Uh, I'm sorry, I'm new to the Linux upstreaming game. I'm used to
using code review tools like Gerrit, which help with that.

Changes from "PATCH v2 1/2" to "PATCH v4 1/2" (v3 was sent with a
typo, so please ignore v3):
- Removed extra layer "temperature-sensors" as discussed.
- Renamed "sensor" to "input" as discussed.
- Renamed "mode" to "sensor-type" to indicate temperature or voltage.
- Added "temperature-mode" to indicate "thermistor" or "thermal-diode".
- Removed description attributes from "sensor-type" and didn't add for
"temperature-mode", since they would have just repeated the names of
the properties.
- Numbered sensors 0 (LTD) and 1..3 (RTD1..3).

Some notes:
- While 1..3 are "natural numberings", there's no equivalent for "0"
in the datasheet - the name "0" is arbitrary. An alternative would be
to name this sensor "ltd" instead of "input", since it's not
configurable (beyond disabling it).
- I wasn't sure what the correct way is to enforce a match from
"input@X" to "reg = <X>", so I listed the inputs individually.
Technically RTD1 and RTD2 could be done as "patternProperties", if we
could enforce the match between @X and reg.

I hope I included all the various comments and discussion points both
from PATCH v2 and from the "tmp421" thread [1]. Please let me know if
I missed anything.

Does this proposal match the general thinking and goals for
dt-bindings for hwmon devices?

Thanks
Oskar.
