for this purpose I created a Matrix room here
https://matrix.to/#/#sdm845:ixit.cz?via=ixit.cz
I would like to mention, if you offering help with testing or #CI, you're welcome too!
I would like to use this room to solely focus on getting thing done and upstream into proper mainline kernel, so hopefully not a patches which stay more than 3 - 6 months within the tree (except the existing ones, needed for integration).
For the general discussion I would still recommend to use the original #sdm845:postmarketos.org
