1*4882a593Smuzhiyun* Texas Instruments OPT3001 Ambient Light Sensor 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunThe driver supports interrupt-driven and interrupt-less operation, depending 4*4882a593Smuzhiyunon whether an interrupt property has been populated into the DT. Note that 5*4882a593Smuzhiyunthe optional generation of IIO events on rising/falling light threshold changes 6*4882a593Smuzhiyunrequires the use of interrupts. Without interrupts, only the simple reading 7*4882a593Smuzhiyunof the current light value is supported through the IIO API. 8*4882a593Smuzhiyun 9*4882a593Smuzhiyunhttps://www.ti.com/product/opt3001 10*4882a593Smuzhiyun 11*4882a593SmuzhiyunRequired properties: 12*4882a593Smuzhiyun - compatible: should be "ti,opt3001" 13*4882a593Smuzhiyun - reg: the I2C address of the sensor 14*4882a593Smuzhiyun 15*4882a593SmuzhiyunOptional properties: 16*4882a593Smuzhiyun - interrupts: interrupt mapping for GPIO IRQ (configure for falling edge) 17*4882a593Smuzhiyun 18*4882a593SmuzhiyunExample: 19*4882a593Smuzhiyun 20*4882a593Smuzhiyunopt3001@44 { 21*4882a593Smuzhiyun compatible = "ti,opt3001"; 22*4882a593Smuzhiyun reg = <0x44>; 23*4882a593Smuzhiyun interrupt-parent = <&gpio1>; 24*4882a593Smuzhiyun interrupts = <28 IRQ_TYPE_EDGE_FALLING>; 25*4882a593Smuzhiyun}; 26
