Qualcomm Ethernet ETHQOS device
This documents dwmmac based ethernet device which supports Gigabit
ethernet for version v2.3.0 onwards.
This device has following properties:
Required properties:
- compatible: Should be qcom,qcs404-ethqos"
- reg: Address and length of the register set for the device
- reg-names: Should contain register names "stmmaceth", "rgmii"
- clocks: Should contain phandle to clocks
- clock-names: Should contain clock names "stmmaceth", "pclk",
"ptp_ref", "rgmii"
- interrupts: Should contain phandle to interrupts
- interrupt-names: Should contain interrupt names "macirq", "eth_lpi"
Rest of the properties are defined in stmmac.txt file in same directory
Example:
ethernet: ethernet@7a80000 {
compatible = "qcom,qcs404-ethqos";
reg = <0x07a80000 0x10000>,
<0x07a96000 0x100>;
reg-names = "stmmaceth", "rgmii";
clock-names = "stmmaceth", "pclk", "ptp_ref", "rgmii";
clocks = <&gcc GCC_ETH_AXI_CLK>,
<&gcc GCC_ETH_SLAVE_AHB_CLK>,
<&gcc GCC_ETH_PTP_CLK>,
<&gcc GCC_ETH_RGMII_CLK>;
interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "macirq", "eth_lpi";
snps,reset-gpio = <&tlmm 60 GPIO_ACTIVE_LOW>;
snps,reset-active-low;
snps,txpbl = <8>;
snps,rxpbl = <2>;
snps,aal;
snps,tso;
phy-handle = <&phy1>;
phy-mode = "rgmii";
mdio {
#address-cells = <0x1>;
#size-cells = <0x0>;
compatible = "snps,dwmac-mdio";
phy1: phy@4 {
device_type = "ethernet-phy";
reg = <0x4>;
};
};
