dt-bindings: iio: afe: add bindings for temperature transducers

2022-02-28T10:22:25Z

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).

dt-bindings: iio: afe: current-sense-shunt: add io-channel-cells

2021-05-17T12:54:24Z

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.")

dt-bindings:iio:afe:voltage-divider: txt to yaml conversion

2020-12-03T19:40:21Z

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.

Very simple binding. As such straight forward conversion. Signed-off-by: Jonathan Cameron Reviewed-by: Rob Herring Cc: Peter Rosin Link: https://lore.kernel.org/r/20201031181242.742301-7-jic23@kernel.org

Note this includes a fix in the example where we had *-mul instead of *-mult. The binding doc and driver agree that it should be *-mult Signed-off-by: Jonathan Cameron Reviewed-by: Rob Herring Cc: Peter Rosin Link: https://lore.kernel.org/r/20201031181242.742301-6-jic23@kernel.org

Similar to current sense shunts, but an amplifier enables the use of a smaller sense resistance. Signed-off-by: Peter Rosin Reviewed-by: Rob Herring Signed-off-by: Jonathan Cameron
