2024-02-17dt-bindings: iio: afe: voltage-divider: Add io-channel-cellsNaresh Solanki1-0/+11
Enable the voltage divider to both receive and provide measurement services by adding #io-channel-cells. This is especially valuable in scenarios where an ADC has an analog frontend, like a voltage divider, and obtaining its raw value isn't interesting. It is desired to get the real voltage before the voltage divider.

2022-02-28dt-bindings: iio: afe: add bindings for temperature transducersLiam Beguin1-0/+114
An ADC is often used to measure other quantities indirectly. This binding describe one case, the measurement of a temperature through a temperature transducer (either voltage or current).

2021-05-17dt-bindings: iio: afe: current-sense-shunt: add io-channel-cellsKrzysztof Kozlowski1-0/+4
The current-sense-shunt is an IIO provider thus can be referenced by IIO consumers (via "io-channels" property in consumer device node). Such provider is required to describe number of cells used in phandle lookup with "io-channel-cells" property. This also fixes dtbs_check warnings like: arch/arm/boot/dts/s5pv210-fascinate4g.dt.yaml: current-sense-shunt: '#io-channel-cells' does not match any of the regexes: 'pinctrl-[0-9]+' Fixes: ce66e52b6c16 ("dt-bindings:iio:afe:current-sense-shunt: txt to yaml conversion.")

Simple binding so straight forward conversion, though did require adding a separate binding document for the max1027 to reflect its abilities to provide channels to consumers.

Note this includes a fix in the example where we had *-mul instead of *-mult.
