What: /sys/kernel/debug/iio/iio:deviceX/calibration_table_dump KernelVersion: 6.11 Contact: linux-iio@vger.kernel.org Description: This dumps the calibration table that was filled during the digital interface tuning process.

What: /sys/kernel/debug/iio/iio:deviceX/in_voltage_test_mode_available KernelVersion: 6.11 Contact: linux-iio@vger.kernel.org Description: List all the available test tones: - off - midscale_short - pos_fullscale - neg_fullscale - checkerboard - prbs23 - prbs9 - one_zero_toggle - user - bit_toggle - sync - one_bit_high - mixed_bit_frequency - ramp

	Note that depending on the actual device being used, some of the
	above might not be available (and they won't be listed when
	reading the file).

What: /sys/kernel/debug/iio/iio:deviceX/in_voltageY_test_mode KernelVersion: 6.11 Contact: linux-iio@vger.kernel.org Description: Writing to this file will initiate one of available test tone on channel Y. Reading it, shows which test is running. In cases where an IIO backend is available and supports the test tone, additional information about the data correctness is given.
