iio: dac: add mcf54415 DAC

2026-07-01T17:58:22+00:00

Add basic version of mcf54415 DAC driver. DAC is embedded in the SoC and DAC configuration registers are mapped in the internal IO address space. The DAC accepts a 12-bit digital signal and creates a monotonic 12-bit analog output varying from DAC_VREFL to DAC_VREFH. The DAC module consists of a conversion unit, an output amplifier, and the associated digital control blocks. Default register values for DAC_VREFL and DAC_VREFH are respectively 0 and 0xfff, left untouched in this initial version. This initial version of the driver is minimalistic, "output raw" only, to be extended in the future. DMA and external sync are disabled, default mode is high speed, default format is right-justified 12-bit on 16-bit word.

iio: dac: adding support for Microchip MCP47FEB02

2025-12-31T17:59:18+00:00

This is the iio driver for Microchip MCP47F(E/V)B(0/1/2)1, MCP47F(E/V)B(0/1/2)2, MCP47F(E/V)B(0/1/2)4 and MCP47F(E/V)B(0/1/2)8 series of buffered voltage output Digital-to-Analog Converters with nonvolatile or volatile memory and an I2C Interface. The families support up to 8 output channels. The devices can be 8-bit, 10-bit and 12-bit. Signed-off-by: Ariana Lazar Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron

iio: dac: ad5446: Separate I2C/SPI into different drivers

2025-11-09T16:15:13+00:00

Properly separate the I2C and SPI drivers into two different drivers living in their own source file (as usual). So that no need for the hacky ifdefery. Signed-off-by: Nuno Sá Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron

iio: dac: ad3530r: Add driver for AD3530R and AD3531R

2025-05-21T13:20:29+00:00

The AD3530/AD3530R (8-channel) and AD3531/AD3531R (4-channel) are low-power, 16-bit, buffered voltage output DACs with software- programmable gain controls, providing full-scale output spans of 2.5V or 5V for reference voltages of 2.5V. These devices operate from a single 2.7V to 5.5V supply and are guaranteed monotonic by design. The "R" variants include a 2.5V, 5ppm/°C internal reference, which is disabled by default. Support for monitoring internal die temperature, output voltages, and current of a selected channel via the MUXOUT pin using an external ADC is currently not implemented.

iio: dac: Support ROHM BD79703 DAC

2024-12-28T14:28:14+00:00

The ROHM BD79703 is a 6 channel digital to analog converter. Based on the data-sheet examples the hardware would support setting the DAC word without changing the actual output. The data-sheet is not too specific on how the enabling the output of new voltage set by DAC should be done - hence this is not implemented by the driver. The BD79703 would also support two specific "PULL_DOWN" modes. These aren't currently supported by the driver either. Add a very basic support for controlling the channel outputs one-by-one.

iio: dac: ad3552r: add high-speed platform driver

2024-11-03T20:33:32+00:00

Add High Speed ad3552r platform driver. The ad3552r DAC is controlled by a custom (fpga-based) DAC IP through the current AXI backend, or similar alternative IIO backend. Compared to the existing driver (ad3552r.c), that is a simple SPI driver, this driver is coupled with a DAC IIO backend that finally controls the ad3552r by a fpga-based "QSPI+DDR" interface, to reach maximum transfer rate of 33MUPS using dma stream capabilities. All commands involving QSPI bus read/write are delegated to the backend through the provided APIs for bus read/write.
