The bots have been poking them since Wednesday without any issues. There are a few fixes in the ad7091r5 driver as part of rework to enable the ad7091r8 parts that are included at start of that series. Includes pre-work for major changes to the DMA buffers that should land in 6.9 and will greatly improve performance and flexibility for high performance devices by enabling DMABUF based zero copy transfers when we don't need to bounce the data via user space. New device support ------------------ adi,ad7091r8 - Major refactor of existing adi,ad7091r5 driver to separate out useful shared library code that can be used by I2C and SPI parts. - Use that library from a new driver supporting the AD7091R-2, AD7091R-4 and AD7091R-8 12-Bit SPI ADCs. - Series includes some late breaking fixes for the ad7091r5. microchip,mcp4821 - New driver for MCP4801, MCP4802, MCP4811, MCP4812, MCP4821 and MCP4822 I2C single / dual channel DACs. Cleanup ------- buffers: - Use IIO_SEPARATE in place of some hard-coded 0 values. dma-buffers: - Simplify things to not use an outgoing queue given it only ever has up to two elements and we only need to track which is first. - Split the iio_dma_buffer_fileio_free() function up to make it easier to read and enable reuse in a series lining up for 6.9 iio.h - Drop some stale documentation of struct fields that don't exist. ---------------------------------------------------------------- Alexandru Ardelean (1): iio: buffer-dma: split iio_dma_buffer_fileio_free() function Anshul Dalal (2): dt-bindings: iio: dac: add MCP4821 iio: dac: driver for MCP4821 Christophe JAILLET (1): iio: buffer: Use IIO_SEPARATE instead of a hard-coded 0 Marcelo Schmitt (11): iio: adc: ad7091r: Allow users to configure device events iio: adc: ad7091r: Enable internal vref if external vref is not supplied iio: adc: ad7091r: Move generic AD7091R code to base driver and header file iio: adc: ad7091r: Move chip init data to container struct iio: adc: ad7091r: Remove unneeded probe parameters iio: adc: ad7091r: Set device mode through chip_info callback iio: adc: ad7091r: Add chip_info callback to get conversion result channel iio: adc: Split AD7091R-5 config symbol dt-bindings: iio: Add AD7091R-8 iio: adc: Add support for AD7091R-8 MAINTAINERS: Add MAINTAINERS entry for AD7091R Paul Cercueil (1): iio: buffer-dma: Get rid of outgoing queue Randy Dunlap (1): iio: linux/iio.h: fix Excess kernel-doc description warning .../devicetree/bindings/iio/adc/adi,ad7091r5.yaml | 82 ++++++- .../bindings/iio/dac/microchip,mcp4821.yaml | 86 +++++++ MAINTAINERS | 15 ++ drivers/iio/adc/Kconfig | 16 ++ drivers/iio/adc/Makefile | 4 +- drivers/iio/adc/ad7091r-base.c | 269 +++++++++++++------- drivers/iio/adc/ad7091r-base.h | 83 ++++++- drivers/iio/adc/ad7091r5.c | 120 +++++---- drivers/iio/adc/ad7091r8.c | 272 +++++++++++++++++++++ drivers/iio/buffer/industrialio-buffer-dma.c | 87 ++++--- drivers/iio/dac/Kconfig | 10 + drivers/iio/dac/Makefile | 1 + drivers/iio/dac/mcp4821.c | 236 ++++++++++++++++++ drivers/iio/industrialio-buffer.c | 6 +- include/linux/iio/buffer-dma.h | 7 +- include/linux/iio/iio.h | 6 - 16 files changed, 1107 insertions(+), 193 deletions(-) create mode 100644 Documentation/devicetree/bindings/iio/dac/microchip,mcp4821.yaml create mode 100644 drivers/iio/adc/ad7091r8.c create mode 100644 drivers/iio/dac/mcp4821.c
