1Analog devices AS3645A device tree bindings 2 3The AS3645A flash LED controller can drive two LEDs, one high current 4flash LED and one indicator LED. The high current flash LED can be 5used in torch mode as well. 6 7Ranges below noted as [a, b] are closed ranges between a and b, i.e. a 8and b are included in the range. 9 10Please also see common.txt in the same directory. 11 12 13Required properties 14=================== 15 16compatible : Must be "ams,as3645a". 17reg : The I2C address of the device.
