Subject: [PATCH v3 0/2] iio: add unit converter
Date: Tue, 10 Apr 2018 17:28:00 +0200 [thread overview]
Message-ID: <20180410152802.30958-1-peda@axentia.se> (raw)
Hi!
This driver implements support for voltage dividers and current
sense shunts. It's pretty generic and should be easily adaptable
to other linear scaling purposes.
Cheers,
Peter
Changes since v2: https://lkml.org/lkml/2018/4/3/461
- Rename from current-sence-circuit to current-sense-shunt (this
should also fix all the typing problems I had with curciut).
- Describe the shunt resistance directly (instead of indirectly
in the form of a quotient).
- Add a ->props() op to struct unit_converter_cfg to enable simple
separation of properties for different converters.
- Shuffle the code around to minimize forward declarations.
- Drop the unused indio member from struct unit_converter.
- Drop error report on iio driver registration failure.
Changes since v1: https://lkml.org/lkml/2018/3/19/801
- Put the driver in the new afe category (Analog Front Ends) and do not
move the iio-mux driver.
- Do not refer to the source channel as "parent", use "source" instead.
- Have the DT compatible drive the target unit, instead of relying on a
"type" DT-property for that.
- In the DT bindings, use an unnamed source channel.
- Do not set up writes to _RAW (sorry Phil) as I don't need it and have
not tested it. It's easy to add back if needed.
- Fail if the source channel does not support _RAW or _SCALE.
- Fix various spelling issues.
- Fix various code style issues.
