Greg's already said that he'd be fine if I take the serial driver (patch 6/8) through the Tegra tree to resolve the dependencies. If you're okay with the three mailbox patches I can pick them up as well with your Acked-by. Otherwise, if you'd prefer to take these through the mailbox tree, let me know and I'll wait until sometime after v4.19-rc1 before I send out pull requests for the DT changes.
