Now a warning in linux-next:
/builds/robherring/linux-dt/Documentation/devicetree/bindings/phy/qcom,ipq8074-qmp-pcie-phy.example.dtb:
phy at 84000: reg: [[0, 540672], [0, 4096]] is too long
from schema $id:
http://devicetree.org/schemas/phy/qcom,ipq8074-qmp-pcie-phy.yaml#
The default cell sizes are 1.
