I2C Ports in BB-xM

Hi,

This is regarding the I2C ports connectivity in BeagleBoard-xM.

DM3730 has 4 I2C ports. And in BeagleBoard-xM,
- I2C1_SDA/SCL and I2C4_SDA/SCL are used for power
management(according sections 7.7.3 and 7.7.4 of
  bb-xM Sys Ref Manual)
- I2C3_SDA/SCL is used for LCD interface(according section 7.17.1 of
bb-xM Sys Ref Manual)
- I2C2_SDA/SCL is used for Camera Port(according section 7.20 of bb-xM
Sys Ref Manual)

And according to section 7.24 of bb-xM Sys Ref Manual,
- I2C2_SDA/SCL is also available on Main Expansion Header

Could someone please clarify,
- if I2C2_SDA/SCL is shared for camera and expansion
- if camera is connected then the same is not available on expansion
- If I want to use I2C2 on expansion, what is to be done with I2C2
camera interface?

Thanks very much indeed in advance.
