2024-02-15dt-bindings: w1: UART 1-Wire busChristoph Winklhofer1-0/+59
Add device tree binding for UART 1-Wire bus. Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Christoph Winklhofer <cj.winklhofer@gmail.com> Link: https://lore.kernel.org/r/20240209-w1-uart-v6-2-3e753c149196@gmail.com Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
2023-11-16dt-bindings: w1: Add AMD AXI w1 host and MAINTAINERS entryKris Chaplin1-0/+44
Add YAML DT schema for the AMD AXI w1 host IP. This hardware guarantees protocol timing for driving off-board devices such as thermal sensors, proms, etc using the 1wire protocol. The IP has a register to detect hardware version and so the binding does not have an explicit version number. Add MAINTAINERS entry for DT schema.

2023-04-20dt-bindings: w1: Add DS2482/DS2484 I2C to 1-W bridgesStefan Wahren1-0/+44
This adds a dedicated devicetree binding for the Maxim DS2482/DS2484 I2C to 1-W bridges, which can be extended later for further features (e.g. sleep mode control GPIO). Since one wire is a bus, child nodes needs to be allowed here.

2022-08-25dt-bindings: Remove 'Device Tree Bindings' from end of title:Andrew Lunn1-1/+1
As indicated in link: https://lore.kernel.org/all/20220822204945.GA808626-robh@kernel.org/ DT schema files should not have 'Device Tree Binding' as part of there title: line. Remove this in most .yaml files, so hopefully preventing developers copying it into new .yaml files, and being asked to remove it.

2021-10-04dt-bindings: w1-gpio: Drop redundant 'maxItems'Rob Herring1-1/+0
Drop another redundant maxItems that snuck into w1-gpio binding. If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems.

2021-09-13dt-bindings: w1: Convert 1-Wire GPIO binding to a schemaMaxime Ripard2-27/+44
Bitbanged 1-Wire buses are supported by Linux thanks to their device tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that driver over to a YAML schema.

2020-10-27dt-bindings: More whitespace clean-ups in schema filesRob Herring1-4/+4
Clean-up incorrect indentation, extra spaces, and missing EOF newline in schema files. Most of the clean-ups are for list indentation which should always be 2 spaces more than the preceding keyword. Found with yamllint (now integrated into the checks).

This patch adds a generic w1 bindings document that describes how w1 slave deviceses are grouped under master nodes. It also augments the existing w1-gpio.txt document a bit.

2017-09-05dt-bindings: Remove "status" from examplesRob Herring1-1/+0
Pretty much any node can have a status property, so it doesn't need to be in examples. Converted with the following command and removed examples with SoC and board specific splits: git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d' Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Rob Herring <robh@kernel.org>
