| |
Add a switch to signal dock events to userspace.
Signed-off-by: Matthew Garrett <mjg@redhat.com>

I've done this as an input event rather than anything else since there isn't necessarily a terribly coherent concept of a dock device. HPs (for example) don't use ACPI for docking - the dock is simply an extension of devices that are already on the system. We can't sensibly create a dock platform device and then generate uevents on it. Doing it this way lets us standardise on a way to send docking events to userspace, which lets desktops do things like automatically expand onto external monitors when the system is docked.
