The I2C block in the Ux500 uses internal pull-ups on the SoC, in fact it has to: in HS mode, the I2C block will need to autonomously take control over the pull-up line to do its job. This can be clearly seen from the SoC manual which states that the silicon has a line named "en_cspu_hs" which enables current source pull-up for high speed mode. Another hint is that the vendor code tree never enabled the pull up on these lines, despite being deployed on boards that lack external pull-up resistors. Tested on the Ux500 reference designs without any problems.
