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 h4_recv_buf helper for H:4 protocolMarcel Holtmann

2015-04-07Bluetooth: hci_uart: Introduce h4_recv_buf helper functionMarcel Holtmann
The h4_recv_buf helper function can be used for receiving H:4 packets out of a TTY stream. It is self-contained and allows for reuse by all HCI UART protocols. 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.

2015-04-07Bluetooth: hci_uart: Remove unused h4->rx_state and h4->rx_count fieldMarcel Holtmann

2015-04-07Bluetooth: hci_uart: Remove unused h4->rx_skb fieldMarcel Holtmann
The h4->rx_skb is not used anymore and with that just remove it. Seems this was a leftover and even the kfree_skb call freeing it is rather pointless since it got never allocated. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2015-04-07Bluetooth: hci_uart: Add support for vendor detection flagMarcel Holtmann
This adds a new HCI_UART_VND_DETECT flag to allow automatic vendor detection. This allows to enable known vendor commands (for example for setting the public device address) when using a standard H:4 UART protocol or when running in virtual machines. When this new flag is configured and no vendor specific setup routine is provided, then the local version information are read and the provided manufacturer information can be evaluated to configure extra vendor callbacks.

2015-03-03Bluetooth: btusb: Add support for QCA ROME chipset familyKim, Ben Young Tae
This patch supports ROME Bluetooth family from Qualcomm Atheros, e.g. QCA61x4 or QCA6574. New chipset have similar firmware downloading sequences to previous chipset from Atheros, however, it doesn't support vid/pid switching after downloading the patch so that firmware needs to be handled by btusb module directly. ROME chipset can be differentiated from previous version by reading ROM version.

2015-02-15Bluetooth: btusb: Use matching names for Broadcom firmware filesMarcel Holtmann
The Broadcom firmware files are named with firmware version information encoded into lmp_subver field. So BCM20702B0_002.001.014.0527.0607.hex would be represented by 0x410e. To allow for an easier decoding of the actual firmware names, provide an internal table that does the mapping and request the firmware file by name. Bluetooth: hci0: BCM20702B0 (002.001.014) build 0607 Now the complicated encoding of lmp_subver will be decoded and turned into the name and firmware version information from the firmware files. The previous attempt of using udev->product failed badly since it never contains any matching entry to the actual hardware or firmware files distributed by Broadcom in their Windows drivers. It is even worse since it can change depending on if the internal bootstrapping happened before the USB bus enumeration or after. This caused many race conditions.

2015-02-15Bluetooth: Add device shutdown routine for Intel Bluetooth deviceTedd Ho-Jeong An
This patch adds the device shutdown routine for Intel Bluetooth device. Some platforms have BT LED issue with Intel Bluetooth device that BT LED goes off 5 seconds after BT is turned off For Intel Bluetooth device, the BT LED is turned off when: - there is no active connection or radio activity - USB is suspend So, when the BT is turned off, it takes 5 seconds because USB suspend timeone is 5 seconds by default. And if the USB suspend is not enabled, BT LED won't be turned off. To fix this issue, recently Intel Bluetooth firmware patch had been submitted to turn off the BT LED immediately by the vendor specific command(0xFC3F). And this patch sends this command to the device before closing the device. For backward compatibility of this command with old firmware, this command was supported before, but it behaves same as HCI_RESET internally. So, it won't be the problem even if the system doesn't have the latest firmware patch. Signed-off-by: Tedd Ho-Jeong An <tedd.an@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

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.

2015-01-30Bluetooth: btusb: Use wait_on_bit_timeout() for BTUSB_BOOTINGJohan Hedberg
The wait_on_bit_timeout() is a simpler and race-free way of waiting for a bit to be cleared than the current code in btusb.c. This patch updates the code to use the helper function (its btusb copy - to be later updated to use a global one).

2015-01-30Bluetooth: btusb: Fix race when waiting for BTUSB_DOWNLOADINGJohan Hedberg
The test for BTUSB_DOWNLOADING must be after adding to the wait queue and setting the TASK_INTERRUPTIBLE state. Otherwise the flag may get cleared after we test for it and we end up getting a timeout since schedule_timeout() waits for the full duration. This patch uses a wait_on_bit_timeout() + wake_up_bit(). To perform the task both race-free as well as in a much simpler way. Since there's no global wait_on_bit_timeout() helper yet (even though all the building blocks for it are in place) this patch creates a temporary local btusb copy of it until the global one has made it to upstream trees.

BugLink: https://bugs.launchpad.net/bugs/1400215 ath3k devices fail to load firmwares on xHCI buses, but work well on EHCI, this might be a compatibility issue between xHCI and ath3k chips. As my testing result, those chips will work on xHCI buses again with this patch. This workaround is from Qualcomm, they also did some workarounds in Windows driver.

2015-01-29Bluetooth: btusb: Ignore unknown Intel devices with generic descriptorMarcel Holtmann
The Intel Bluetooth devices use the generic USB device/interface class descriptors that are assigned to Bluetooth H:2 conforming transports.

To avoid any confusion for the users, just ignore unknown Intel Bluetooth devices. All the released Intel Bluetooth devices have an entry in the device table identifying their setup and support requirements. The advantage here is that older kernel can be booted with newer devices without causing any disturbance.

2015-01-28Bluetooth: btusb: Provide hardware error handler for Intel devicesMarcel Holtmann
The Intel Bluetooth controllers can provide an additional exception info string when a hardware error event occurs. The core will now call hdev->hw_error to let the driver read out this information. This change will cause a reset of the hardware to bring it back into functional state and then read the Intel exception info string and print it along with the error information.

2015-01-28Bluetooth: btusb: Remove redundant call to btusb_free_frags()Johan Hedberg
The btusb_disconnect() callback calls hci_unregister_dev() which in turn calls btusb_close() if the HCI device is powered. The btusb_close() function in turn will call btusb_free_frags(). It's therefore unnecessary to have another call to btusb_free_frags() in the btusb_disconnect() function. Besides the redundancy the second call seems to also cause some strange stability issues which this patch then also fixes.
