1 MediaTek Frame Engine Ethernet controller
2 =========================================
4 The frame engine ethernet controller can be found on MediaTek SoCs. These SoCs
5 have dual GMAC each represented by a child node..
7 * Ethernet controller node
10 - compatible: Should be "mediatek,mt7623-eth"
11 - reg: Address and length of the register set for the device
12 - interrupts: Should contain the three frame engines interrupts in numeric
13 order. These are fe_int0, fe_int1 and fe_int2.
14 - clocks: the clock used by the core
15 - clock-names: the names of the clock listed in the clocks property. These are
16 "ethif", "esw", "gp2", "gp1"
17 - power-domains: phandle to the power domain that the ethernet is part of
18 - resets: Should contain a phandle to the ethsys reset signal
19 - reset-names: Should contain the reset signal name "eth"
20 - mediatek,ethsys: phandle to the syscon node that handles the port setup
21 - mediatek,pctl: phandle to the syscon node that handles the ports slew rate
25 - interrupt-parent: Should be the phandle for the interrupt controller
26 that services interrupts for this device
31 - compatible: Should be "mediatek,eth-mac"
32 - reg: The number of the MAC
33 - phy-handle: see ethernet.txt file in the same directory and
34 the phy-mode "trgmii" required being provided when reg
35 is equal to 0 and the MAC uses fixed-link to connect
36 with internal switch such as MT7530.
