This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit.
Indentation error I have rectified in my RFC v2.
Regarding below warnings
"Documentation/devicetree/bindings/usb/snps,dwc3.example.dts:86.27-89.15: Warning (unit_address_vs_reg): /example-2/usb@4a000000/multiport/mport@1: node has a unit name, but no reg or ranges property"
Here the mport expects no "reg" or ranges" property as of now. Only thing that is mandated is either the USB-PHY phandles using "usb-phy" or the Generic PHY declaration using "phy" and "phy-names"
Can you please suggest to mask these warnings or do I need to add something else ?
A unit-address requires 'reg' or 'ranges' and vice-versa. So you need
'reg'.
However, usb-hcd.yaml already defines what child nodes are for USB
hosts. Whatever you do here needs to be compatible with that.
Thanks for the info.
"@" is not actually a requirement for mport.
We can name them as "mport1" instead of "mport@1".
Now I do not see this reg, ranges warnings in latest PS v2
