For example, creating an IRQ resource with a flag that marks the interrupt as wake capable. Add a set of macros to provide custom flag arguments.

Use resource flags to provide this information to the caller if they want it. This should keep the API more robust over time as flags are added, modified, or removed. It also more closely matches acpi_irq_get() which take a resource as an argument. Rename the function to acpi_dev_get_gpio_irq_resource() to better describe the function's new behavior.

The intention was not to fix any particular interrupt as wakeup capable but leave those details to the device. It wasn't intended to enforce any rules as what can be or can't be a wakeup interrupt. Soften the wording to not mandate that the 'wakeup-source' property be used, and clarify what it means when an interrupt is marked (or not marked) for wakeup.

It is planned to update the driver to no longer assume that the EC interrupt pin should be enabled for wake. Add the wakeup-source property to all cros-ec-spi compatible device nodes to signify to the driver that they should still be a valid wakeup source.

Some Chromebooks use a separate wake pin, while others overload the interrupt for wake and IO. With the current assumption, spurious wakes can occur on systems that use a separate wake pin. It is planned to update the driver to no longer assume that the EC interrupt pin should be enabled for wake. Add the wakeup-source property to all cros-ec-spi compatible device nodes to signify to the driver that they should still be a valid wakeup source.

Wake capability is assumed based on conventions provided in the devicetree wakeup-source binding documentation. An interrupt is considered wake capable if the following are true: 1. A wakeup-source property exits in the same device node as the interrupt. 2. The IRQ is marked as dedicated by setting its interrupt-name to "wakeup". The wakeup-source documentation states that dedicated interrupts can use device specific interrupt names and device drivers are still welcome to use their own naming schemes. This API is provided as a helper if one is willing to conform to the above conventions. The ACPI subsystems already provides similar APIs that allow one to query the wake capability of an IRQ. This brings closer feature parity to the devicetree.

Modify the driver to use the power management subsystem to manage the wakeirq. Rather than assuming that the IRQ is wake capable, use the underlying firmware/device tree to determine whether or not to enable it as a wake source. Some Chromebooks rely solely on the ec_sync pin to wake the AP but do not specify the interrupt as wake capable in the ACPI _CRS. For LPC/ACPI based systems a DMI quirk is introduced listing boards whose firmware should not be trusted to provide correct wake capable values. For device tree base systems, it is not an issue as the relevant device tree entries have been updated and DTS is built from source for each ChromeOS update.
