* Bluetooth: Move handling of HCI_RUNNING flag into coreMarcel Holtmann2015-10-051-10/+1
| | | | | | | | | | 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_frameMarcel Holtmann2015-10-051-3/+0
| | | | | | | | | 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: Use MD SET register for changing SDIO Type-B to Type-AMarcel Holtmann2013-12-291-1/+2
| | | | | | | | | The register for setting the SDIO card mode of a Type-B Bluetooth card is called MD SET. The MD STAT register is used for reading the current mode back. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Set HCI_QUIRK_RESET_ON_CLOSE for Socket SDIO cardsMarcel Holtmann2013-12-231-0/+3
| | | | | | | | | | The Socket Bluetooth SDIO cards are branded versions of Toshiba SD-BT2 and they do not support sending HCI_Reset as first command. To make this card work the HCI_QUIRK_RESET_ON_CLOSE quirk needs to be set before registering the controller.

* Bluetooth: Add hdev parameter to hdev->send driver callbackMarcel Holtmann2013-10-111-2/+1
| | | | | | | | | | | | | | Instead of masking hdev inside the skb->dev parameter, hand it directly to the driver as a parameter to hdev->send. This makes the driver interface more clear and simpler. This patch fixes all drivers to accept and handle the new parameter of hdev->send callback. Special care has been taken for bpa10x and btusb drivers that require having skb->dev set to hdev for the URB transmit complete handlers.

* Bluetooth: Provide hdev parameter to hci_recv_frame() driver callbackMarcel Holtmann2013-10-111-2/+1
| | | | | | | | | | To avoid casting skb->dev into hdev, just let the drivers provide the hdev directly when calling hci_recv_frame() function. This patch also fixes up all drivers to provide the hdev. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Use devm_kzalloc in btsdio.c fileSachin Kamat2012-08-061-6/+2
| | | | | | | | | devm_kzalloc() eliminates the need to free memory explicitly thereby saving some cleanup code. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
* Bluetooth: Remove hci_dev->driver_dataDavid Herrmann2012-02-131-5/+5
| | | | | | | | | | The linux device model provides dev_set/get_drvdata so we can use this to save private driver data. This also removes several unnecessary casts.

* Bluetooth: Remove HCI-owner fieldDavid Herrmann2012-02-131-2/+0
| | | | | | | | | | | | | | | After unregistering an hci_dev object a bluetooth driver does not have any callbacks in the hci_dev structure left over. Therefore, there is no need to keep a reference to the module. Previously, we needed this to protect the hci-destruct callback. However, this callback is no longer available so we do not need this owner field, anymore. Drivers now call hci_unregister_dev() and they are done with the object.

* Bluetooth: btsdio: Free driver data on SDIO shutdownDavid Herrmann2012-02-131-10/+1
| | | | | | | | | | | | | Instead of waiting for the hdev object to get freed we now free the private driver-internal data on SDIO shutdown. This allows us to remove the obsolete hci-destruct callback and free our data object right away after calling hci_unregister_dev(). The HCI-core does not call any callbacks after this so we are never called again and can safely exit the module.

* Bluetooth: Convert controller hdev->type to hdev->busMarcel Holtmann2010-02-271-1/+1
| | | | | | | The hdev->type is misnamed and should be actually hdev->bus instead. So convert it now. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Enable per-module dynamic debug messagesMarcel Holtmann2008-11-301-5/+0
| | | | | | | | | | | With the introduction of CONFIG_DYNAMIC_PRINTK_DEBUG it is possible to allow debugging without having to recompile the kernel. This patch turns all BT_DBG() calls into pr_debug() to support dynamic debug messages. As a side effect all CONFIG_BT_*_DEBUG statements are now removed and some broken debug entries have been fixed.
