imx6dl怎么增加dm9000网卡驱动，linux系统3.14.28内核

杨帆！起航！

我的片选地址是0800 0000 中断是gpio4_5，设备树设置如下

    ethernet@0800040 {
        compatible = "davicom,dm9000";
        reg = <0x08000040 0x2 0x08000044 0x2>;
        interrupt-parent = <&gpio4>;
        interrupts = <5 2>;
        local-mac-address = [00 00 de ad be ef];
        davicom,no-eeprom;
    };

内核增加dm9000后，烧写开机logo如下

CAN device driver interface
dm9000 8000040.ethernet: read wrong id 0x01010101
eth0: dm9000a at c08fe040,c0912044 IRQ 261 MAC: 00:00:de:ad:be:ef (platform data
)
2188000.ethernet supply phy not found, using dummy regulator
pps pps0: new PPS source ptp0
fec 2188000.ethernet (unregistered net_device): Invalid MAC address: 00:00:00:00
:00:00

2e:16:3c:22
libphy: fec_enet_mii_bus: probed
fec 2188000.ethernet eth1: registered PHC device 0


然后ping测试
root@imx6dlsabresd:~# ifconfig eth0 192.168.88.186
root@imx6dlsabresd:~# ping 192.168.88.1
PING 192.168.88.1 (192.168.88.1): 56 data bytes



然后一直卡死没有任何信息，网口绿灯闪烁黄灯常量，求大神指导指导！！！

地址分配错误？                  

杨帆！起航！

OK 经过了2天多的时间终于搞定了！！！
&fec {     pinctrl-names = "default";     pinctrl-0 = <&pinctrl_enet_1>;     phy-mode = "rgmii";     status = "okay"; };

查看设备树增加文档，很重要啊
ls Documentation/devicetree/bindings/net/davicom-dm9000.txt

Required properties:
- compatible = "davicom,dm9000";
- reg : physical addresses and sizes of registers, must contain 2 entries:
    first entry : address register,
    second entry : data register.
- interrupt-parent : interrupt controller to which the device is connected
- interrupts : interrupt specifier specific to interrupt controller

Optional properties:
- local-mac-address : A bytestring of 6 bytes specifying Ethernet MAC address
    to use (from firmware or bootloader)
- davicom,no-eeprom : Configuration EEPROM is not available
- davicom,ext-phy : Use external PHY

Example:

    ethernet@18000000 {
        compatible = "davicom,dm9000";
        reg = <0x18000000 0x2 0x18000004 0x2>;
        interrupt-parent = <&gpn>;
        interrupts = <7 4>;
        local-mac-address = [00 00 de ad be ef];
        davicom,no-eeprom;
    };
