Subject: [PATCH v2 1/2] Bluetooth: Option to enable power management from host
Date: Fri, 13 Aug 2010 12:06:47 +0530 [thread overview]
Message-ID: <1281681408-27376-1-git-send-email-suraj@atheros.com> (raw)
This provides a new option for hciattach to enable hardware specific
power management from host.
This option by default will be disabled for existing devices
