Where are you coming from with this question? The bindings previously didn't list a license, is there some implicit license for them? I would have thought it was GPL-2.0? IBM's (my employer's) preferred contribution license is GPL 2.0-or-later, so I was just adding the SPDX marker to clarify. > If so, the preference is to > dual license with (GPL-2.0 OR BSD-2-Clause).

Okay. I wouldn't have thought the ordering mattered. Is this just a preference? The tools seemed to run fine as is.

Yeah, I covered this in my cover letter. I was hoping to get away without that for the moment as this seems like the first pinctrl binding to be converted, however if you insist... > You need to define child nodes and list these > as values for 'function' and 'group'.

Or use patternProperties with '^(function|group)$'. Okay, I'll take some time to digest this while looking at the documentation. > > Similar comments apply to AST2500 binding. Yes, will fix that too. Thanks for the prompt review! Andrew
