I've already made it a condition, as I refuse to blindly accept unknown bindings. Taking a sea of bindings I have no knowledge of would be a bad-thing(tm). If these were GPIO bindings, I'd be asking Linus for help, likewise if they were I2C, I'd be asking Wolfram. > > > Pretty much (plus generally being busy at ELC-E last week) - if there's > > > specific questions that's one thing but if it's just general requests to > > > look at bindings then it seems like the relevant subsystem maintainers > > > > This is exactly my point.

Now I know that jack detection is an Extcon thing and Extcon Ack will do just nicely. However, that begs the question; if they are an Extcon thing, why aren't they in the Extcon binding document? > > > should have the confidence to review straightfoward device properties > > > like this. > > > > I don't think these bindings are particularly straightforward.

My issue is that as they are not MFD related, I need some advice from my colleagues to whom they are related to. > The jack detection on these chips is fairly complex and there are > going to be plenty more patches before we have full support for > it in DT.

Put them in the subsystem where they pertain to -- job done. -- Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog
