta <andrea.porta@suse.com>
+
+description:
+  The RP1 chipset is a Multi Function Device containing, among other sub-peripherals,
+  a gpio/pinconf/mux controller whose 54 pins are grouped into 3 banks. It works also
+  as an interrupt controller for those gpios.
+
+  Each pin configuration node lists the pin(s) to which it applies, and one or
+  more of the mux function to select on those pin(s), and their configuration.
+  The pin configuration and multiplexing supports the generic bindings.
+  For details on each properties (including the meaning of "pin configuration node"),
+  you can refer to ./pinctrl-bindings.txt.
