Bibby Hsieh 6058f11870 mailbox: mediatek: cmdq: clear the event in cmdq initial flow
GCE hardware stored event information in own internal sysram,
if the initial value in those sysram is not zero value
it will cause a situation that gce can wait the event immediately
after client ask gce to wait event but not really trigger the
corresponding hardware.

In order to make sure that the wait event function is
exactly correct, we need to clear the sysram value in
cmdq initial flow.

README

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.
