Drivers registered with module_platform_driver_probe() are considered non-hotpluggable, which among other things means that they don't support deferred probe. However, recent changes in how the ARM SMMU works have required the BPMP (which is the clock provider on Tegra186 and later) be bound to the SMMU, which in turn means that the BPMP driver can defer probe and hence clocks become available much later than they used to. For most other drivers this is not a problem because they already properly support deferred probe, but rtc-tegra is the odd one out that now fails to probe and will therefore never be registered. Fix this by making the driver a regular driver that supports unloading and deferred probe.

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.
