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.

dts: bindings: Fix xlnx,ttcps binding compat The `xlnx,ttcps` binding, despite having the file name of `xlnx,ttcps.yaml`, had the compatible property of `cdns,ttc`. While it is true that the Xilinx ZynqMP platform embeds the Cadence Triple Timer Counter (TTC) IP core, its TTC differs from the original Cadence core in that it implements 32-bit counters, instead of the 16-bit counters defined in the original; hence, the Xilinx variant is not compatible with the original Cadence version and should be treated as a different device. This commit changes the `xlnx,ttcps.yaml` compatible property to `xlnx,ttcps` for the above reasons. Signed-off-by: Stephanos Ioannidis <root@stephanos.io>

compatible: "xlnx,ttcps"
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>
