2017-10-14Bluetooth: mark expected switch fall-throughsGustavo A. R. Silva2-2/+2
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. In this particular case, notice that I replaced the "deliberate fall-through..." comment with a "fall through" comment, which is what GCC is expecting to find. Signed-off-by: Gustavo A. R.

2017-10-14Revert "Bluetooth: btusb: Add workaround for Broadcom devices without product id"Hans de Goede1-18/+0
Commit 9834e586fa66 ("Bluetooth: btusb: Add workaround for Broadcom devices without product id") was added to deal with the BT part of the BCM4356A2 on GPD pocket laptops having an usb vid:pid of 0000:0000. After another commit to add support for the BCM UART connected BT ACPI-id BCM2E7E used on the GPD win, it turns out that the BT on the GPD pocket is connected via both USB and UART. Adding support for the BCM2E7E ACPI-id causes it to switch to UART mode. The Windows shipped with the device is using it in UART mode and the presence of the BCM2E7E ACPI-id combined with the all 0 USB vid:pid indicates that the BT part was never meant to be used in USB mode. With the recent patches to use serdev device enumeration / instantiation for UART attached ACPI enumerated BT devices, everything work OOTB in UART mode and the workaround for the all 0 USB vid:pid is no longer needed. This reverts commit 9834e586fa ("Bluetooth: btusb: Add workaround for Broadcom devices without product id").

2017-10-10Bluetooth: avoid silent hci_bcm ACPI PM regressionJohan Hovold1-0/+1
The hci_bcm platform-device hack which was used to implement power management for ACPI devices is being replaced by a serial-device-bus implementation. Unfortunately, when the corresponding change to the ACPI code lands (a change that will stop enumerating and registering the serial-device-node child as a platform device) PM will break silently unless serdev TTY-port controller support has been enabled. Specifically, hciattach (btattach) would still succeed, but power management would no longer work. Although this is strictly a runtime dependency, let's make the driver depend on SERIAL_DEV_CTRL_TTYPORT, which is the particular serdev controller implementation used by the ACPI devices currently managed by this driver, to avoid breaking PM without anyone noticing. Note that the driver already has a (build-time) dependency on the serdev bus code. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

The ACPI subsys is going to move over to instantiating ACPI enumerated HCIs as serdevs, rather then as platform devices. So we need to make bcm_acpi_probe() suitable for use on non platform- devices too, which means that we cannot rely on platform_get_irq() getting called.

2017-10-06Bluetooth: hci_bcm: Store device pointer instead of platform_device pointerHans de Goede1-38/+35
The ACPI subsys is going to move over to instantiating ACPI enumerated HCIs as serdevs, rather then as platform devices. This means that the serdev driver paths of hci_bcm.c also need to start supporting (runtime)pm through GPIOs and a host-wake IRQ. The hci_bcm code is already mostly independent of how the HCI gets instantiated, but even though the code only cares about pdev->dev, it was storing pdev itself in struct bcm_device. This commit stores pdev->dev rather then pdev in struct bcm_device, this is a preparation patch for adding (runtime)pm support to the serdev path.

Most of the code in bcm_platform_probe is actually not platform specific and will work with any struct device passed to it, the one platform specific call in bcm_platform_probe is platform_get_irq.

2017-10-06Bluetooth: hci_bcm: Fix setting of irq trigger typeHans de Goede1-13/+10
This commit fixes 2 issues with host-wake irq trigger type handling in hci_bcm: 1) bcm_setup_sleep sets sleep_params.host_wake_active based on bcm_device.irq_polarity, but bcm_request_irq was always requesting IRQF_TRIGGER_RISING as trigger type independent of irq_polarity. This was a problem when the irq is described as a GpioInt rather then an Interrupt in the DSDT as for GpioInt-s the value passed to request_irq is honored. This commit fixes this by requesting the correct trigger type depending on bcm_device.irq_polarity. 2) bcm_device.irq_polarity was used to directly store an ACPI polarity value (ACPI_ACTIVE_*). This is undesirable because hci_bcm is also used with device-tree and checking for something like ACPI_ACTIVE_LOW in a non ACPI specific function like bcm_request_irq feels wrong. This commit fixes this by renaming irq_polarity to irq_active_low and changing its type to a bool.

2017-08-17Bluetooth: hci_bcm: Handle empty packet after firmware loadingMarcel Holtmann1-0/+11
The Broadcom controller on the Raspberry Pi3 sends an empty packet with packet type 0x00 after launching the firmware. This will cause logging of errors. Bluetooth: hci0: Frame reassembly failed (-84) Since this seems to be an intented behaviour of the controller, handle it gracefully by parsing that empty packet with packet type 0x00 and then just simply report it as diagnostic packet. With that change no errors are logging and the packet itself is actually recorded in the Bluetooth monitor traces. < HCI Command: Broadcom Launch RAM (0x3f|0x004e) plen 4 Address: 0xffffffff > HCI Event: Command Complete (0x0e) plen 4 Broadcom Launch RAM (0x3f|0x004e) ncmd 1 Status: Success (0x00) = Vendor Diagnostic (len 0) < HCI Command: Broadcom Update UART Baud Rate (0x3f|0x0018) plen 6 00 00 00 10 0e 00 ...... > HCI Event: Command Complete (0x0e) plen 4 Broadcom Update UART Baud Rate (0x3f|0x0018) ncmd 1 Status: Success (0x00) < HCI Command: Reset (0x03|0x0003) plen 0 > HCI Event: Command Complete (0x0e) plen 4 Reset (0x03|0x0003) ncmd 1 Status: Success (0x00) Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

Not all Broadcom controller support the 4Mbps operational speed on UART devices.

With that respect it is better to not enforce any operational speed by default. Only when its support is known, then allow for higher operational speed.

BT-Controller connected as platform non-root-hub device and usb-driver initialize such device with wakeup disabled, Ref. usb_new_device(). At present wakeup-capability get enabled by hid-input device from usb function driver(e.g. BT HID device) at runtime. Again some functional driver does not set usb-wakeup capability(e.g LE HID device implement as HID-over-GATT), and can't wakeup the host on USB. Most of the device operation (such as mass storage) initiated from host (except HID) and USB wakeup aligned with host resume procedure. For BT device, usb-wakeup capability need to enable form btusc driver as a generic solution for multiple profile use case and required for USB remote wakeup (in-bus wakeup) while host is suspended. Also usb-wakeup feature need to enable/disable with HCI interface up and down.

Keep power LED on during activity. LED timer races with power LED disabling in hci_close(), resulting in power LED left on after closing. Stop LED timer before disabling power LED. BTW. On cards without an activity LED, the behavior is a bit weird: The LED is on after hci_open() but only until the first data transfer. Then it's off in idle and on during activity.

2017-08-07Bluetooth: bluecard: Always enable LEDs (fix for Anycom CF-300)Ondrej Zary1-18/+6
Anycom CF-300 (HP C8249A) has both power and activity LEDs. However the id read in bluecard_open() is 0x73 so the driver does not enable the LEDs. Remove the CARD_HAS_PCCARD_ID check to enable LEDs.

2017-07-20Bluetooth: btwilink: remove unnecessary static in bt_ti_probe()Gustavo A. R. Silva1-1/+1
Remove unnecessary static on local variable hst. Such variable is initialized before being used, on every execution path throughout the function. The static has no benefit and, removing it reduces the object file size. This issue was detected using Coccinelle and the following semantic patch: @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; In the following log you can see the difference in the object file size. This log is the output of the size command, before and after the code change: before: text data bss dec hex filename 4029 2528 128 6685 1a1d drivers/bluetooth/btwilink.o after: text data bss dec hex filename 4007 2472 64 6543 198f drivers/bluetooth/btwilink.o Signed-off-by: Gustavo A.
