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: edtlib: Sanity-check the final merged binding only Sanity-checking each !included file separately was inherited from the old scripts. It makes it messy to check that combinations of fields make sense, e.g. to check 'const:' or 'default:' against 'type:', since those fields might come from different files (this is handy, since it makes sense to just add/change a 'const:' value, for example). Drop the requirement that each !included file is a complete binding in itself, and treat them as binding fragments instead. Only check the final merged binding. This also means that !included files no longer need to have a 'description:' or 'title:' (those have always been unused for !included files), so remove those, and add comments that explain what the fragments are for instead. That should demystify bindings a bit. Also fix the descriptions of i2c.yaml, i2s.yaml, spi.yaml, and uart.yaml. They're for controllers, not devices. These are copy-paste error from the corresponding device .yaml files. Piggyback some indentation consistency nits in binding-template.yaml. 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>

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>

bus: i2c
dts: bindings: provide generic yaml description for i2c-devices Provide generic yaml description for i2c-devices such as sensors New yaml binding category 'parent/child' is added. It aims at binding two types of related node such as bus master and bus slave. In case of i2c-device object, parent property is 'bus' with value 'i2c'. In the mean time, i2c node gets child property bus. Master and slave bus values should match. As such, 'i2c' node is bus master and 'i2c-devices' nodes are bus slaves Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>

i2c: Add submissions queue/completion queue bind To enable per peripheral queue pool sizing options add some bindings to the i2c controller to setup sq/cq pool sizing. Its possible this could go away with a shared application pair of pools. The shared pool would require some added function pointers though to deal with the variants as the shared pools would need a lock. Signed-off-by: Tom Burdick <thomas.burdick@intel.com>
