Subject: [PATCH 3/4] iio: ABI: add ABI file for the LTC2672 DAC
Date: Fri, 12 Apr 2024 11:21:01 +0800 [thread overview]
Message-ID: <20240412032102.136071-4-kimseer.paller@analog.com> (raw)
In-Reply-To: <20240412032102.136071-1-kimseer.paller@analog.com>
Define the sysfs interface for toggle capable channels.
Toggle enabled channels will have:
* out_currentY_toggle_en
* out_currentY_raw0
* out_currentY_raw1
* out_currentY_symbol
The common interface present in all channels is:
* out_currentY_raw (not present in toggle enabled channels)
* out_currentY_raw_available
* out_currentY_powerdown
* out_currentY_scale
* out_currentY_offset

+Description:
+ Toggle enable. Write 1 to enable toggle or 0 to disable it. This is
+ useful when one wants to change the DAC output codes. The way it should
+ be done is:
+
+ - disable toggle operation;
+ - change out_currentY_raw0 and out_currentY_raw1;
+ - enable toggle operation.

+Contact: linux-iio@vger.kernel.org
+Description:
+ It has the same meaning as out_currentY_raw. This attribute is
+ specific to toggle enabled channels and refers to the DAC output
+ code in INPUT_A (_raw0) and INPUT_B (_raw1). The same scale and offset
+ as in out_currentY_raw applies.

+Description:
+ Performs a SW toggle. This attribute is specific to toggle
+ enabled channels and allows to toggle between out_currentY_raw0
+ and out_currentY_raw1 through software. Writing 0 will select
+ out_currentY_raw0 while 1 selects out_currentY_raw1.
