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: 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.

Bluetooth: hci_uart: Add new line discipline enhancements

2015-06-17T21:44:49+00:00

Added the ability to flow control the UART, improved the UART baud
rate setting, transferred the speeds into line discipline from the
protocol and introduced the tty init function.

Bluetooth: hci_uart: Support operational speed during setup

2015-06-06T05:30:12+00:00

Add initial and operational speeds.
Change to operational speed as soon as possible. If controller
set_baudrate() fails, continue at initial speed.

Bluetooth: hci_uart: Use generic Intel support for address setting

2015-04-07T16:48:21+00:00

The Bluetooth address setting for Intel devices is provided by a generic
module now. Start using that module instead of relying it being included
in the driver.

Bluetooth: hci_uart: Provide generic H:4 receive framework

2015-04-07T16:48:21+00:00

Future H:4 based UART drivers require custom packet types and custom
receive functions. To support this, extended the h4_recv_buf function
with a packet definition table.

For the default H:4 packets types of ACL data, SCO data and events,
provide helpers to reduce the amount of code duplication.

Bluetooth: hci_uart: Add protocol support for Broadcom UART devices

2015-04-07T16:47:12+00:00

This adds the protocol support for Broadcom based UART devices to
enable firmware and patchram download procedure. It is a pretty
straight forward H:4 driver with the exception of actually having
its own setup and address configuration callbacks.

Bluetooth: hci_uart: Move setup callback into different location

2015-04-07T16:47:11+00:00

The setup callback got wrongly inserted between the enqueue and dequeue
callbacks. Move it to a better location.
