I don't see this happening tho. Sadly, there are closed source components in the products which are under NDA's, and even if the company wanted they wouldn't be able to open source some stuff.
I don't expect LG to open something that doesn't belong to them and I'm pretty sure that no matter what some drivers will remain closed source. That's fine. But still a HUGE help will be releasing schematics, GPIO usage, kernel configuration files and so on... You don't need everything open sourced to keep maintaining support.
