Add property for the edge type of the hardware trigger pin ADTRG Signed-off-by: Eugen Hristev <redacted> Acked-by: Rob Herring <robh@kernel.org> Acked-by: Ludovic Desroches <ludovic.desroches@microchip.com>
Applied to the togreg branch of iio.git and pushed out as testing for the autobuilders to play with it. Thanks, Jonathan
