Subject[PATCH v13 0/8] iio: adi-axi-adc,ad9647: Add support for AD9467 ADC
Date
Changelog v12 -> v13:
* patch 'iio: adc: adi-axi-adc: add support for AXI ADC IP core'
- removed padding around 'adi_axi_adc_conv_register()'

Changelog v11 -> v12:
* used DocLink: and Datasheet: instead of Link: tag
* patch 'iio: adc: adi-axi-adc: add support for AXI ADC IP core'
- removed NULL checks from places where the code does pointer
arithmethic
- removed comma from NULL terminators in list
- changed to use of_device_get_match_data() to get driver data
- moved device table data to bottom of driver
* patch 'iio: adc: ad9467: add support AD9467 ADC'
- moved device table data to bottom of driver

Changelog v10 -> v11:
* added 'Reviewed-by: Rob Herring <robh@kernel.org>' tag to DT bindings patches
* patch 'dt-bindings: iio: adc: add bindings doc for AXI ADC driver'
removed 'maxItems' from dma-names property
* sent from an @analog.com server; author was showing as @gmail.com on
V9 & V10

Changelog v9 -> v10:
* patch 'iio: adc: adi-axi-adc: add support for AXI ADC IP core'
- removed IQ correction logic; the AD9467 ADC driver has only 1 channel,
so it can't have I & Q; also the IQ correction assumes that all
even channels are Q and all odd channels are I, which is true for
current ADI-AXI ADC IP cores, but shouldn't be an assumption designed
in the driver; the IQ correction stuff will be re-added later,
and will try to use the IIO_MOD_I & IIO_MOD_Q modifiers

Changelog v8 -> v9:
* adding more Analog people to the list; predominantly HDL people; this
should help me sync people about the details of regs/reg-names
* added 'Acked-by: Moritz Fischer <mdf@kernel.org>' tag to fpga patches
- we can always re-update these patches if something else is decided about
the location of the 'adi-axi-common.h' header; I'm not insisting about
where to put it; I'm open to other proposals
* patch 'iio: adc: adi-axi-adc: add support for AXI ADC IP core'
- prefixed regs ADI_AXI_ ; I tried ADI_AXI_ADC_, but that seemed to make
them too long
- dropped unused regs; will add them as stuff gets added in the upstream
driver; in the meantime, reg-names can be reworked
- dropped generic LOWERXY_SET/GET macros
- update reg-names a bit; will update them in the docs and HDL
- order in adi_axi_adc_conv_unregister() should now be symmetrically
oppposite now to the register function
- implemented 'is_visible()' callback to adi_axi_adc_attributes[] so that
attrs can be made invisible to userspace if needed;
- 'indio_dev->name = "adi-axi-adc";'
- added kernel doc-string for @reg_access
* patch 'iio: adc: ad9467: add support AD9467 ADC'
- ad9467_spi_read() split in 2 buffers; tbuf & rbuf
- removed 'if (chan->extend_name)' test ; left-over from initial driver
- removed 'if (!st->clk)' check; driver will fail probe without a clock
- removed 'if (!spi->dev.of_node)' in probe; shouldn't be needed
- using 'of_device_get_match_data()' in probe to get data; moved chip
info table entry as data on the of_device_id table

Changelog v7 -> v8:
* in 'iio: adc: adi-axi-adc: add support for AXI ADC IP core'
- updated register definitions and bits to newer format/docs; the ref driver wasn't really up-to-date
-- prefixed bit names with reg-name to avoid bit definition colisions; that makes some macros longer, but at least the format is consistent
- using dev_name(&pdev->dev) for indio_dev->name
- moved reset to own axi_adc_reset() function; may be re-used later
- some re-formatting/alignment changes
- address ENOSYS checkpatch complaint; changed with EOPNOTSUPP

Changelog v6 -> v7:
* Fixed dt-schema build for adi,axi-adc.yaml based on Rob's suggestion
- added '$ref: /schemas/types.yaml#/definitions/phandle' to 'adi,adc-dev'
- dropped 'maxItems' from 'adi,adc-dev'

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
