iio: dac: ad5446: Add IDs of compatible Texas Instruments chips
The Texas Instruments DAC081S101, DAC101S101 and DAC121S101 have the exact same pinout, programming interface and power-down modes as the AD5300, AD5310 and AD5320, respectively, and their datasheets declare them "a direct replacement" for the Analog Devices chips. This may not be immediately obvious to a casual observer, so add them to the supported modalias strings. Datasheets: http://www.ti.com/lit/ds/symlink/dac081s101.pdf http://www.ti.com/lit/ds/symlink/dac101s101.pdf http://www.ti.com/lit/ds/symlink/dac121s101.pdf http://www.analog.com/media/en/technical-documentation/data-sheets/AD5300.pdf http://www.analog.com/media/en/technical-documentation/data-sheets/AD5310.pdf http://www.analog.com/media/en/technical-documentation/data-sheets/AD5320.pdf Signed-off-by: Lukas Wunner <lukas@wunner.de> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
