The description below is already in use for rk3308.dtsi, but was somehow never added to a document, so add "rockchip,rk3308-saradc", "rockchip,rk3399-saradc" for saradc nodes on a rk3308 platform to rockchip-saradc.yaml. Signed-off-by:

Current dts files with 'saradc' nodes are manually verified. In order to automate this process rockchip-saradc.txt has to be converted to yaml. Signed-off-by:

The IIO DMA buffer is a DMA buffer implementation. As such it should include buffer_impl.h rather than buffer.h. The include to buffer.h in buffer-dma.h should be buffer_impl.h so it has access to the struct iio_buffer definition. The code currently only works because all places that use buffer-dma.h include buffer_impl.h before it. The include to buffer.h in industrialio-buffer-dma.c can be removed since those file does not reference any of buffer consumer functions. Signed-off-by:

Michael Hennerich authored
The AD9467 is a 16-bit, monolithic, IF sampling analog-to-digital converter (ADC). It is optimized for high performanceover wide bandwidths and ease of use. The product operates at a 250 MSPS conversion rate and is designed for wireless receivers, instrumentation, and test equipment that require a high dynamic range. The ADC requires 1.8 V and 3.3 V power supplies and a low voltage differential input clock for full performance operation. No external reference or driver components are required for many applications. Data outputs are LVDS compatible (ANSI-644 compatible) and include the means to reduce the overall current needed for short trace distances. Since the chip can operate at such high sample-rates (much higher than classical interfaces), it requires that a DMA controller be used to interface directly to the chip and push data into memory. Typically, the AXI ADC IP core is used to interface with it. Datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/AD9467.pdfSigned-off-by:

This change adds the bindings documentation for the AXI ADC driver. Reviewed-by:
-
Michael Hennerich authored
This change adds support for the Analog Devices Generic AXI ADC IP core. The IP core is used for interfacing with analog-to-digital (ADC) converters that require either a high-speed serial interface (JESD204B/C) or a source synchronous parallel interface (LVDS/CMOS). Usually, some other interface type (i.e SPI) is used as a control interface for the actual ADC, while the IP core (controlled via this driver), will interface to the data-lines of the ADC and handle the streaming of data into memory via DMA. Because of this, the AXI ADC driver needs the other SPI-ADC driver to register with it. The SPI-ADC needs to be register via the SPI framework, while the AXI ADC registers as a platform driver. The two cannot be ordered in a hierarchy as both drivers have their own registers, and trying to organize this [in a hierarchy becomes] problematic when trying to map memory/registers. There are some modes where the AXI ADC can operate as standalone ADC, but those will be implemented at a later point in time.

Currently, when using a 'iio_dmaengine_buffer_alloc()', an matching call to 'iio_dmaengine_buffer_free()' must be made. With this change, this can be avoided by using 'devm_iio_dmaengine_buffer_alloc()'. The buffer will get free'd via the device's devres handling. Signed-off-by:

The 'size_t' type behaves differently on 64-bit architectures, and causes compiler a warning of the sort "format '%u' expects argument of type 'unsigned int', but argument 3 has type 'size_t {aka long unsigned int}'". This change adds the correct specifier for the 'align' field. Fixes: 4538c185 ("iio: buffer-dmaengine: Report buffer length requirements") Reported-by:kbuild test robot <lkp@intel.com> Signed-off-by:

This seems like a left-over from a7348347 ("staging:iio: Add polling of events on the ring access chrdev."). Then it was moved into the sca3000 driver around 9dd4694d ("iio: staging: sca3000: hide stufftoread logic"), and that one seemed to be the only user of this. Then it eventually was no longer used after 152a6a88 ("staging:iio:accel:sca3000 move to hybrid hard / soft buffer design.") Signed-off-by:
