Each bridge instance creates up to four auxiliary devices with different
names. However, their IDs are always zero, causing duplicate filename
errors when a system has multiple bridges:
sysfs: cannot create duplicate filename '/bus/auxiliary/devices/ti_sn65dsi86.gpio.0'
Fix this by using a unique instance ID per bridge instance. The
instance ID is derived from the I2C adapter number and the bridge's I2C
address, to support multiple instances on the same bus.

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.
