iio_dev_attr_in_voltage1_scale_available
iio_dev_attr_in_voltage2_scale_available
iio_dev_attr_in_voltage3_scale_available
iio_dev_attr_in_voltage4_scale_available
iio_dev_attr_in_voltage5_scale_available
iio_dev_attr_in_voltage6_scale_available
iio_dev_attr_in_voltage7_scale_available
iio_dev_attr_in_voltage10_scale_available
iio_dev_attr_in_voltage11_scale_available
iio_dev_attr_in_voltage12_scale_available
iio_dev_attr_in_voltage13_scale_available
