Bluetooth: add quirk disabling LE Read Transmit Power

2022-01-16T08:11:13+00:00

commit d2f8114f9574509580a8506d2ef72e7e43d1a5bd upstream.

Some devices have a bug causing them to not work if they query
LE tx power on startup. Thus we add a quirk in order to not query it
and default min/max tx power values to HCI_TX_POWER_INVALID.

bluetooth: use dev_addr_set()

2021-10-25T18:01:29+00:00

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it go through appropriate helpers.

Bluetooth: Rename driver .prevent_wake to .wakeup

2021-10-01T22:46:15+00:00

prevent_wake logic is backward since what it is really checking is
if the device may wakeup the system or not, not that it will prevent
the to be awaken.

Also looking on how other subsystems have the entry as power/wakeup
this also renames the force_prevent_wake to force_wakeup in vhci driver.

Bluetooth: hci_sock: Replace use of memcpy_from_msg with bt_skb_sendmsg

2021-10-01T09:38:16+00:00

This makes use of bt_skb_sendmsg instead of allocating a different
buffer to be used with memcpy_from_msg which cause one extra copy.

Bluetooth: Make use of hci_{suspend,resume}_dev on suspend notifier

2021-09-29T13:50:14+00:00

This moves code from hci_suspend_notifier to hci_{suspend,resume}_dev
since some driver may handle pm directly using
HCI_QUIRK_NO_SUSPEND_NOTIFIER they would instead call
hci_{suspend,resume}_dev directly and we want that to have the same
behavior regardless of where pm is being handled.

Bluetooth: Fix handling of experimental feature for codec offload

2021-09-28T21:39:40+00:00

The existence of the experimental feature identifiy is the indication
that it is supported or not. No extra flag needed and the initial flag
should define if a feature is enabled or not. This is actually defined
in the management API definition.
