2020-03-08Bluetooth: Enable erroneous data reporting if WBS is supportedAlain Michaud
This change introduces a wide band speech setting which allows higher level clients to query the local controller support for wide band speech as well as set the setting state when the radio is powered off. Internally, this setting controls if erroneous data reporting is enabled on the controller. Signed-off-by: Alain Michaud <alainm@chromium.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

This patch replaces devm_gpiod_get() with devm_gpiod_get_optional() to get bt_en and replaces devm_clk_get() with devm_clk_get_optional() to get susclk.

2020-02-28Bluetooth: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2020-01-24Bluetooth: btrtl: Use kvmalloc for FW allocationsMaxim Mikityanskiy
Currently, kmemdup is applied to the firmware data, and it invokes kmalloc under the hood. The firmware size and patch_length are big (more than PAGE_SIZE), and on some low-end systems (like ASUS E202SA) kmalloc may fail to allocate a contiguous chunk under high memory usage and fragmentation: Bluetooth: hci0: RTL: examining hci_ver=06 hci_rev=000a lmp_ver=06 lmp_subver=8821 Bluetooth: hci0: RTL: rom_version status=0 version=1 Bluetooth: hci0: RTL: loading rtl_bt/rtl8821a_fw.bin kworker/u9:2: page allocation failure: order:4, mode:0x40cc0(GFP_KERNEL|__GFP_COMP), nodemask=(null),cpuset=/,mems_allowed=0 <stack trace follows> As firmware load happens on each resume, Bluetooth will stop working after several iterations, when the kernel fails to allocate an order-4 page. This patch replaces kmemdup with kvmalloc+memcpy. It's not required to have a contiguous chunk here, because it's not mapped to the device directly.

It will power-off the BT chip during hci down and power-on/initialize the chip again during hci up.

2020-01-15Bluetooth: hci_qca: Retry btsoc initialize when it failsRocky Liao
This patch adds the retry of btsoc initialization when it fails. There are reports that the btsoc initialization may fail on some platforms but the repro ratio is very low. The symptoms is the firmware downloading failed due to the UART write timed out. The failure may be caused by UART, platform HW or the btsoc itself but it's very difficlut to root cause, given the repro ratio is very low. Add a retry for the btsoc initialization can work around most of the failures and make Bluetooth finally works.

Driver supports BCM4329, but there is no device-tree compatible for that chip. Let's add it in order to allow boards to specify Bluetooth in theirs device-trees, in particular this is useful for NVIDIA Tegra20 boards.

2019-12-05Bluetooth: btusb: Disable runtime suspend on Realtek devicesKai-Heng Feng
After commit 9e45524a0111 ("Bluetooth: btusb: Fix suspend issue for Realtek devices") both WiFi and Bluetooth stop working after reboot: [ 34.322617] usb 1-8: reset full-speed USB device number 3 using xhci_hcd [ 34.450401] usb 1-8: device descriptor read/64, error -71 [ 34.694375] usb 1-8: device descriptor read/64, error -71 ...

My experiment shows if the Realtek btusb device ever runtime suspends once, the entire wireless module becomes useless after reboot. So let's explicitly disable runtime suspend on Realtek btusb device for now.

Currently the error return path when the call to btusb_mtk_hci_wmt_sync fails does not free fw. Fix this by returning via the error_release_fw label that performs the free'ing.

BCM chips may require configuration of PCM to operate correctly and there is a vendor specific HCI command to do this. Add support in the hci_bcm driver to parse this from devicetree and configure the chip.

2019-11-27Bluetooth: btbcm: Support pcm configurationAbhishek Pandit-Subedi
Add BCM vendor specific command to configure PCM parameters. The new vendor opcode allows us to set the sco routing, the pcm interface rate, and a few other pcm specific options (frame sync, sync mode, and clock mode). See broadcom-bluetooth.txt in Documentation for more information about valid values for those settings. Here is an example trace where this opcode was used to configure a BCM4354: < HCI Command: Vendor (0x3f|0x001c) plen 5 01 02 00 01 01 > HCI Event: Command Complete (0x0e) plen 4 Vendor (0x3f|0x001c) ncmd 1 Status: Success (0x00) We can read back the values as well with ocf 0x001d to confirm the values that were set: $ hcitool cmd 0x3f 0x001d < HCI Command: ogf 0x3f, ocf 0x001d, plen 0 > HCI Event: 0x0e plen 9 01 1D FC 00 01 02 00 01 01 Signed-off-by: Abhishek Pandit-Subedi <abhishekpandit@chromium.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2019-11-27Bluetooth: hci_bcm: Disallow set_baudrate for BCM4354Abhishek Pandit-Subedi
Without updating the patchram, the BCM4354 does not support a higher operating speed. The normal bcm_setup follows the correct order (init_speed, patchram and then oper_speed) but the serdev driver will set the operating speed before calling the hu->setup function. Thus, for the BCM4354, don't set the operating speed before patchram.
