This covers MAC address and maximal frame size properties. "local-mac-address" and "mac-address" with a fixed "address-size" of 48 bits are already in the ethernet-controller.yaml schema so move those over. Keep "address-size" fixed to 48 bits as it's unclear if network protocols using 64-bit mac addresses like ZigBee, 6LoWPAN and others are relevant for this binding. This allows mac address array size validation for ethernet and wireless lan devices. "max-frame-size" in the Devicetree Specification is written to cover the whole layer 2 ethernet frame but actual use for this property is the payload size. Keep the description from ethernet-controller.yaml which specifies the property as MTU. Signed-off-by: Janne Grunau --- Changes in v2: - Added "max-frame-size" with the description from ethernet-controller.yaml - Restrict "address-size" to 48-bits - Fix the mac-address array size to 6 bytes - Drop duplicate default value from "max-frame-size" description - Fix 2 nios2 dts files which incorrectly use the ethernet frame size of 1518 - Link to v1: https://lore.kernel.org/r/20230203-dt-bindings-network-class-v1-0-452e0375200d@jannau.net --- Janne Grunau (4): dt-bindings: net: Add network-class schema for mac-address properties dt-bindings: wireless: bcm4329-fmac: Use network-class.yaml schema dt-bindings: wireless: silabs,wfx: Use network-class.yaml nios2: dts: Fix tse_mac "max-frame-size" property .../bindings/net/ethernet-controller.yaml | 25 +----------- .../devicetree/bindings/net/network-class.yaml | 44 ++++++++++++++++++++++ .../bindings/net/wireless/brcm,bcm4329-fmac.yaml | 5 ++- .../bindings/net/wireless/silabs,wfx.yaml | 5 +-- arch/nios2/boot/dts/10m50_devboard.dts | 2 +- arch/nios2/boot/dts/3c120_devboard.dts | 2 +- 6 files changed, 52 insertions(+), 31 deletions(-) --- base-commit: 1b929c02afd37871d5afb9d498426f83432e71c2 change-id: 20230203-dt-bindings-network-class-8367edd679d2 Best regards,
