Actually our DT node minimalist :
ethmac: ethernet@c9410000 {
compatible = "amlogic,meson-gxbb-dwmac",
"snps,dwmac-3.710", "snps,dwmac";
reg = <0x0 0xc9410000 0x0 0x10000
0x0 0xc8834540 0x0 0x4>;
interrupts = <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "macirq";
};
(I removed pinctrl, clocks and reset)
The dwmac bindings are quite complex, and we aren't sure how to describe
correctly the HW.
Could you point us on the right direction ?
Thanks,
Neil
