It integrates 15 an Ethernet PHY core with a MAC and all the associated analog 16 circuitry, input and output clock buffering. 17 18 The ADIN2111 is a low power, low complexity, two-Ethernet ports 19 switch with integrated 10BASE-T1L PHYs and one serial peripheral 20 interface (SPI) port. The device is designed for industrial Ethernet 21 applications using low power constrained nodes and is compliant 22 with the IEEE 802.3cg-2019 Ethernet standard for long reach 23 10 Mbps single pair Ethernet (SPE). 24 25 The device has a 4-wire SPI interface for communication 26 between the MAC and host processor. 27 28allOf: 29 - $ref: ethernet-controller.yaml# 30 - $ref: /schemas/spi/spi-peripheral-props.yaml# 31 32properties: 33 compatible: 34 enum: 35 - adi,adin1110 36 - adi,adin2111 37 38 reg: 39 maxItems: 1 40 41 adi,spi-crc: 42 description: | 43 Enable CRC8 checks on SPI read/writes. 44 type: boolean 45 46 interrupts: 47 maxItems: 1 48 49 reset-gpios: 50 maxItems: 1 51 description: GPIO connected to active low reset 52 53required: 54 - compatible 55 - reg 56 - interrupts 57 58unevaluatedProperties: false 59 60examples: 61 - | 62 #include <dt-bindings/interrupt-controller/irq.h> 63 64 spi { 65 66 #address-cells = <1>; 67 #size-cells = <0>; 68 69 ethernet@0 { 70 compatible = "adi,adin2111"; 71 reg = <0>; 72 spi-max-frequency = <24500000>; 73 74 adi,spi-crc; 75 76 interrupt-parent = <&gpio>; 77 interrupts = <25 IRQ_TYPE_LEVEL_LOW>; 78 79 local-mac-address = [ 00 11 22 33 44 55 ]; 80 }; 81 }; 82
