1 * Renesas Electronics SH EtherMAC
3 This file provides information on what the device node for the SH EtherMAC
7 - compatible: "renesas,gether-r8a7740" if the device is a part of R8A7740 SoC.
8 "renesas,ether-r8a7778" if the device is a part of R8A7778 SoC.
9 "renesas,ether-r8a7779" if the device is a part of R8A7779 SoC.
10 "renesas,ether-r8a7790" if the device is a part of R8A7790 SoC.
11 "renesas,ether-r8a7791" if the device is a part of R8A7791 SoC.
12 "renesas,ether-r8a7794" if the device is a part of R8A7794 SoC.
13 "renesas,ether-r7s72100" if the device is a part of R7S72100 SoC.
14 - reg: offset and length of (1) the E-DMAC/feLic register block (required),
15 (2) the TSU register block (optional).
16 - interrupts: interrupt specifier for the sole interrupt.
17 - phy-mode: see ethernet.txt file in the same directory.
18 - phy-handle: see ethernet.txt file in the same directory.
19 - #address-cells: number of address cells for the MDIO bus, must be equal to 1.
20 - #size-cells: number of size cells on the MDIO bus, must be equal to 0.
21 - clocks: clock phandle and specifier pair.
22 - pinctrl-0: phandle, referring to a default pin configuration node.
25 - interrupt-parent: the phandle for the interrupt controller that services
26 interrupts for this device.
27 - pinctrl-names: pin configuration state name ("default").
28 - renesas,no-ether-link: boolean, specify when a board does not provide a proper
30 - renesas,ether-link-active-low: boolean, specify when the Ether LINK signal is
31 active-low instead of normal active-high.

39 interrupts = <0 162 IRQ_TYPE_LEVEL_HIGH>;
40 clocks = <&mstp8_clks R8A7790_CLK_ETHER>;
43 pinctrl-0 = <ðer_pins>;
44 pinctrl-names = "default";
45 renesas,ether-link-active-low;
49 phy1: ethernet-phy@1 {
51 interrupt-parent = <&irqc0>;
52 interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
53 pinctrl-0 = <&phy1_pins>;
54 pinctrl-names = "default";
