[PATCH v6 0/3] iio: Add Cosmic Circuits ADC support

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

 




This series add the support for an ADC IP block from Cosmic Circuits.
The patchset is based on v3.19-rc3.

Rob/Mark: Jonathan has asked for an ack of the devicetree binding. Do you
think you can take a look to that?

Thanks a lot!

Changes from v5:

  * Fixed CC10001_ADC_CH_MASK macro definition, to separate the channel
    number from the channel map, as noted by Hartmut.
  * Return the real error code in devm_regulator_get failure.

Changes from v4:

  * Added a compile-time dependency on REGULATOR and HAVE_CLK.
  * Replaced the silly XOR operation for a proper mask out of the
    available channels.

Changes from v3:

  * Fixed a few style nitpicks as per Hartmut's feedback.
  * Used GENMASK() to build the channel mask, which fixes a very nasty
    bug. Also found by Hartmut.

Changes from v2:

  * Changed a devicetree property from adc-available-channels to
    adc-reserved-channels, so it can be made optional.
  * Renamed the driver from cc_10001_xxx to cc10001_xxx so it's consistent
    with the rest of the kernel style.
  * Some more minor cosmetic fixes.

Changes from v1:

  * Removed unneeded header includes.
  * Changed all the names and macros prefix: s/CC_10001_/CC10001_.
  * Used .update_scan_mode callback to preallocate the buffer.
  * Used indio_dev for the struct iio_dev.
  * Only read the regulator voltage when needed.
  * Fixed probe() error handling.
  * Used for_each_set_bit() instead of open-coding it.
  * Name the power-down register as _POWER_UP, to make the code
    less silly.
  * Error out when no valid sample can be read (i.e. when end-of-conversion
    poll times out).
  * ... plus some assorted code cleaning based on the feedback.
