[参考译文] PROCESSOR-SDK-AM62X：GPIO 配置

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1516352/processor-sdk-am62x-gpio-configuration

工具/软件：

我正在处理 GPIO 配置、其中添加了两个引脚的配置、如下所示：

/ {
	aliases {
		gpio = &main_pmx0;
	};

	sensor {
		compatible = "gpio-keys";
		pinctrl-names = "default";
		pinctrl-0 = <&gpio_pins_default>;

		close {
			label = "Close";
			gpios = <&main_gpio1 10 GPIO_ACTIVE_LOW>;
			// linux,code = <KEY_ENTER>;
		};

		open {
			label = "Open";
			gpios = <&main_gpio1 9 GPIO_ACTIVE_LOW>;
			// linux,code = <KEY_ENTER>;
		};
	};
};

&main_pmx0 {
	gpio_pins_default: gpio-default-pins {
		bootph-all;
		pinctrl-single,pins = <
			AM62X_IOPAD(0x1A0, PIN_INPUT, 7) /* (E18) */
			AM62X_IOPAD(0x19C, PIN_INPUT, 7) /* (B18) */
		>;
	};
};

但无法获取并设置 GPIO、我需要有关如何操作的帮助。
