[PATCH V2 0/7] usb/acpi: Add binding usb device with acpi

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patchset's purppose is to bind usb device with associated
acpi node. The ACPI method "_PLD" and "_UPC" can be used to
identify usb port's connect type(hot-plug, hard-wired and
not-used). The patchset also can work on the port without device
connected.

This patchset derives from following patches.
