On i.MX8QM/QXP/DXL SoCs, even a GPIO is selected as the wakeup source, the GPIO block will be powered off when system enters into suspend state. This can greatly reduce the power consumption of suspend state because the whole partition can be shutdown. This is called PAD wakeup feature on i.MX8x platform. This patch adds the noirq suspend/resume hooks and uses the pad wakeup feature as the default wakeup method for GPIO modules on i.MX8QM/QXP/DXL platforms.

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.
