This changeset adds support for the AD9467 LVDS High-Speed ADC. In order to support it, support for an FPGA ADI AXI ADC is added in this set. This uses the current support for IIO buffer DMAEngine. Changelog v4 -> v5: * update drivers/iio/adc/Kconfig note about module name; omitted during first rename - 'module will be called axi-adc.' -> 'module will be called adi-axi-adc.' Changelog v3 -> v4: * addressed Rob's dt-remarks - change 'adi-axi-adc-client' prop to 'adi,adc-dev' Changelog v2 -> v3: * addressed compiler warning Changelog v1 -> v2: * first series was added a bit hastily * addressed 'make dt_binding_check' complaints; seems I missed a few when running the check; * added missing patches to include/linux/fpga/adi-axi-common.h - 'include: fpga: adi-axi-common.h: fixup whitespace tab -> space' - 'include: fpga: adi-axi-common.h: add version helper macros' * patch 'iio: buffer-dmaengine: add dev-managed calls for buffer alloc/free' - remove copy+pasted comment for 'devm_iio_dmaengine_buffer_alloc()' - removed devm_iio_dmaengine_buffer_free() ; hopefully it might never be needed - fix-up alignment for devm_iio_dmaengine_buffer_alloc() in header * patch 'iio: adc: adi-axi-adc: add support for AXI ADC IP core' - renamed axi-adc.c -> adi-axi-adc.c & Kconfig symbol - prefix all axi_adc -> adi_axi_adc - removed switch statement in axi_adc_read_raw() & axi_adc_write_raw() - remove axi_adc_chan_spec ; replaced with iio_chan_spec directly ; will think of a simpler solution for extra chan params - removed left-over 'struct axi_adc_cleanup_data' - moved 'devm_add_action_or_reset()' call right after 'adi_axi_adc_attach_client()' - switched to using 'devm_platform_ioremap_resource()' * patch 'iio: adc: ad9467: add support AD9467 ADC' - renamed ADI_ADC reg prefixes to AN877_ADC - dropped 'info_mask_separate' field in AD9467_CHAN - will be re-added later when driver gets more features; was left-over from the initial ref driver - remove .shift = 0, in AD9467_CHAN - renamed 'sample-clock' -> 'adc-clock' - direct returns in ad9467_read_raw() & ad9467_write_raw() & ad9467_setup() switch statements - removed blank line after devm_axi_adc_conv_register() - removed ad9467_id & reworked to use ad9467_of_match Alexandru Ardelean (6): include: fpga: adi-axi-common.h: fixup whitespace tab -> space include: fpga: adi-axi-common.h: add version helper macros iio: buffer-dmaengine: use %zu specifier for sprintf(align) iio: buffer-dmaengine: add dev-managed calls for buffer alloc dt-bindings: iio: adc: add bindings doc for AXI ADC driver dt-bindings: iio: adc: add bindings doc for AD9467 ADC Michael Hennerich (2): iio: adc: adi-axi-adc: add support for AXI ADC IP core iio: adc: ad9467: add support AD9467 ADC .../bindings/iio/adc/adi,ad9467.yaml | 65 ++ .../bindings/iio/adc/adi,axi-adc.yaml | 63 ++ drivers/iio/adc/Kconfig | 35 ++ drivers/iio/adc/Makefile | 2 + drivers/iio/adc/ad9467.c | 432 +++++++++++++ drivers/iio/adc/adi-axi-adc.c | 566 ++++++++++++++++++ .../buffer/industrialio-buffer-dmaengine.c | 41 +- include/linux/fpga/adi-axi-common.h | 6 +- include/linux/iio/adc/adi-axi-adc.h | 63 ++ include/linux/iio/buffer-dmaengine.h | 3 + 10 files changed, 1274 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/iio/adc/adi,ad9467.yaml create mode 100644 Documentation/devicetree/bindings/iio/adc/adi,axi-adc.yaml create mode 100644 drivers/iio/adc/ad9467.c create mode 100644 drivers/iio/adc/adi-axi-adc.c create mode 100644 include/linux/iio/adc/adi-axi-adc.h -- 2.20.1
