I'm trying to simplify ACPI drivers by reducing their dependence
on internal ACPI CA details. One possibility seems to be moving
notify handler management from individual drivers into the
Linux/ACPI driver registration code.
These patches add support for an ACPI driver .notify() method.
If one is present, the Linux/ACPI code installs a generic notify
handler when the driver binds to a device. The generic handler
passes the event on to the driver's .notify() method. The
advantage is that the driver need not install or remove the
notify handler, and the .notify() method works in terms of a
struct acpi_device rather than an acpi_handle.
Note that these patches only affect device notifications, not
system notifications. System notifications are primarily
bus-related events for things like hot-plug and wakeup. The
device notifications are generally driver-specific things like
"device status changed," "button pressed," or "some method
needs to be re-evaluated."
Comments welcome.
