Bluetooth: btbcm: Add entry for BCM4335C0 UART bluetooth

2018-11-13T19:16:50+00:00

[ Upstream commit a357ea098c9605f60d92a66a9073f56ce25726da ] This patch adds the device ID for the AMPAK AP6335 combo module used in the 1st generation WeTek Hub Android/LibreELEC HTPC box. The WiFI chip identifies itself as BCM4339, while Bluetooth identifies itself as BCM4335 (rev C0): ``` [ 4.864248] Bluetooth: hci0: BCM: chip id 86 [ 4.866388] Bluetooth: hci0: BCM: features 0x2f [ 4.889317] Bluetooth: hci0: BCM4335C0 [ 4.889332] Bluetooth: hci0: BCM4335C0 (003.001.009) build 0000 [ 9.778383] Bluetooth: hci0: BCM4335C0 (003.001.009) build 0268 ``` Output from hciconfig: ``` hci0: Type: Primary Bus: UART BD Address: 43:39:00:00:1F:AC ACL MTU: 1021:8 SCO MTU: 64:1 UP RUNNING RX bytes:7567 acl:234 sco:0 events:386 errors:0 TX bytes:53844 acl:77 sco:0 commands:304 errors:0 Features: 0xbf 0xfe 0xcf 0xfe 0xdb 0xff 0x7b 0x87 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH SNIFF Link mode: SLAVE ACCEPT Name: 'HUB' Class: 0x0c0000 Service Classes: Rendering, Capturing Device Class: Miscellaneous, HCI Version: 4.0 (0x6) Revision: 0x10c LMP Version: 4.0 (0x6) Subversion: 0x6109 Manufacturer: Broadcom Corporation (15) ``` Signed-off-by: Christian Hewitt Signed-off-by: Marcel Holtmann Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

Bluetooth: btbcm: Fix handling of firmware not found

2016-02-23T19:29:37+00:00

If the call to request_firmware() fails in btbcm_setup_patchram(), the BCM chip will be operating with its default firmware. In this case, btbcm_setup_patchram() should not return immediately but instead should skip to btbcm_check_bdaddr() and quirk setup. Signed-off-by: Petri Gynther Signed-off-by: Marcel Holtmann

Bluetooth: btbcm: Read USB product information for Apple devices

2015-10-20T22:49:23+00:00

For the Apple Bluetooth devices, read the USB product information and print them. This allows for easy mapping of chip and USB details. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btbcm: Fix firmware version number calculation

2015-10-20T22:49:22+00:00

The calculation for the firmware version number is off by one bit. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btbcm: Read the local name in setup stage

2015-10-07T04:41:11+00:00

The Broadcom Bluetooth controllers have the chip name included in the ROM firmware or later in the patchram firmware. For debugging purposes read the local name and print it out. This is only done during setup stage and only once before loading the firmware and once after loading the firmware. For the Broadcom based controllers from Apple, the name is only read once after determining the chip id. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: btbcm: Send HCI Reset before sending Apple specific commands

2015-10-05T07:28:41+00:00

The commit 7bee8b08c428 allows the Read Verbose Config Info to fail gracefully and not cause the controller setup to abort. It seems the reason that command failed in the first place was the missing HCI Reset to bring the controller in full Bluetooth mode. Apple Bluetooth controllers start out in HID mode and when in that mode the Read Verbose Config Info command is not allowed. Sending HCI Reset switches the controller into full HCI mode.

Bluetooth: btbcm: Add BCM4330B1 UART device

Bluetooth: btbcm: allow btbcm_read_verbose_config to fail on Apple

2015-07-14T20:54:55+00:00

Commit 1c8ba6d013 moved around the setup code for broadcomm chips, and also added btbcm_read_verbose_config() to read extra information about the hardware. It's returning errors on some macbooks: Bluetooth: hci0: BCM: Read verbose config info failed (-16) Which makes us error out of the setup function. Since this probe isn't critical to operate the chip, this patch just changes things to carry on when it fails.

Bluetooth: btbcm: Add helper functions for UART setup

2015-06-06T05:33:25+00:00

Firmware loading may reset the controller UART speed and needs to set host UART speed back to init speed. UART drivers setup is split in 3 parts: - btbcm_initialize() resets the controller and returns the firmware name based on controller revision and sub_version. - btbtcm_patchram() (already existing and public), which takes the firmware name as parameter, requests the firmware and loads it to the controller. - btbcm_finalize() which resets the controller, reads local version and checks if the controller address is a default one or not. Remove firmware name retrieval for UART controllers from btbcm_setup_patchram(). Signed-off-by: Frederic Danis Signed-off-by: Marcel Holtmann
