+ Sunplus SP7021 dual 10M/100M Ethernet MAC controller with Layer 2 switch.
+ The controller can operate at either dual Ethernet MAC mode or one Ethernet
+ MAC with layer 2 switch (daisy-chain) mode.
+ The device node of Sunplus SP7021 Ethernet (L2SW) MAC controller has
+ following properties.
+
+properties:
+ compatible:
+ const: sunplus,sp7021-l2sw
+
+ reg:
+ items:
+ - description: Base address and length of the L2SW registers.
+ - description: Base address and length of the MOON5 registers.
+
+ reg-names:
+ items:
+ - const: l2sw
+ - const: moon5
+
+ interrupts:
+ description: |
+ Contains number and type of interrupt. Number should be 66.
+ Type should be high-level trigger
+ maxItems: 1

+ pinctrl-names:
+ description: |
+ Names corresponding to the numbered pinctrl states.
+ A pinctrl state named "default" must be defined.
+ const: default
+
+ pinctrl-0:
+ description: A handle to the 'default' state of pin configuration
+
+ nvmem-cells:
+ items:
+ - description: nvmem cell address of MAC address of MAC 1
+ - description: nvmem cell address of MAC address of MAC 2

+ items:
+ - const: mac_addr0
+ - const: mac_addr1
+
+ mode:
+ description: |
+ Set operating modes of Sunplus Dual Ethernet MAC controller.
+ Please set one of the following modes:
+ 0: daisy-chain mode
+ 1: dual NIC mode
+ 2: daisy-chain mode but disable SA learning
