2021-07-20dt-bindings: i2c: at91: fix example for scl-gpiosNicolas Ferre1-1/+1
[ Upstream commit 92e669017ff1616ba7d8ba3c65f5193bc2a7acbe ] The SCL gpio pin used by I2C bus for recovery needs to be configured as open drain, so fix the binding example accordingly. In relation with fix c5a283802573 ("ARM: dts: at91: Configure I2C SCL gpio as open drain").

But most of them are all over the place. - removal of the efm32, sirf, u300, and zte zx bus drivers because of platform removal.

2021-01-30dt-bindings: Cleanup standard unit propertiesRob Herring2-5/+0
Properties with standard unit suffixes already have a type and don't need type definitions. They also default to a single entry, so 'maxItems: 1' can be dropped. adi,ad5758 is an oddball which defined an enum of arrays. While a valid schema, it is simpler as a whole to only define scalar constraints.

2020-12-14dt-bindings: i2c: dw: cancel mandatory requirements for "#address-cells" and ↵Zhen Lei1-8/+0
"#size-cells" The "#address-cells" and "#size-cells" are required only when the I2C controller has subnodes. However, some I2C controllers defined in "arch/arm64/boot/dts/amd/" and "arch/arm64/boot/dts/hisilicon/" directories do not have child nodes. So they don't need these two properties and don't write them explicitly. Therefore, setting properties "#address-cells" and "#size-cells" as "required" in this yaml file causes the following warnings: /root/linux-next/arch/arm64/boot/dts/hisilicon/hi6220-hikey.dt.yaml: \ i2c@f7100000: '#address-cells' is a required property /root/linux-next/arch/arm64/boot/dts/hisilicon/hi6220-hikey.dt.yaml: \ i2c@f7100000: '#size-cells' is a required property Signed-off-by: Zhen Lei <thunder.leizhen@huawei.com> Link: https://lore.kernel.org/r/20201214124347.2120-2-thunder.leizhen@huawei.com Signed-off-by: Rob Herring <robh@kernel.org>

'unevaluatedProperties' is appropriate when including another schema (via '$ref') and all possible properties and/or child nodes are not explicitly listed in the schema with the '$ref'.

2020-08-14dt-bindings: Whitespace clean-ups in schema filesRob Herring2-18/+18
Clean-up incorrect indentation, extra spaces, long lines, 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 (which I plan to integrate into the checks).

The I2C GPIO bus recovery properties consist of two GPIOS and one extra pinctrl state ("gpio" or "recovery"). "recovery" pinctrl state is considered deprecated and "gpio" should be used instead. Not all are mandatory for recovery.

2020-07-17dt-bindings: i2c-gpio: Use 'deprecated' keyword on deprecated propertiesRob Herring1-4/+4
The i2c-gpio binding is the only case of 'not: true' being used for a deprecated property. Update it to use the json-schema 2019.09 'deprecated' keyword instead. Define the type too in order to keep the meta-schema happy. This will disable warnings for these properties until the dtschema tools are updated to handle 'deprecated', but they are only used in a few at91 dts files.

A conversion of the i2c-pxa binding to DT schema format using json-schema. This also cleans ups some errors in the binding: The compatible string description suggested that "mmp" in "mrvl,mmp-twsi" is to be substituted with a processor model, which wouldn't be a right thing to do and indeed nobody seems to have been doing that. There also was "Recommended properties" section that included optional as well as mandatory properties. Missing mandatory properties were added to the example.
