Hi! all
I use 82580EB whose i2c interface(SFP0_I2C_CLK,DATA) is connected to an i2c slave device.
I make igb driver as below,
[detail]
-Base ver:igb-5.2.9.4.tar.gz
-patches:add_i2cenable_parameter.patch
i2c_disables_oe_when_reading_scl_and_sda.patch
i2c_tristates_pins_for_high_value.patch
I try to check i2c interface as following steps,
(1)modprobe -r igb
(2)modprobe igb I2CBB=1
(3)modprobe i2c-dev
(4)i2cdetect - 0
-----------------------------result------------------------------------------
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-0.
I will probe address range 0x03-0x77.

I guess that "i2cdetect -y 0" detects 4 i2c interface. Because 82580 has 4 i2c interface.
But the result means that 5 i2c interface are detected.
I would like to know that what device is maeached to each chip address.
How should I confrm the relation between chip address and actual device ?
Best Regards,
