2024-03-06Bluetooth: hci_qca: don't use IS_ERR_OR_NULL() with gpiod_get_optional()Bartosz Golaszewski1-3/+3
The optional variants for the gpiod_get() family of functions return NULL if the GPIO in question is not associated with this device. They return ERR_PTR() on any other error. NULL descriptors are graciously handled by GPIOLIB and can be safely passed to any of the GPIO consumer interfaces as they will return 0 and act as if the function succeeded. If one is using the optional variant, then there's no point in checking for NULL.

2024-03-06Bluetooth: btnxpuart: Resolve TX timeout error in power save stress testNeeraj Sanjay Kale1-3/+21
This fixes the tx timeout issue seen while running a stress test on btnxpuart for couple of hours, such that the interval between two HCI commands coincide with the power save timeout value of 2 seconds. Test procedure using bash script: <load btnxpuart.ko> hciconfig hci0 up //Enable Power Save feature hcitool -i hci0 cmd 3f 23 02 00 00 while (true) do hciconfig hci0 leadv sleep 2 hciconfig hci0 noleadv sleep 2 done Error log, after adding few more debug prints: Bluetooth: btnxpuart_queue_skb(): 01 0A 20 01 00 Bluetooth: hci0: Set UART break: on, status=0 Bluetooth: hci0: btnxpuart_tx_wakeup() tx_work scheduled Bluetooth: hci0: btnxpuart_tx_work() dequeue: 01 0A 20 01 00 Can't set advertise mode on hci0: Connection timed out (110) Bluetooth: hci0: command 0x200a tx timeout When the power save mechanism turns on UART break, and btnxpuart_tx_work() is scheduled simultaneously, psdata->ps_state is read as PS_STATE_AWAKE, which prevents the psdata->work from being scheduled, which is responsible to turn OFF UART break. This issue is fixed by adding a ps_lock mutex around UART break on/off as well as around ps_state read/write. btnxpuart_tx_wakeup() will now read updated ps_state value. If ps_state is PS_STATE_SLEEP, it will first schedule psdata->work, and then it will reschedule itself once UART break has been turned off and ps_state is PS_STATE_AWAKE. Tested above script for 50,000 iterations and TX timeout error was not observed anymore.

2024-02-28Bluetooth: qca: Fix triggering coredump implementationZijun Hu1-5/+4
hci_coredump_qca() uses __hci_cmd_sync() to send a vendor-specific command to trigger firmware coredump, but the command does not have any event as its sync response, so it is not suitable to use __hci_cmd_sync(), fixed by using __hci_cmd_send().

BT adapter going into UNCONFIGURED state during BT turn ON when devicetree has no local-bd-address node. Bluetooth will not work out of the box on such devices, to avoid this problem, added check to set HCI_QUIRK_USE_BDADDR_PROPERTY based on local-bd-address node entry. When this quirk is not set, the public Bluetooth address read by host from controller though HCI Read BD Address command is considered as valid.

2024-02-28Bluetooth: hci_bcm4377: do not mark valid bd_addr as invalidJohan Hovold1-2/+1
A recent commit restored the original (and still documented) semantics for the HCI_QUIRK_USE_BDADDR_PROPERTY quirk so that the device address is considered invalid unless an address is provided by firmware. This specifically means that this flag must only be set for devices with invalid addresses, but the Broadcom BCM4377 driver has so far been setting this flag unconditionally. Fortunately the driver already checks for invalid addresses during setup and sets the HCI_QUIRK_INVALID_BDADDR flag, which can simply be replaced with HCI_QUIRK_USE_BDADDR_PROPERTY to indicate that the default address is invalid but can be overridden by firmware (long term, this should probably just always be allowed).

2024-01-27treewide, serdev: change receive_buf() return type to size_tFrancesco Dolcini3-6/+6
receive_buf() is called from ttyport_receive_buf() that expects values ">= 0" from serdev_controller_receive_buf(), change its return type from ssize_t to size_t. The need for this clean-up was noticed while fixing a warning, see commit 94d053942544 ("Bluetooth: btnxpuart: fix recv_buf() return value"). Changing the callback prototype to return an unsigned seems the best way to document the API and ensure that is properly used. GNSS drivers implementation of serdev receive_buf() callback return directly the return value of gnss_insert_raw(). gnss_insert_raw() returns a signed int, however this is not an issue since the value returned is always positive, because of the kfifo_in() implementation. gnss_insert_raw() could be changed to return also an unsigned, however this is not implemented here as request by the GNSS maintainer Johan Hovold.

2024-01-04USB: core: Use device_driver directly in struct usb_driver and usb_device_driverYajun Deng1-4/+2
There is usbdrv_wrap in struct usb_driver and usb_device_driver, it contains device_driver and for_devices. for_devices is used to distinguish between device drivers and interface drivers. Like the is_usb_device(), it tests the type of the device. We can test that if the probe of device_driver is equal to usb_probe_device in is_usb_device_driver(), and then the struct usbdrv_wrap is no longer needed. Clean up struct usbdrv_wrap, use device_driver directly in struct usb_driver and usb_device_driver. This makes the code cleaner.

Serdev recv_buf() callback is supposed to return the amount of bytes consumed, therefore an int in between 0 and count. Do not return a negative number in case of issue, just print an error and return count. Before this change, in case of error, the returned negative number was internally converted to 0 in ttyport_receive_buf, now when the receive buffer is corrupted we return the size of the whole received data (`count`).

2023-10-11Bluetooth: vhci: Fix race when opening vhci deviceArkadiusz Bokowy1-0/+3
When the vhci device is opened in the two-step way, i.e.: open device then write a vendor packet with requested controller type, the device shall respond with a vendor packet which includes HCI index of created interface. When the virtual HCI is created, the host sends a reset request to the controller. This request is processed by the vhci_send_frame() function. However, this request is send by a different thread, so it might happen that this HCI request will be received before the vendor response is queued in the read queue. This results in the HCI vendor response and HCI reset request inversion in the read queue which leads to improper behavior of btvirt: > dmesg [1754256.640122] Bluetooth: MGMT ver 1.22 [1754263.023806] Bluetooth: MGMT ver 1.22 [1754265.043775] Bluetooth: hci1: Opcode 0x c03 failed: -110 In order to synchronize vhci two-step open/setup process with virtual HCI initialization, this patch adds internal lock when queuing data in the vhci_send_frame() function.

Lots of cleanups in here this cycle, and some driver updates. Short summary is: - Jiri's continued work to make the tty code and apis be a bit more sane with regards to modern kernel coding style and types - cpm_uart driver updates - n_gsm updates and fixes - meson driver updates - sc16is7xx driver updates - 8250 driver updates for different hardware types - qcom-geni driver fixes - tegra serial driver change - stm32 driver updates - synclink_gt driver cleanups - tty structure size reduction All of these have been in linux-next this week with no reported issues. The last bit of cleanups from Jiri and the tty structure size reduction came in last week, a bit late but as they were just style changes and size reductions, I figured they should get into this merge cycle so that others can work on top of them with no merge conflicts" * tag 'tty-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (199 commits) tty: shrink the size of struct tty_struct by 40 bytes tty: n_tty: deduplicate copy code in n_tty_receive_buf_real_raw() tty: n_tty: extract ECHO_OP processing to a separate function tty: n_tty: unify counts to size_t tty: n_tty: use u8 for chars and flags tty: n_tty: simplify chars_in_buffer() tty: n_tty: remove unsigned char casts from character constants tty: n_tty: move newline handling to a separate function tty: n_tty: move canon handling to a separate function tty: n_tty: use MASK() for masking out size bits tty: n_tty: make n_tty_data::num_overrun unsigned tty: n_tty: use time_is_before_jiffies() in n_tty_receive_overrun() tty: n_tty: use 'num' for writes' counts tty: n_tty: use output character directly tty: n_tty: make flow of n_tty_receive_buf_common() a bool Revert "tty: serial: meson: Add a earlycon for the T7 SoC" Documentation: devices.txt: Fix minors for ttyCPM* Documentation: devices.txt: Remove ttySIOC* Documentation: devices.txt: Remove ttyIOC* serial: 8250_bcm7271: improve bcm7271 8250 port ...

2023-08-24Bluetooth: btnxpuart: Improve inband Independent Reset handlingNeeraj Sanjay Kale1-76/+96
This improves the inband IR command handling for NXP BT chipsets. When the IR vendor command is received, the driver injects a HW error event, which causes a reset sequence in hci_error_reset(). The vendor IR command is sent to the controller while hci dev is been closed, and FW is re-downloaded when nxp_setup() is called during hci_dev_do_open(). The HCI_SETUP flag is set in nxp_hw_err() to make sure that nxp_setup() is been called during hci_dev_do_open(). This also makes the nxp_setup() and power save functions more generic.

2023-08-24Bluetooth: btnxpuart: Add support for IW624 chipsetNeeraj Sanjay Kale1-7/+30
This adds support for NXP IW624 chipset in btnxpuart driver by adding FW name and bootloader signature. Based on the loader version bits 7:6 of the bootloader signature, the driver can choose between selecting secure and non-secure FW files. For cmd5 payload during FW download, this chip has addresses of few registers offset by 1, so added boot_reg_offset to handle the chip specific offset.

2023-08-24Bluetooth: btnxpuart: Remove check for CTS low after FW downloadNeeraj Sanjay Kale1-6/+1
This removes the unnecessary check for CTS low after FW download. After FW download is complete, the CTS line is already seen low. It becomes high after 2 msec, and low again after FW initialization is complete. This makes the current check for CTS low redundant. This removes the wait for CTS low section and increase delay to 1200msec instead, which is sufficiant for all NXP chipsets to initialize FW.
