1GPIO-controlled Multiplexers (MUX) A/D Converter bindings 2 3Required properties: 4- compatible: should be "gpio-muxadc" or others like below 5 - "sgm3699": for a quad, bidirectional, single-pole/double-throw (SPDT) CMOS analog switch. 6 - "sgm48752": for a dual, bidirectional, double-pole/double-throw (DPDT) CMOS analog switch. 7- io-channels: Channel node of the parent channel that has multiplexed input. 8- switch-gpios: Digital control pins to connect the parent adc channel(saradc) to the input adc channel(muxadc). 9- labels: The string list for each muxadc channel that should be placed in order. 10 11Example: 12 muxadc { 13 compatible = "sgm48752"; 14 io-channels = <&saradc 4>, <&saradc 5>; 15 switch-gpios = <&gpio1 RK_PA0 GPIO_ACTIVE_HIGH>, 16 <&gpio1 RK_PA1 GPIO_ACTIVE_HIGH>; 17 labels = "wheel_vpropi_r_adc", "wheel_vpropi_l_adc", 18 "fan_opa_adc", "mid_opa_adc", 19 "pump_opa_adc", "side_opa_adc", 20 "dc24vdet_adc", "collision_det_adc_lidar"; 21 pinctrl-names = "default"; 22 pinctrl-0 = <&switch_gpios>; 23 status = "okay"; 24 }; 25
