Stephan Gerhold 48277423e5 dt-bindings: i2c: qcom,i2c-qup: Document power-domains
Similar to qcom,geni-i2c, for i2c-qup we need to vote for performance
states on the VDDCX power domain to ensure that required clock rates
can be generated correctly.

I2C is typically used with a fixed clock rate, so a single required-opp
is sufficient without a full OPP table (unlike spi-qup for example).

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 reStructuredText 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.
