Bluetooth: btsdio: Do not bind to non-removable BCM43341

2018-03-04T15:28:21Z

[ Upstream commit b4cdaba274247c9c841c6a682c08fa91fb3aa549 ] BCM43341 devices soldered onto the PCB (non-removable) always (AFAICT) use an UART connection for bluetooth. But they also advertise btsdio support on their 3th sdio function, this causes 2 problems: 1) A non functioning BT HCI getting registered 2) Since the btsdio driver does not have suspend/resume callbacks, mmc_sdio_pre_suspend will return -ENOSYS, causing mmc_pm_notify() to react as if the SDIO-card is removed and since the slot is marked as non-removable it will never get detected as inserted again. Which results in wifi no longer working after a suspend/resume. This commit fixes both by making btsdio ignore BCM43341 devices when connected to a slot which is marked non-removable.

Bluetooth: Use MD SET register for changing SDIO Type-B to Type-A

2013-12-29T19:31:07Z

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 Signed-off-by: Johan Hedberg

Bluetooth: Set HCI_QUIRK_RESET_ON_CLOSE for Socket SDIO cards

2013-12-23T16:49:35Z

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. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Add hdev parameter to hdev->send driver callback

2013-10-11T13:28:03Z

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. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Provide hdev parameter to hci_recv_frame() driver callback

2013-10-11T07:45:34Z

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 Signed-off-by: Johan Hedberg

Bluetooth: Use devm_kzalloc in btsdio.c file

2012-08-06T18:03:01Z

devm_kzalloc() eliminates the need to free memory explicitly thereby saving some cleanup code. Signed-off-by: Sachin Kamat Acked-by: Marcel Holtmann Signed-off-by: Gustavo Padovan

Bluetooth: Remove hci_dev->driver_data

2012-02-13T15:01:37Z

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. Signed-off-by: David Herrmann Acked-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Remove HCI-owner field

2012-02-13T15:01:24Z

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. Signed-off-by: David Herrmann Acked-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btsdio: Free driver data on SDIO shutdown

2012-02-13T15:01:24Z

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. Signed-off-by: David Herrmann Acked-by: Marcel Holtmann Signed-off-by: Johan Hedberg
