Dave, have you > given that a thought by any chance ? Could you point out the specific overlays? I'd suggest to add an example in= the bindings and/or sending a 'not to be picked-up' patch to the mailing lists showing how it's meant to work. That way people messing with that interface= can at least find it and work from there. See here for example Eric Anholt deal= ing with a similar issue as yours https://lkml.org/lkml/2016/12/14/483. I can't= say for other distributions, but in openSUSE we try to support the downstream overlays. BTW, is the I2C issue you mention related to this downstream patch 5bb4694516761 ('dt: Implement an I2C pinctrl mux for BSC0')? > Another more general question for Nicolas, is there a plan to try and > get vc04_services out of staging ? There's noone going at it seriously. I try to make the occasional cleanup h= ere and there, and the occasional patch might show up. But that's the extent of= it. I'm interested in biting the bullet but I've been fairly busy. Maybe this series can motivate people into investing more time into it :).
