Aside from the APB reference clock DW GPIO controller can have a dedicated clock connected to setup a debounce time interval for GPIO-based IRQs. Since this functionality is optional the corresponding clock source is also optional. Due to this lets handle the debounce clock in the same way as it has been developed for the APB reference clock, but using the bulk request/enable-disable methods.

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.
