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: 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: Fix passing NULL to PTR_ERR

2021-09-21T08:44:52+00:00

Passing NULL to PTR_ERR will result in 0 (success), also since the likes of bt_skb_sendmsg does never return NULL it is safe to replace the instances of IS_ERR_OR_NULL with IS_ERR when checking its return.

Bluetooth: eir: Move EIR/Adv Data functions to its own file

2021-09-21T08:37:33+00:00

This moves functions manipulating EIR/Adv Data to its own file so it can be reused by other files. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: Add bt_skb_sendmmsg helper

2021-09-13T19:53:23+00:00

This works similarly to bt_skb_sendmsg but can split the msg into multiple skb fragments which is useful for stream sockets. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: Add bt_skb_sendmsg helper

2021-09-13T19:53:22+00:00

bt_skb_sendmsg helps takes care of allocation the skb and copying the the contents of msg over to the skb while checking for possible errors so it should be safe to call it without holding lock_sock. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: Configure codec for HFP offload use case

2021-09-07T21:09:18+00:00

For HFP offload use case, codec needs to be configured before opening SCO connection. This patch sends HCI_CONFIGURE_DATA_PATH command to configure doec before opening SCO connection. Signed-off-by: Kiran K Signed-off-by: Luiz Augusto von Dentz

Bluetooth: Allow setting of codec for HFP offload use case

2021-09-07T21:09:18+00:00

This patch allows user space to set the codec that needs to be used for HFP offload use case. The codec details are cached and the controller is configured before opening the SCO connection.
