In exisiting code, the way to detect if driver/client reset should be executed or if hardware should be be soft resetted was overly complex. Existing code use to read the interrupt status register from task context to figure out if the interrupt source event was reset and then use clear the interrupt source for reset while waiting for the hardware to finish the reset. This behaviour again was confusing and overly complex in terms of the flow. This patch simplifies the handling of the requested reset and the pending reset(i.e. reset which have already been asserted by the software and hardware has acknowledged back to driver that it is processing the hardware reset through interrupt) Signed-off-by: Salil Mehta <salil.mehta@huawei.com> Signed-off-by: lipeng <lipeng321@huawei.com> Signed-off-by: David S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
