Subject: [PATCH] usb device wakeup flags
Date: Thu, 27 Oct 2005 23:30:22 -0700 [thread overview]
Message-ID: <11304810223635@kroah.com> (raw)
In-Reply-To: <11304810222258@kroah.com>
[PATCH] usb device wakeup flags
This patch teaches "usb_device" about the new driver model wakeup support:
- It updates device wakeup capabilities when entering a configuration
with the WAKEUP attribute;
- During suspend processing it consults the policy bit to see
whether it should enable wakeup for that device. (This resolves
a FIXME to not assume the answer is always "yes"; some devices
lie about supporting remote wakeup.)
Support for root hubs and the HCDs is separate (and more complex).
