MediaTek Frame Engine Ethernet controller
|
|
=========================================
|
|
|
|
The frame engine ethernet controller can be found on MediaTek SoCs. These SoCs
|
|
have dual GMAC each represented by a child node..
|
|
|
|
* Ethernet controller node
|
|
|
|
Required properties:
|
|
- compatible: Should be
|
|
"mediatek,mt2701-eth": for MT2701 SoC
|
|
"mediatek,mt7623-eth", "mediatek,mt2701-eth": for MT7623 SoC
|
|
"mediatek,mt7622-eth": for MT7622 SoC
|
|
- reg: Address and length of the register set for the device
|
|
- interrupts: Should contain the three frame engines interrupts in numeric
|
|
order. These are fe_int0, fe_int1 and fe_int2.
|
|
- clocks: the clock used by the core
|
|
- clock-names: the names of the clock listed in the clocks property. These are
|
|
"ethif", "esw", "gp2", "gp1" : For MT2701 and MT7623 SoC
|
|
"ethif", "esw", "gp0", "gp1", "gp2", "sgmii_tx250m", "sgmii_rx250m",
|
|
"sgmii_cdr_ref", "sgmii_cdr_fb", "sgmii_ck", "eth2pll" : For MT7622 SoC
|
|
- power-domains: phandle to the power domain that the ethernet is part of
|
|
- resets: Should contain phandles to the ethsys reset signals
|
|
- reset-names: Should contain the names of reset signal listed in the resets
|
|
property
|
|
These are "fe", "gmac" and "ppe"
|
|
- mediatek,ethsys: phandle to the syscon node that handles the port setup
|
|
- mediatek,sgmiisys: phandle to the syscon node that handles the SGMII setup
|
|
which is required for those SoCs equipped with SGMII such as MT7622 SoC.
|
|
- mediatek,pctl: phandle to the syscon node that handles the ports slew rate
|
|
and driver current
|
|
|
|
Optional properties:
|
|
- interrupt-parent: Should be the phandle for the interrupt controller
|
|
that services interrupts for this device
|
|
* Ethernet MAC node
|
|
|
|
Required properties:
|
|
- compatible: Should be "mediatek,eth-mac"
|
|
- reg: The number of the MAC
|
|
- phy-handle: see ethernet.txt file in the same directory and
|
|
the phy-mode "trgmii" required being provided when reg
|
|
is equal to 0 and the MAC uses fixed-link to connect
|
|
with internal switch such as MT7530.
|
|
|
|
Example:
|
|
|
|
eth: ethernet@1b100000 {
|
|
compatible = "mediatek,mt7623-eth";
|
|
reg = <0 0x1b100000 0 0x20000>;
|
|
clocks = <&topckgen CLK_TOP_ETHIF_SEL>,
|
|
<ðsys CLK_ETHSYS_ESW>,
|
|
<ðsys CLK_ETHSYS_GP2>,
|
|
<ðsys CLK_ETHSYS_GP1>;
|
|
clock-names = "ethif", "esw", "gp2", "gp1";
|
|
interrupts = <GIC_SPI 200 IRQ_TYPE_LEVEL_LOW
|
|
GIC_SPI 199 IRQ_TYPE_LEVEL_LOW
|
|
GIC_SPI 198 IRQ_TYPE_LEVEL_LOW>;
|
|
power-domains = <&scpsys MT2701_POWER_DOMAIN_ETH>;
|
|
resets = <ðsys MT2701_ETHSYS_ETH_RST>;
|
|
reset-names = "eth";
|
|
mediatek,ethsys = <ðsys>;
|
|
mediatek,pctl = <&syscfg_pctl_a>;
