- Texas Instruments PRUSS Ethernet MAC
- ====================================
- Required properties:
- - compatible : Should be one of the following,
- "ti,am3359-prueth" for AM335x SoCs
- "ti,am4376-prueth" for AM437x SoCs
- "ti,am57-prueth" for AM57xx SoCs
- "ti,k2g-prueth" for 66AK2G SoCs
- - pruss : Must point to a pruss device node
- - sram : pHandle to OCMC SRAM node
- - interrupt-parent : pHandle to the PRUSS INTC node
- Must contain children, one for each of the MAC ports.
- Required properties for children:
- - phy-handle : See ethernet.txt file in the same directory.
- - phy-mode : See ethernet.txt file in the same directory.
- - interrupt-names : should be "rx", "tx" and "ptp_tx".
- ptp_tx is optional.
- - interrupts : should contain an array of PRUSS system event
- numbers used as the interrupt sources for Rx,
- Tx and PTP Tx event packet timestamping (with
- PRP firmware) respectively.
- Optional properties for children:
- - local-mac-address : mac address for the port.
- Example (am572x-idk board):
- ===========================
- pruss2_eth {
- compatible = "ti,am57-prueth";
- pruss = <&pruss2>;
- sram = <&ocmcram1>;
- interrupt-parent = <&pruss2_intc>;
- pruss2_emac0: ethernet-mii0 {
- phy-handle = <&pruss2_eth0_phy>;
- phy-mode = "mii";
- interrupts = <20>, <22>, <23>;
- interrupt-names = "rx", "tx", "ptp_tx";
- /* Filled in by bootloader */
- local-mac-address = [00 00 00 00 00 00];
- };
- pruss2_emac1: ethernet-mii1 {
- phy-handle = <&pruss2_eth1_phy>;
- phy-mode = "mii";
- interrupts = <21>, <23>, <24>;
- interrupt-names = "rx", "tx", "ptp_tx";
- /* Filled in by bootloader */
- local-mac-address = [00 00 00 00 00 00];
- };
- };
