跟别的版本有点不一样。

sim1 是 贴片卡
sim3 是 外置卡槽

debian中

		sim_sel {
			label = "sim:sel";
			gpios = <0x49 0x01 0x00>;
			default-state = "on";
		};

		sim_en {
			label = "sim:en";
			gpios = <0x49 0x14 0x00>;
			default-state = "off";
		};

		sim_sel2 {
			label = "sim:sel2";
			gpios = <0x49 0x16 0x00>;
			default-state = "off";
		};

		sim_en2 {
			label = "sim:en2";
			gpios = <0x49 0x17 0x00>;
			default-state = "off";
		};

sim_sel2 对应于 原 sim1
sim_en2  对应于 原 sim2
sim_sel  对应于 原 sim3 （也就外置卡槽)
sim_en   对应于 原 hotdet

android中
