Merge tag 'gemini-dts-update-2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into next/dt

Pull "A second set of Gemini DTS updates for v4.16" from Linus Walleij:

- Use Open Drain flags properly for emulated I2C

- Add the PCI bus to WBD111 and WBD222

- Enable the TVE and panel on DIR-685; the panel driver and
  bindings have been merged into the DRI subsystem.
