[PATCH v5 0/2] iio: adc: Add Maxim MAX11100 driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Hello everyone,
  hopefully we have reached last iteration on this simple driver.

After having clarified the read_raw() measure unit question, I'm now sending
out v5 addressing Jonathan's comment on having spi destination aligned to
their own cache lines to support DMA-capable SPI controllers.

Also, I added indio_dev->name attribute, as suggested by Lars-Peter even if
the same value can be retrieved from of_node/name.


v1 -> v2:
    - incorporated pmeerw's review comments
    - retrieve vref from dts and use that to convert read_raw result
      to mV
    - add device tree bindings documentation

v2 -> v3:
    - add _SCALE bit of read_raw function and change _RAW bit accordingly
    - call regulator_get_voltage when accessing the _SCALE part of read_raw
      and not during probe
    - add back remove function as regulator has to be disabled when detaching
      the module. Do not use devm_ version of iio_register/unregister functions
      anymore but do unregister in the remove.
    - remove mutex as access to SPI bus is protected by SPI core. Thanks marex

v3 -> v4:
    - split device tree binding documentation and actual ADC driver
    - add "reg" to the list of required properties and use a better
      namimg for the adc device node in bindings documentation as suggested
      by Geert.

v4 -> v5:
    - make spi_read() destination buffer cacheline aligned
    - add indio_dev->name attribute.
