[ Upstream commitfb31949693] Commitff4c371d2b("arm64: defconfig: Build ADMA and ACONNECT driver") enable the Tegra ADMA and ACONNECT drivers and this is causing resume from system suspend to fail on Jetson TX2. Resume is failing because the ACONNECT driver is being resumed before the BPMP driver, and the ACONNECT driver is attempting to power on a power-domain that is provided by the BPMP. While a proper fix for the resume sequencing problem is identified, disable the ACONNECT for Jetson TX2 temporarily to avoid breaking system suspend. Please note that ACONNECT driver is used by the Audio Processing Engine (APE) on Tegra, but because there is no mainline support for APE on Jetson TX2 currently, disabling the ACONNECT does not disable any useful feature at the moment.

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.
