[PATCH 1/1] dt-bindings: usb: microchip,usb2514: Fix reference USB device schema

[Alexander Stein]

An USB hub is not a HCD, but an USB device. Fix the referenced schema
accordingly. Adjust example to keep it aligned to other schemas.

Fixes: bfbf2e4b77e27 ("dt-bindings: usb: Document the Microchip USB2514 hub")
Signed-off-by: Alexander Stein <alexander.stein@ew.tq-group.com>
---
As this USB hub also can contain an USB (ethernet) sub device, I copied
the subdevice part from usb-hcd.yaml.

I had to add 'additionalProperties: true' as well, because I got that warning
upon dt_binding_check otherwise:
> Documentation/devicetree/bindings/usb/microchip,usb2514.yaml: 
>   ^.*@[0-9a-f]{1,2}$: Missing additionalProperties/unevaluatedProperties constraint

I added a Fixes tag to keep this schema aligned in v6.10 stable tree.

Hi,

This is the friendly patch-bot of Greg Kroah-Hartman.  You have sent him
a patch that has triggered this response.  He used to manually respond
to these common problems, but in order to save his sanity (he kept
writing the same thing over and over, yet to different people), I was
created.  Hopefully you will not take offence and will fix the problem
in your patch and resubmit it so that it can be accepted into the Linux
kernel tree.

You are receiving this message because of the following common error(s)
as indicated below:

- You have marked a patch with a "Fixes:" tag for a commit that is in an
  older released kernel, yet you do not have a cc: stable line in the
  signed-off-by area at all, which means that the patch will not be
  applied to any older kernel releases.  To properly fix this, please
  follow the documented rules in the
  Documentation/process/stable-kernel-rules.rst file for how to resolve
  this.

If you wish to discuss this problem further, or you have questions about
how to resolve this issue, please feel free to respond to this email and
Greg will reply once he has dug out from the pending patches received
from other developers.

thanks,

greg k-h's patch email bot

This is not needed. Both are correct - usb-hub and hub. I prefer not to
rename all "phy" nodes to "usb-phy" and vice versa.

Rest is good, so with dropping this renaming hunk:

checkpatch.pl complains the hash is 13 chars rather than 12.
