Bjorn, please excuse my insistence. Given that it's not merged (yet),
probably it will not make it into 5.20. Is there anything preventing it
from being accepted for 5.21?
dwc patches were reviewed by Rob, Mani and Johan. Stanimir has acked the
bindings patch.
The dts patch should probably go via the arm-soc tree (together with
additional patches adding multiple MSI IRQs to other Qualcomm SoCs).
