Dither capable channels will have the extended interface: * out_voltageY_dither_en * out_voltageY_dither_raw * out_voltageY_dither_offset * out_voltageY_dither_raw_available * out_voltageY_dither_frequency * out_voltageY_dither_frequency_available * out_voltageY_dither_phase * out_voltageY_dither_phase_available Toggle enabled channels will have: * out_voltageY_toggle_en * out_voltageY_raw0 * out_voltageY_raw1 * out_voltageY_symbol The common interface present in all channels is: * out_voltageY_raw (not present in toggle enabled channels) * out_voltageY_raw_available * out_voltageY_powerdown * out_voltageY_scale * out_voltageY_offset * out_voltageY_calibbias * out_voltageY_calibscale Signed-off-by: Nuno Sá Link: https://lore.kernel.org/r/20220225130129.69-3-nuno.sa@analog.com Signed-off-by: Jonathan Cameron --- MAINTAINERS | 1 + 1 file changed, 1 insertion(+) (limited to 'MAINTAINERS') diff --git a/MAINTAINERS b/MAINTAINERS index 7f2e55a5ed2f..29f4b6d39f3a 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -11322,6 +11322,7 @@ M: Nuno Sá L: linux-iio@vger.kernel.org S: Supported W: http://ez.analog.com/community/linux-device-drivers +F: Documentation/ABI/testing/sysfs-bus-iio-dac-ltc2688 F: drivers/iio/dac/ltc2688.c LTC2947 HARDWARE MONITOR DRIVER -- cgit v1.2.3
