rj10接口4个脚定义和控制
RJ10-4pin: 输出电源控制 LOW=0v,HIGH=5v
rj10-vcc-pin = <&gpio4 RK_PC3 GPIO_ACTIVE_HIGH>;
RJ10-2,3脚 的电压等级：HIGH=5V
rj10txrx5v-pin = <&gpio4 RK_PD0 GPIO_ACTIVE_HIGH>;
RJ-2,3 脚 的电压等级：HIGH=12V
rj10txrx12v-pin = <&gpio2 RK_PD2 GPIO_ACTIVE_HIGH>;
综上三个引脚功能： RJ10的1脚为GND，2、3脚为TX、RX，4脚为电源，由rj10-vcc-pin控制。 而通信接口电平由rj10txrx5v-pin和rj10txrx12v-pin组合决定是5V还是12V。
USB接口定义和控制
板上的USB用5V开关电源变换器使能总控制：
hub-vcc-en-pin = <&gpio0 RK_PC5 GPIO_ACTIVE_HIGH>;
gpiochip0 line 21
USB3.0端口HOST输出电源控制：
device-host-pin = <&gpio3 RK_PC4 GPIO_ACTIVE_HIGH>;
gpiochip3 line 20
USB2.0端口输出电源控制
左边1#
hub-vcc-pin = <&gpio4 RK_PC6 GPIO_ACTIVE_HIGH>;
gpiochip4 line 22
右边2#
host-b-vcc-pin = = <&gpio4 RK_PC5 GPIO_ACTIVE_HIGH>;
gpiochip4 line 21
若要开机即可完成开启usb电源与端口，可在启动服务中打开引脚
nano /etc/custom_service/start_service.sh
加入以下语句即可
# For swan1-w28 board USB power and switch contrl
# USB 5V Power buick ON
gpioset 0 21=1
# USB3.0 Port ON
gpioset 3 20=1
# USB2.0 Port ON
gpioset 4 21=1
gpioset 4 22=1
rj11插座6个脚定义及控制：
ctl-gpio1 = <&gpio4 RK_PC2 GPIO_ACTIVE_HIGH>;
ctl-gpio2 = <&gpio4 RK_PD2 GPIO_ACTIVE_HIGH>;
P1，P6=GND，P2,P5=ctl-gpio1漏极OC驱动输出，P3=固定12V，P4=ctl-gpio2输出HIGH=3V，
