Martí Bolívar 7165b77a81 scripts: edtlib: refactor for first class bindings ... Add two new types: Binding and PropertySpec. - Binding is a first-class abstraction for a devicetree binding file as defined by a YAML file in the Zephyr syntax. - PropertySpec is a helper type which represents a property definition within a Binding. Make the Binding constructor a new entry point to the library. This enables users to deal with bindings as standalone entities, apart from how they characterize a particular devicetree. Rework the EDT and Node internals that deal with bindings as dict values to use the Binding type instead. To make this less ambiguous, use the variable name 'raw' when we're dealing with a binding as it's parsed from YAML, and 'binding' when we're dealing with a Python Binding object. This commit drops support for the following legacy bindings keys - '#cells': use '*-cells' instead (e.g. 'gpio-cells', 'pwm-cells') - "child-bus: foo" and "child: bus: foo": use "bus:" instead - "parent-bus" and "parent: bus: ": use "on-bus:" instead Officially, legacy bindings have been gone since 6bf761fc0a ("dts: Remove support for deprecated DTS binding syntax"), so this is vestigial code, and I couldn't find any in-tree users. It also drops the convention in this file that ""-strings are preferred. I honestly don't understand why this was ever enforced; the file itself admits single quotes are common in Python and we use them elsewhere in Zephyr's Python code.
