On bluesleep stop, EXT_WAKE gpio will be set to default high level. This condition does not allow BT chip to enter low power mode. So, start and stop bluesleep based on HCI_DEV_REG and HCI_DEV_UNREG events instead of HCI_DEV_UP and HCI_DEV_DOWN. Also, enable and disable host wake functionality based on HCI_DEV_UP and HCI_DEV_DOWN events, as these events indicate BT turn ON and OFF Bug 1014590 Change-Id: I3929c1328ac024eb080359283107dabf3712e9ea Signed-off-by: Nagarjuna Kristam <nkristam@nvidia.com> Reviewed-on: http://git-master/r/114984 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Rakesh Kumar <krakesh@nvidia.com> Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>
