Convert lan9303.txt to yaml format to fix below CHECK_DTBS warnings: arch/arm/boot/dts/nxp/imx/imx53-kp-hsc.dtb: /soc/bus@50000000/i2c@53fec000/switch@a: failed to match any schema with compatible: ['smsc,lan9303-i2c'] Additional changes: - rename switch-phy to switch in example.

dt-bindings: net: dsa: remove obsolete dsa.txt

2026-06-05T01:17:15+00:00

dsa.txt has been a redirect to dsa.yaml since commit bce58590d1bd ("dt-bindings: net: dsa: Add DSA yaml binding") introduced the .yaml schema. The .yaml has the same filename in the same directory, making this redirect unnecessary for discoverability. Two files still reference dsa.txt, forcing readers through an extra hop to reach the .yaml. The stub has not been touched since August 2020. Update references in lan9303.txt and Documentation/networking/dsa/dsa.rst to point directly to dsa.yaml and remove the stub.

net: dsa: Use conduit and user terms

2023-10-24T20:08:14+00:00

Use more inclusive terms throughout the DSA subsystem by moving away from "master" which is replaced by "conduit" and "slave" which is replaced by "user". No functional changes.
