    Subject[PATCH v6 0/8] iio: adi-axi-adc,ad9647: Add support for AD9467 ADC
    Date
    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 v5 -> v6
    * fix URLs; got changed during rename
    https://wiki.analog.com/resources/fpga/docs/adi_axi_adc_ip ->
    https://wiki.analog.com/resources/fpga/docs/axi_adc_ip
    - noticed while working on the AXI DAC driver

    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
