[PATCH v2 6/6] iio: dac: ad5686: extend device support with new parts
From: Rodrigo Alencar via B4 Relay
Date: Fri Jul 24 2026 - 08:05:03 EST
From: Rodrigo Alencar <rodrigo.alencar@xxxxxxxxxx>
Add support for AD5313R, AD5317R, AD5674, AD5679, AD5687, AD5687R, AD5689,
AD5689R to the AD5686 SPI driver. Also adding support for AD5316R, AD5675,
AD5697R to the AD5696 I2C driver. This includes the creation of seven chip
info struct instances and reuse of existing ones.
Signed-off-by: Rodrigo Alencar <rodrigo.alencar@xxxxxxxxxx>
