Subject: [PATCH v2 0/5] Add driver for LTC2664 and LTC2672
Date: Thu, 23 May 2024 11:19:04 +0800

Generalize the ABI documentation for DAC. The ABI defined for toggle mode
channels:

LTC2664:
  * out_voltageY_toggle_en
  * out_voltageY_raw0
  * out_voltageY_raw1
  * out_voltageY_symbol

LTC2672:
  * out_currentY_toggle_en
  * out_currentY_raw0
  * out_currentY_raw1
  * out_currentY_symbol

Default channels won't have any of the above ABIs. A channel is toggle capable
if the devicetree 'adi,toggle-mode' flag is set.

changes in v2:

ltc2664:
  * Updated struct ltc2664_chip_info to include device-specific data for scale,
    offset, measurement type, internal vref, manual span support, and rfsadj
    support.
  * Added a read-only extended info attribute powerdown_mode to indicate the
    state that the DAC output enters when the device is powered down.
  * Refactored code for setting the span into separate function and directly
    returning the span.
  * Adjusted memory allocation for st->iio_channels to include null terminator.
  * Spaces have been added after { and before }. Each pair of values is now
    placed on a separate line.

ABI:
  * Generalized the ABI documentation for DAC.
  * Added DAC 42kohm_to_gnd powerdown mode.

Bindings:
  * Created separate bindings for ltc2664 and ltc2672.
  * Added v-pos-supply and v-neg-supply regulator properties.
  * Renamed vref-supply to ref-supply based on the datasheet.
  * Added io-channels property and specifying the pin for multiplexer output.
  * Added vdd0-vdd4 supply properties for ltc2672, although they are not
    currently supported in the driver.
  * Changed clr-gpios description based on the datasheet.
  * Used 4 spaces for example indentation.
