Subject: [PATCH net-next] net: dt-bindings: ixp4xx-ethernet: Support fixed
 links

This ethernet controller is using fixed links for DSA switches
in two already existing device trees, so make sure the checker
does not complain like this:

intel-ixp42x-linksys-wrv54g.dtb: ethernet@...09000 (intel,ixp4xx-ethernet):
'fixed-link' does not match any of the regexes: '^pinctrl-[0-9]+$'
from schema $id: http://devicetree.org/schemas/net/intel,ixp4xx-ethernet.yaml#

intel-ixp42x-usrobotics-usr8200.dtb: ethernet@...0a000 (intel,ixp4xx-ethernet):
'fixed-link' does not match any of the regexes: '^pinctrl-[0-9]+$'
from schema $id: http://devicetree.org/schemas/net/intel,ixp4xx-ethernet.yaml#

Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202507040609.K9KytWBA-lkp@intel.com/
