Hi, This fixes runtime PM and system-wide suspend for the cadence-qspi driver. Seeing how runtime PM and autosuspend are enabled by default, I believe this affects all users of the driver. The initial change has been split into three commits and a fourth commit is added to add system-wide suspend/resume callbacks. The MIPS platform at hand, used for debugging and testing, is currently not supported by the driver. It is the Mobileye EyeQ5 [0]. No code changes are required for support, only a new compatible and appropriate match data + flags. That will come later, with some performance-related patches.
