Rob, I was thinking in sending a different patch for the io-channels fix but then I changed my mind and included it in this series as it is then easier to apply the io-backends patch on top of it. If you prefer for me to send that patch alone, I'll do so. Keeping the block diagram so we don't have to follow links to check one of the typical setups. ------------------------------------------------------- ------------------ | ----------- ------------ ------- FPGA | | ADC |------------------------| | AXI ADC |---------| DMA CORE |------| RAM | | | (Frontend/IIO) | Serial Data (eg: LVDS) | |(backend)|---------| |------| | | | |------------------------| ----------- ------------ ------- | ------------------ ------------------------------------------------------- --- Nuno Sa (8): of: property: fix typo in io-channels dt-bindings: adc: ad9467: add new io-backend property dt-bindings: adc: axi-adc: update bindings for backend framework driver: core: allow modifying device_links flags iio: buffer-dmaengine: export buffer alloc and free functions iio: add the IIO backend framework iio: adc: ad9467: convert to backend framework iio: adc: adi-axi-adc: move to backend framework Olivier Moysan (1): of: property: add device link support for io-backends .../devicetree/bindings/iio/adc/adi,ad9467.yaml | 4 + .../devicetree/bindings/iio/adc/adi,axi-adc.yaml | 8 +- MAINTAINERS | 8 + drivers/base/core.c | 14 +- drivers/iio/Kconfig | 9 + drivers/iio/Makefile | 1 + drivers/iio/adc/Kconfig | 4 +- drivers/iio/adc/ad9467.c | 268 +++++++++----- drivers/iio/adc/adi-axi-adc.c | 383 +++++-------------- drivers/iio/buffer/industrialio-buffer-dmaengine.c | 8 +- drivers/iio/industrialio-backend.c | 412 +++++++++++++++++++++ drivers/of/property.c | 4 +- include/linux/iio/adc/adi-axi-adc.h | 68 ---- include/linux/iio/backend.h | 72 ++++ include/linux/iio/buffer-dmaengine.h | 3 + 15 files changed, 805 insertions(+), 461 deletions(-) --- base-commit: 824adc9cc314be065db726e30fae876c87660775 change-id: 20231219-iio-backend-a3dc1a6a7a58 -- Thanks! - Nuno Sá
