drivers: add Atmel SAM PWM driver This patch adds basic support for the PWM devices available on the Atmel SAM family. Beside enabling the driver, everything is selected through the device tree, including enabling the PWM0 and PWM1 devices. Thus CONFIG_PWM_0 and CONFIG_PWM_1 are ignored.

yaml: Remove redundant document separators YAML document separators are needed e.g. when doing $ cat doc1.yaml doc2.yaml | <parser> For the bindings, we never parse concatenated documents. Assume we don't for any other .yaml files either. Having document separators in e.g. base.yaml makes !include a bit confusing, since the !included files are merged and not separate documents (the merging is done in Python code though, so it makes no difference for behavior). The replacement was done with $ git ls-files '*.yaml' | \ xargs sed -i -e '${/\s*\.\.\.\s*/d;}' -e 's/^\s*---\s*$//' First pattern removes ... at the end of files, second pattern clears a line with a lone --- on it. Some redundant blank lines at the end of files were cleared with $ git ls-files '*.yaml' | xargs sed -i '${/^\s*$/d}' This is more about making sure people can understand why every part of a binding is there than about removing some text.

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.

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: use const to validate #<FOO>-cells In most cases #<FOO>-cells should be a constant. For example in spi controller #address-cells should be 1, and #size-cells should be 0. Use the const attribute to specify such single known values. Add const value to missing bindings which have cells. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

"#pwm-cells":
const: 2
scripts: dts: Generalize '#cells' to allow multiple sources Implement a nice generalization suggested by Bobby Noelte. Instead of having a generic #cells key in bindings, have source-specific *-cells keys. Some examples: interrupt-cells: - irq - priority - flags gpio-cells: - pin - flags pwm-cells: - channel - period This makes bindings a bit easier to read, and allows a node to be a controller for many different 'phandle-array' properties. The prefix before *-cells is derived from the property name, meaning there's no fixed set of *-cells keys. This is possible because of the earlier 'phandle-array' generalization. The older #cells key is supported for backwards compatibility, but generates a deprecation warning. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>
