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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
