The present suspend code disables the port interrupts and stops the HBA. On resume it enables the interrupts and HBA. This works fine until the FPD power domain is not off. If FPD is off then the ceva vendor specific configurations like OOB, AXI settings are lost, they need to be re-programmed and also since SERDES is also in FPD , SATA lane phy init needs to be called again (which is not happening in the present sequence) Because of this incorrect sequence SATA fails to work on resume. This patch corrects the code to make Suspend & Resume work in normal and FPD off cases.

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.
