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 v3:
ltc2664:
* Added span sanity check for no match.
* Initialized the variable 'span' to fix build warning.
* Added Reported-by and Closes by tag.
ABI:
* Modified descriptions to make it more generalize.
* Removed MAINTAINERS file entry.
Bindings:
* Changed clr-gpios to reset-gpios.
* Added output range and reset code description for 'adi,manual-span-operation-config'
property in ltc2664 binding.
* Removed the $ref for 'adi,output-range-microamp' due to dt-schema warning
in ltc2672 binding. Added Reported-by and Closes by tag.
* Modified io-channels description and added maxItems constraint.
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.
