af6aca65 - iio: dac: Support ROHM BD79703 DAC

Thu, 19 Dec 2024 11:39:37 +0000

iio: dac: Support ROHM BD79703 DACThe ROHM BD79703 is a 6 channel digital to analog converter.Based on the data-sheet examples the hardware would support setting theDAC word without changing the actual output. The data-sheet is not toospecific on how the enabling the output of new voltage set by DACshould be done - hence this is not implemented by the driver.The BD79703 would also support two specific "PULL_DOWN" modes. Thesearen't currently supported by the driver either.Add a very basic support for controlling the channel outputs one-by-one.Signed-off-by: Matti Vaittinen Link: https://patch.msgid.link/bc77d7b979ca28408a216f597082fcd94ec63be7.1734608215.git.mazziesaccount@gmail.comSigned-off-by: Jonathan Cameron List of files: /linux-6.15/drivers/iio/dac/Kconfig

iio: dac: ad3552r: add high-speed platform driverAdd High Speed ad3552r platform driver.The ad3552r DAC is controlled by a custom (fpga-based) DAC IPthrough the current AXI backend, or similar alternative IIO backend.Compared to the existing driver (ad3552r.c), that is a simple SPIdriver, this driver is coupled with a DAC IIO backend that finallycontrols the ad3552r by a fpga-based "QSPI+DDR" interface, to reachmaximum transfer rate of 33MUPS using dma stream capabilities.All commands involving QSPI bus read/write are delegated to the backendthrough the provided APIs for bus read/write.Reviewed-by: Nuno Sa Signed-off-by: Angelo Dureghello Reviewed-by: David Lechner Link: https://patch.msgid.link/20241028-wip-bl-ad3552r-axi-v0-iio-testing-v9-7-f6960b4f9719@kernel-space.orgSigned-off-by: Jonathan Cameron List of files: /linux-6.15/drivers/iio/dac/Kconfig
