0001 Analog devices AS3645A device tree bindings
0002
0003 The AS3645A flash LED controller can drive two LEDs, one high current
0004 flash LED and one indicator LED. The high current flash LED can be
0005 used in torch mode as well.
0006
0007 Ranges below noted as [a, b] are closed ranges between a and b, i.e. a
0008 and b are included in the range.
