* Renesas Electronics SH EtherMAC
This file provides information on what the device node for the SH EtherMAC
interface contains.
Required properties:
- compatible: "renesas,gether-r8a7740" if the device is a part of R8A7740 SoC.
"renesas,ether-r8a7743" if the device is a part of R8A7743 SoC.
"renesas,ether-r8a7745" if the device is a part of R8A7745 SoC.
"renesas,ether-r8a7778" if the device is a part of R8A7778 SoC.
"renesas,ether-r8a7779" if the device is a part of R8A7779 SoC.
"renesas,ether-r8a7790" if the device is a part of R8A7790 SoC.
"renesas,ether-r8a7791" if the device is a part of R8A7791 SoC.
"renesas,ether-r8a7793" if the device is a part of R8A7793 SoC.
"renesas,ether-r8a7794" if the device is a part of R8A7794 SoC.
"renesas,ether-r7s72100" if the device is a part of R7S72100 SoC.
- reg: offset and length of (1) the E-DMAC/feLic register block (required),
(2) the TSU register block (optional).
- interrupts: interrupt specifier for the sole interrupt.
- phy-mode: see ethernet.txt file in the same directory.
- phy-handle: see ethernet.txt file in the same directory.
- #address-cells: number of address cells for the MDIO bus, must be equal to 1.
- #size-cells: number of size cells on the MDIO bus, must be equal to 0.
- clocks: clock phandle and specifier pair.
- pinctrl-0: phandle, referring to a default pin configuration node.
Optional properties:
- interrupt-parent: the phandle for the interrupt controller that services
interrupts for this device.
- pinctrl-names: pin configuration state name ("default").
- renesas,no-ether-link: boolean, specify when a board does not provide a proper
Ether LINK signal.
- renesas,ether-link-active-low: boolean, specify when the Ether LINK signal is
active-low instead of normal active-high.
Example (Lager board):
ethernet@ee700000 {
compatible = "renesas,ether-r8a7790";
reg = <0 0xee700000 0 0x400>;
interrupt-parent = <&gic>;
interrupts = <0 162 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&mstp8_clks R8A7790_CLK_ETHER>;
phy-mode = "rmii";
phy-handle = <&phy1>;
pinctrl-0 = <ðer_pins>;
pinctrl-names = "default";
renesas,ether-link-active-low;
#address-cells = <1>;
#size-cells = <0>;
phy1: ethernet-phy@1 {
reg = <1>;
interrupt-parent = <&irqc0>;
interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
pinctrl-0 = <&phy1_pins>;
pinctrl-names = "default";
};
};
