Bluetooth: hci_uart: Add Intel/AG6xx support

2016-02-24T15:34:23+00:00

This driver implements support for iBT2.1 Bluetooth controller embedded
in the AG620 communication combo. The controller needs to be configured
with bddata and can be patched with a binary patch file (pbn).
These operations are performed in manufacturing mode.

Bluetooth: hci_ldisc: Remove dead code

2015-12-09T23:51:50+00:00

The N_HCI ldisc does not define a flush_buffer() ldisc method, so
the check when opening the ldisc is always false.

Bluetooth: Use new hci_skb_pkt_* wrappers for drivers

2015-11-19T16:50:27+00:00

The new hci_skb_pkt_* wrappers are mainly intented for drivers to
require less knowledge about bt_cb(sbk) handling. So after converting
the core packet handling, convert all drivers.

Bluetooth: hci_uart: Provide initial manufacturer information

2015-10-21T04:20:44+00:00

Provide an early indication about the manufacturer information so that
it can be forwarded into monitor channel.

Bluetooth: Move handling of HCI_RUNNING flag into core

2015-10-05T07:30:25+00:00

Setting and clearing of HCI_RUNNING flag in each and every driver is
just duplicating the same code all over the place. So instead of having
the driver do it in their hdev->open and hdev->close callbacks, set it
globally in the core transport handling.

Bluetooth: Move HCI_RUNNING check into hci_send_frame

2015-10-05T07:30:10+00:00

In all callbacks for hdev->send the status of HCI_RUNNING is checked. So
instead of repeating that code in every driver, move the check into the
hci_send_frame function before calling hdev->send.

Bluetooth: Remove useless rx_lock spinlock

2015-09-24T14:25:44+00:00

rx_lock spinlock is only used in hci_uart_tty_receive() which is the
receive_buf ldisc callback.

hci_uart_tty_receive() is protected from re-entrance by its only
caller (flush_to_ldisc() in drivers/tty/tty_buffer.c) which held a
mutex (buf->lock) for this section.
This lock allows "safe use of the line discipline's receive_buf()
method by excluding the buffer work and any pending flush from using
the flip buffer." (comments from tty_buffer_lock_exclusive() in
drivers/tty/tty_buffer.c)

So, no need to double protect this resource with rx_lock.

Bluetooth: hciuart: Add support QCA chipset for UART

2015-08-10T21:52:20+00:00

QCA61x4 chips have supported sleep feature using In-Band-Sleep commands
to enable sleep feature based on H4 protocol. After sending
patch/nvm configuration is done, IBS mode will be up and running

Bluetooth: hci_uart: Add basic support for Intel Lightning Peak devices

2015-07-23T15:10:49+00:00

The Intel Lightning Peak devices do not come with Bluetooth firmware
loaded and thus require a full download of the operational Bluetooth
firmware when the device is attached via the Bluetooth line discipline.

Lightning Peak devices start with a bootloader mode that only accepts
a very limited set of HCI commands. The supported commands are enough
to identify the hardware and select the right firmware to load.
