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.

title: PWM Base Structure
description: >
This binding gives the base structures for all PWM devices
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>

yaml: fix properties syntax to 'mapping' instead of 'series' According to yaml syntaxic rules, 'properties' described in dts bindings yaml files could be seen as 'mapping'(key/value couple), instead of 'series' (list of single elements). yaml 'mappings' will then be converted by yaml python library as python 'dict' which will ease treatment (instead of current list as were before this commit). Same treatment is applied to 'inherits'. script extract_dts_inlcude is updated to take change of yaml_list structre into account. This allows some code simplification. Largest impact is yaml_collapse function which works now allow complete overload method on all the attributes of a yaml nodes. Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>
