2015-11-19Bluetooth: Use new hci_skb_pkt_* wrappers for driversMarcel Holtmann
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. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-10-21Bluetooth: hci_uart: Provide initial manufacturer informationMarcel Holtmann
Provide an early indication about the manufacturer information so that it can be forwarded into monitor channel. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-06-17Bluetooth: hci_uart: Fix dereferencing of ERR_PTRChan-yeol Park
If h4_recv_buf() return ERR_PTR instead sk_buff pointer, it should be cleared once PTR_ERR is completed for the further dereference such as h4_recv(), or h4_close(). Signed-off-by: Chan-yeol Park <chanyeol.park@samsung.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-04-30Bluetooth: hci_uart: Add Atheros support for address configurationMarcel Holtmann
The Atheros support for missing the support for configuration of the Bluetooth public address. Add support for the vendor specific command. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-04-30Bluetooth: hci_uart: Reorder Atheros specific driver callbacksMarcel Holtmann
The driver callbacks in the Atheros support were all in a random order and did not help readability of this driver. So reorder them to make them aligned with what other Bluetooth UART drivers do. This patch is not changing any actual code. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-04-07Bluetooth: hci_uart: Provide generic H:4 receive frameworkMarcel Holtmann
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.

2015-04-07Bluetooth: hci_uart: Remove the manual protocol init messageMarcel Holtmann
The init function for each HCI UART protocol prints the same on success and failure. This information is so generic, remove it and let the main HCI UART handling print it instead. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-04-07Bluetooth: hci_uart: Add name information to hci_uart_proto structMarcel Holtmann
This adds an extra name field to the hci_uart_proto struct that provides a simple way of adding a string identifier to the protocol. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-04-07Bluetooth: hci_uart: Make struct hci_uart_proto always constMarcel Holtmann
The usage of struct hci_uart_proto should always be const. Change the function headers and individual protocol drivers. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-04-07Bluetooth: hci_uart: Use h4_recv_buf helper for Atheros AR300xMarcel Holtmann
Instead of using hci_recv_stream_fragment, use the local available h4_recv_buf helper function. To ensure that the function is available select BT_HCIUART_H4. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-04-07Bluetooth: hci_uart: Use const data pointer for received dataMarcel Holtmann
The TTY layer provides its data pointers as const, but the HCI UART callbacks expect them as general data pointers. This is of course wrong and instead of casting them, just fix the individual drivers to actually take a const data pointer.

2015-02-02tty: Remove external interface for tty_set_termios()Peter Hurley
tty_set_termios() is an internal helper intended for file scope use. UART drivers which are capable of driving the RTS pin must properly handle the tiocmset() method, regardless of termios settings. A failure to do so is a UART driver bug and should be fixed there. Do not use this interface to workaround UART driver bugs.

Correct the comments in this driver. Set the CRTSCTS flag means automatic flow control is enabled. Signed-off-by: Fugang Duan <B38611@freescale.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2012-07-16tty: move the termios object into the ttyAlan Cox
This will let us sort out a whole pile of tty related races. The alternative would be to keep points and refcount the termios objects. However 1. They are tiny anyway 2. Many devices don't use the stored copies 3. We can remove a pty special case Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-02-13Bluetooth: hci-uart-ath: Use GFP_ATOMIC in open()David Herrmann
The uart_proto open() callback is not called in atomic context so we can safely sleep here. The caller hci_uart_set_proto() in hci_ldisc.c is an ioctl-handler and therefore can sleep.

2011-04-13Bluetooth: hci_uart: check the return value of recv()Jiejing Zhang
