[yocto] Compliance program questions

[Nicolas Dechesne]

Hi there,

I have a couple of questions regarding the compliance program. If
there is a better place for asking such questions, please let me know.

I have studied the Yocto compliance documentation, [1] on the website,
and I have the following questions:

 - is there any 'practical' guide with "do's and don'ts" to help make
a sucessful Yocto Project Compatible registration?
 - i understand that while the project should build with the OE core
toolchain, it is not required to use the OE core toolchain 'by
default', so we should be able to provide our own modified/customized
toolchain in our layers, is my understanding correct?
 - it is recommended, but not mandatory not use the Yocto kernel, so
we can use any mainline version in our BSP layers, right?
 - is it tolerated to change the versions of some components from
OE-core or meta-oe? Not just add patches through .bbappend, but
actually use an older or a more recent version of components, let's
say Gstreamer for example?
 - can we included new recipes for software programs not already
included in oe-core or meta-oe in our layers, or do we have to
contribute them back into oe-core or meta-oe before registration?
 - the Yocto project compatible registration is made against a
specific version of Yocto. What happens when a new Yocto version is
released? Should we go through the registration process again?

thanks a lot!
