dts: bindings: Remove 'title:' and put all info. into 'description:' Add any useful information from 'title:' to the 'description:' strings (e.g. explanations of acronyms), and remove 'title:' as well as any copy-pasted "this binding gives a ..." boilerplate. Also clean some description strings up a bit. Some other things could probably be cleaned up (replacing 'GPIO node' with 'GPIO controller' on controllers for consistency, for example), but I kept things close to the original to avoid accidentally messing up.

description: Atmel SAM0 multi-protocol (UART, SPI, I2C) SERCOM unit
spi: sam0: use Device Tree for configuration. Switch the SoC device tree to define a single entry per SERCOM instead of one per mode. Define a Device Tree binding for the SAM0 SPI and use it instead of Kconfig for enabling / disabaling instances Switch the Arduino Zero, Adafruit Feather M0 Basic Proto, and Trinket M0 to use the new defintion. Add the APA102 LED that's on the Trinket as a test. Signed-off-by: Michael Hope <mlhx@google.com> Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

scripts: dts: Simplify and improve 'compatible' matching Instead of properties: compatible: constraint: "foo" , just have compatible: "foo" at the top level of the binding. For backwards compatibility, the old 'properties: compatible: ...' form is still accepted for now, and is treated the same as a single-element 'compatible:'. The old syntax was inspired by dt-schema (though it isn't dt-schema-compatible), which is in turn a thin wrapper around json-schema (the idea is to transform .dts files into YAML and then verify them). Maybe the idea was to gradually switch the syntax over to dt-schema and then be able to use unmodified dt-schema bindings, but dt-schema is really a different kind of tool (a completely standalone linter), and works very differently from our stuff (see schemas/dt-core.yaml in the dt-schema repo to get an idea of just how differently). Better to keep it simple. This commit also piggybacks some clarifications to the binding template re. '#cells:'. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

dts/bindings: Convert bindings to new include syntax Convert from: inherits: !include spi-device.yaml to: include: spi-device.yaml Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

include: base.yaml
dts/bindings: Move common properties into a base.yaml Move common properties like 'compatible', 'reg', 'reg-names', 'interrupts', 'interrupt-names', and 'label' into one common base.yaml that all the other yaml's can inherit from. This removes both duplication and inconsistent definition. The device specific yamls just need to say if a property is 'required' or not. NOTE: due to some generation conflicts we did not covert 'soc-nv-flash.yaml' to use base.yaml. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

dts: atmel: sam0: Add initial clock devicetree support Add support for the GCLK, MCLK, and PM clock controllers. Add bindings and devicetree nodes associated with these clock controllers.
