Kernel-4.18.0-80.el8_davinci_emac

• Texas Instruments Davinci EMAC

This file provides information, what the device node
for the davinci_emac interface contains.

Required properties:

• compatible: “ti,davinci-dm6467-emac”, “ti,am3517-emac” or
  “ti,dm816-emac”
• reg: Offset and length of the register set for the device
• ti,davinci-ctrl-reg-offset: offset to control register
• ti,davinci-ctrl-mod-reg-offset: offset to control module register
• ti,davinci-ctrl-ram-offset: offset to control module ram
• ti,davinci-ctrl-ram-size: size of control module ram
• interrupts: interrupt mapping for the davinci emac interrupts sources:

          4 sources: <Receive Threshold Interrupt
          Receive Interrupt
          Transmit Interrupt
          Miscellaneous Interrupt>
  

Optional properties:

• phy-handle: See ethernet.txt file in the same directory.

          If absent, davinci_emac driver defaults to 100/FULL.
  

• ti,davinci-rmii-en: 1 byte, 1 means use RMII
• ti,davinci-no-bd-ram: boolean, does EMAC have BD RAM?

eth0: emac@1e20000 {
compatible = “ti,davinci-dm6467-emac”;
reg = <0x220000 0x4000>;
ti,davinci-ctrl-reg-offset = <0x3000>;
ti,davinci-ctrl-mod-reg-offset = <0x2000>;
ti,davinci-ctrl-ram-offset = <0>;
ti,davinci-ctrl-ram-size = <0x2000>;
