2012-08-27Bluetooth: Add support for Apple vendor-specific devicesHenrik Rydberg1-0/+3
As pointed out by Gustavo and Marcel, all Apple-specific Broadcom devices seen so far have the same interface class, subclass and protocol numbers. This patch adds an entry which matches all of them, using the new USB_VENDOR_AND_INTERFACE_INFO() macro. In particular, this patch adds support for the MacBook Pro Retina (05ac:8286), which is not in the present list.

2012-08-06Merge tty-next into 3.6-rc1Greg Kroah-Hartman16-56/+872
This handles the merge issue in: arch/um/drivers/line.c arch/um/drivers/line.h And resolves the duplicate patches that were in both trees do to the tty-next branch not getting merged into 3.6-rc1. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-07-17Bluetooth: Introduce a flags variable to Three-wire UART stateJohan Hedberg1-11/+15
This patch introduces a flags variable to the Three-wire UART state struct and converts the two existing bools in the struct into flags. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
2012-07-17Bluetooth: Improve Three-wire UART configuration handlingJohan Hedberg1-7/+27
The configuration request/response messages contain a configuration field which contains the sliding window size (amount of unacked reliable packets that can be pending). This patch makes sure that we configure the correct size (minimum of local and remote values) and use it when determining whether to send new packets or not.

2012-07-17Bluetooth: Remove unnecessary h5_build_pkt functionJohan Hedberg1-26/+23
The implementation of h5_build_packet can be moved into h5_prepare_pkt since all h5_prepare_pkt does is determine whether the packet is reliable and then call h5_build_packet. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
2012-07-17Bluetooth: Implement proper low-power support for Three-wire UARTJohan Hedberg1-5/+32
This patch adds on-demand wakeup request sending (and re-sendind) when we are in low-power state. When the controller enters this state it will send a sleep message after which the host is not allowed to send any other packets until a wakeup request has been sent and the woken message received as a response to it. The wakeup requests are re-sent periodically until a woken message is received. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
2012-07-17Bluetooth: Add initialization tracking to HCI Three-wire driverJohan Hedberg1-16/+50
This patch adds tracking for the uninitialized, initialized and active states for Three-wire UART. This is needed so we can handle periodic sending of the Link Establishment messages before reaching active state and so that we do not try to do any higher level HCI data transmission before reaching active state.

2012-07-17Bluetooth: Add initial sleep support to Three-wire UARTJohan Hedberg1-0/+13
This patch adds very basic support for the sleep related messages. The only thing the code does right now is send a wakeup message as soon as receiving a sleep one, essentially preventing the controller from going to sleep.

2012-07-17Bluetooth: Use delayed init for Three-wire UARTJohan Hedberg1-0/+3

2012-07-17Bluetooth: Add delayed init sequence support for UART controllersJohan Hedberg2-1/+43
This patch makes it possible to have UART drivers perform an internal initialization before calling hci_register_dev. This allows moving a lot of init code from user space (hciattach) to the kernel side, thereby creating a more controlled/robust initialization process.
