1Cortina Systems Gemini pin controller 2 3This pin controller is found in the Cortina Systems Gemini SoC family, 4see further arm/gemini.txt. It is a purely group-based multiplexing pin 5controller. 6 7The pin controller node must be a subnode of the system controller node. 8 9Required properties: 10- compatible: "cortina,gemini-pinctrl" 11 12Subnodes of the pin controller contain pin control multiplexing set-up 13and pin configuration of individual pins. 14 15Please refer to pinctrl-bindings.txt for generic pin multiplexing nodes 16and generic pin config nodes. 17 18Supported configurations: 19- skew-delay is supported on the Ethernet pins 20 21Example: 22 23 24syscon { 25 compatible = "cortina,gemini-syscon"; 26 ... 27 pinctrl { 28 compatible = "cortina,gemini-pinctrl"; 29 pinctrl-names = "default"; 30 pinctrl-0 = <&dram_default_pins>, <&system_default_pins>, 31 <&vcontrol_default_pins>; 32 33 dram_default_pins: pinctrl-dram { 34 mux { 35 function = "dram"; 36 groups = "dramgrp"; 37 }; 38 }; 39 rtc_default_pins: pinctrl-rtc { 40 mux { 41 function = "rtc"; 42 groups = "rtcgrp"; 43 }; 44 }; 45 power_default_pins: pinctrl-power { 46 mux { 47 function = "power"; 48 groups = "powergrp"; 49 }; 50 }; 51 system_default_pins: pinctrl-system { 52 mux { 53 function = "system"; 54 groups = "systemgrp"; 55 }; 56 }; 57 (...) 58 uart_default_pins: pinctrl-uart { 59 mux { 60 function = "uart"; 61 groups = "uartrxtxgrp"; 62 }; 63 }; 64 }; 65}; 66
