Add support to enable the HDL IP core internal ramp generator,
actually managed by the adi-axi-dac backend.
It works this way:
/sys/bus/iio/devices/iio:device0# echo 1 > buffer0/out_voltage0_en
/sys/bus/iio/devices/iio:device0# echo 1 > buffer0/out_voltage1_en
/sys/bus/iio/devices/iio:device0# echo 1 > buffer0/enable
Activating ramp generator:
/sys/kernel/debug/iio/iio:device0# echo -n backend-ramp-generator > data_source
Deactivating:
/sys/kernel/debug/iio/iio:device0# echo -n iio-buffer > data_source
