The ADV748x has two CSI-2 output port and one TTL input/output port for digital video reception/transmission. The TTL digital pad is unconditionally enabled during the device reset even if not used. Same goes for the TXA and TXB CSI-2 outputs, which are enabled by the initial settings blob programmed into the chip. In order to improve power saving, do not enable unused output interfaces: keep TTL output disabled, as it is not used, and drop CSI-2 output enabling from the initial settings list, as they get conditionally enabled later.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
