2022-08-19dt-bindings: iio: potentiometer: use spi-peripheral-props.yamlKrzysztof Kozlowski2-8/+10
Instead of listing directly properties typical for SPI peripherals, reference the spi-peripheral-props.yaml schema. This allows using all properties typical for SPI-connected devices, even these which device bindings author did not tried yet. Remove the spi-* properties which now come via spi-peripheral-props.yaml schema, except for the cases when device schema adds some constraints like maximum frequency. While changing additionalProperties->unevaluatedProperties, put it in typical place, just before example DTS.

2021-01-11dt-bindings: Add missing array size constraintsRob Herring1-0/+1
DT properties which can have multiple entries need to specify what the entries are and define how many entries there can be. In the case of only a single entry, just 'maxItems: 1' is sufficient. Add the missing entry constraints. These were found with a modified meta-schema. Unfortunately, there are a few cases where the size constraints are not defined such as common bindings, so the meta-schema can't be part of the normal checks.

2020-12-03dt-bindings:iio:potentiometer: give microchip,mcp4531 its own bindingJonathan Cameron1-0/+116
We use this part in an example for the envelope detector. That showed that we need to allow for the #io-channel-cells property which trivial-devices.yaml does not. It doesn't make sense to add that property to trivial-devices as it only applies for those devices that can provide some sort of DAC or ADC service to another device driver. Hence solution will be to pull some IIO devices out to have their own file on a case by case basis.

2020-11-22dt-bindings:iio:potentiometer:microchip,mcp41010 txt to yaml conversionJonathan Cameron2-28/+48
A simple binding that I almost just move to trivial devices. The small amount of additional documentation and relatively large number of compatible entries convinced me to suggest we keep this one separately documented.

2020-11-22dt-bindings:iio:potentiometer:microchip,mcp4131 txt to yaml conversionJonathan Cameron2-84/+103
This binding is very simple, but I think the very large number of compatible values make it unsuitable for moving to trivial-devices.yaml. Main change in the conversion was reordering the compatible list to numerical order.

Simple SPI binding that doesn't need a separate file.

2020-07-13Replace HTTP links with HTTPS ones: Documentation/devicetree/bindings/iioAlexander A. Klimov1-1/+1
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.
