Differently from other Aspeed drivers, this driver calls clock control APIs in interrupt context. Since ECLK is coupled with a reset bit in clk-aspeed module, aspeed_clk_enable will make 10ms of busy waiting delay for triggering the reset and it will eventually disturb other drivers' interrupt handling. To fix this issue, this commit changes this driver's irq to threaded irq so that the delay can be happened in a thread context.

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.
