iio: add MCP4728 I2C DAC driver

2023-08-05T18:29:39+00:00

MCP4728 is a 12-bit quad channel DAC with I2C interface. support for: * per-channel gain * per-channel power state * per-channel power down mode control * per-channel vref selection internal/vdd * store current state to on-chip EEPROM Signed-off-by: Andrea Collamati Link: https://lore.kernel.org/r/a0933003ed3c855f9d80d6ce0a40add2b6f0ba36.1691066050.git.andrea.collamati@gmail.com Signed-off-by: Jonathan Cameron

iio: dac: cio-dac: Migrate to the regmap API

2023-03-18T16:42:52+00:00

The regmap API supports IO port accessors so we can take advantage of regmap abstractions rather than handling access to the device registers directly in the driver. Includes trivial header inclusion tidy up.

iio: dac: add support for max5522

2023-01-21T17:58:59+00:00

Add initial support for DAC max5522. Tested writing DAC A and B with some values, from 0 to 1023, measured output voltages, driver works properly. Additions for max5523/24/25 will follow.

iio: dac: ad5686: Add support for AD5337

2022-12-28T17:19:45+00:00

AD5337 belongs to the same family as the AD5338. The difference is that the AD5337 has 8-bit precision instead of 10-bit. Add support for the AD5337 chip in the driver.

iio: dac: ti-dac5571: add support for ti,dac121c081

2022-06-11T13:35:27+00:00

It fits right in as a single 12-bit DAC. Reviewed-by: Sean Nyekjaer Signed-off-by: Peter Rosin Link: https://lore.kernel.org/r/a09a49a5-3d01-21f7-02ed-b191d70e7609@axentia.se Signed-off-by: Jonathan Cameron
