Compiler: TDA2X I2C2 timeout,and ETH1 ping blocked

Tool/software: TI C/C++ Compiler

Hi

      I  have a problem when i use i2c2 to configure RGMII/VIN2A pin-mux occording to datasheet.  Because i want to use eth1,and when i exec " ping  www.baidu.com" or " ping 192.168.42.1" ,blocked and with no response.

      Then i fond that RGMII1 is pin-muxed with VIN2A, and should use iic2 to configure.  What a pity ! IIC2 is pin-muxed with HDMI. And i test TP54,is high . According to spec,it means the module works on HDMI mode.I have tried to modify Device Tree,useless.  Why? At last i found that the driver "ti,dra7evm-tpd12s015" was returned at init function . That is to say, the driver didn't work well. 

      So,i am confused,how can i drive iic2 work correctly??? How can i make eth1 work correctly ? Pls give me a help. THX
