The R1 and R3 lines drive NMOS transistors that are OFF with a low level.
On the SAMA5D2 Xplained board, if the pins corresponding to R1 and R3
have pull-ups enabled, there is an extra 2 x 30uA power consumption.
Use pull-downs for these 2 lines to remove the unnecessary power
consumption.
Fixes: b133ca7a65 ("ARM: dts: at91: sama5d2_xplained: add pin muxing and enable classd")

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.
