The DP83869 also supports 1000BASE-X and 20 100BASE-FX Fiber protocols. 21 This device interfaces to the MAC layer through Reduced GMII (RGMII) and 22 SGMII The DP83869HM supports Media Conversion in Managed mode. In this mode, 23 the DP83869HM can run 1000BASE-X-to-1000BASE-T and 100BASE-FX-to-100BASE-TX 24 conversions. The DP83869HM can also support Bridge Conversion from RGMII to 25 SGMII and SGMII to RGMII. 26 27 Specifications about the Ethernet PHY can be found at: 28 http://www.ti.com/lit/ds/symlink/dp83869hm.pdf 29 30properties: 31 reg: 32 maxItems: 1 33 34 ti,min-output-impedance: 35 type: boolean 36 description: | 37 MAC Interface Impedance control to set the programmable output impedance 38 to a minimum value (35 ohms). 39 40 ti,max-output-impedance: 41 type: boolean 42 description: | 43 MAC Interface Impedance control to set the programmable output impedance 44 to a maximum value (70 ohms). 45 46 tx-fifo-depth: 47 $ref: /schemas/types.yaml#/definitions/uint32 48 description: | 49 Transmitt FIFO depth see dt-bindings/net/ti-dp83869.h for values 50 51 rx-fifo-depth: 52 $ref: /schemas/types.yaml#/definitions/uint32 53 description: | 54 Receive FIFO depth see dt-bindings/net/ti-dp83869.h for values 55 56 ti,clk-output-sel: 57 $ref: /schemas/types.yaml#/definitions/uint32 58 description: | 59 Muxing option for CLK_OUT pin see dt-bindings/net/ti-dp83869.h for values. 60 61 ti,op-mode: 62 $ref: /schemas/types.yaml#/definitions/uint32 63 description: | 64 Operational mode for the PHY.
