Set GENPD_FLAG_ACTIVE_WAKEUP flag for domain psci cpuidle when OSI is activated, then when a device is set as the wake-up source using device_set_wakeup_path, the PSCI power domain could be retained to allow so that the associated device can wake up the system. With this flag, for S2IDLE system-wide suspend, the wake-up path is managed in each device driver and is tested in the power framework: a PSCI domain is only turned off when GENPD_FLAG_ACTIVE_WAKEUP is enabled and the associated device is not in the wake-up path, so PSCI CPUIdle selects the lowest level in the PSCI topology according to the wake-up path. This patch is a preliminary step to support PSCI OSI on the STM32MP25 platform with the D1 domain (power-domain-cluster) for the A35 cortex cluster and for the associated peripherals including EXTI1 which manages the wake-up interrupts for domain D1.

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 reStructuredText 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.
