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

2018-02-16T19:23:06+00:00

commit b4cdaba274247c9c841c6a682c08fa91fb3aa549 upstream. 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: Rename HCI_BREDR into HCI_PRIMARY

2016-07-09T18:37:13+00:00

The HCI_BREDR naming is confusing since it actually stands for Primary Bluetooth Controller. Which is a term that has been used in the latest standard. However from a legacy point of view there only really have been Basic Rate (BR) and Enhanced Data Rate (EDR). Recent versions of Bluetooth introduced Low Energy (LE) and made this terminology a little bit confused since Dual Mode Controllers include BR/EDR and LE. To simplify this the name HCI_PRIMARY stands for the Primary Controller which can be a single mode or dual mode controller. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Use new hci_skb_pkt_* wrappers for drivers

2015-11-19T16:50:27+00:00

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 Signed-off-by: Johan Hedberg

Bluetooth: Move handling of HCI_RUNNING flag into core

2015-10-05T07:30:25+00:00

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

Bluetooth: Move HCI_RUNNING check into hci_send_frame

2015-10-05T07:30:10+00:00

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

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

2013-12-29T19:31:07+00:00

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

2013-12-23T16:49:35+00:00

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

2013-10-11T13:28:03+00:00

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

2013-10-11T07:45:34+00:00

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
