Currently the TBU driver will only probe when CONFIG_ARM_SMMU_QCOM_DEBUG
is enabled. The driver not probing would prevent the platform to reach
sync_state and the system will remain in sub-optimal power consumption
mode while waiting for all consumer drivers to probe. To address this,
let's register the TBU driver in qcom_smmu_impl_init(), so that it can
probe, but still enable its functionality only when the debug option in
Kconfig is enabled.

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.
