The Cortina Gemini pin controller uses the standard pin control
bindings for muxing functions with groups so these bindings
should be entirely uncontroversial.

+Cortina Systems Gemini pin controller
+
+This pin controller is found in the Cortina Systems Gemini SoC family,
+see further arm/gemini.txt. It is a purely group-based multiplexing pin
+controller.
+
+Required properties:
+- compatible: "cortina,gemini-pinctrl"
+- regmap: phandle to the system controller node
+
+Subnodes of the pin controller contain pin control multiplexing set-up.
+Please refer to pinctrl-bindings.txt for generic pin multiplexing nodes.
+
+Example:
+
+pinctrl {
+ compatible = "cortina,gemini-pinctrl";
+ regmap = <&syscon>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&dram_default_pins>, <&system_default_pins>,
+ <&vcontrol_default_pins>;
+
+ dram_default_pins: pinctrl-dram {
+ mux {
+ function = "dram";
+ groups = "dramgrp";
+ };
+ };
+ rtc_default_pins: pinctrl-rtc {
+ mux {
+ function = "rtc";
+ groups = "rtcgrp";
+ };
+ };
+ power_default_pins: pinctrl-power {
+ mux {
+ function = "power";
+ groups = "powergrp";
+ };
+ };
+ system_default_pins: pinctrl-system {
+ mux {
+ function = "system";
+ groups = "systemgrp";
+ };
+ };
+ (...)
+ uart_default_pins: pinctrl-uart {
+ mux {
+ function = "uart";
+ groups = "uartrxtxgrp";
+ };
+ };
+};
