Hi all,

     I'm using LS2085A board. By default i2c bus 0 is selected , there we can able to read and write the register values.

     I need to read the register values from i2c bus 3.

     In u-boot i can able to read those registers. For selecting i2c bus 3 i used "i2c dev 3" command.

 

     But in kernel i can't able to select and read the i2c bus 3.I tried via accessing /dev/i2c-3 but i'm not getting.  I don't know how to select the bus 3.

 

     Can any one help me on this?

 

     Thanks in advance,

 

-Naveen
