[ 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):```

commit d73e172816652772114827abaa2dbc053eecbbd7 upstream.
John Stultz reports a boot time crash with the HiKey board (which uses
hci_serdev) occurring in hci_uart_tx_wakeup(). That function is
contained in hci_ldisc.c, but also called from the newer hci_serdev.c.
It acquires the proto_lock in struct hci_uart and it turns out that we
forgot to init the lock in the serdev code path, thus causing the crash.John bisected the crash to commit 67d2f8781b9f ("Bluetooth: hci_ldisc:
Allow sleeping while proto locks are held"), but the issue was present
before and the commit merely exposed it. (Perhaps by luck, the crash
did not occur with rwlocks.)Init the proto_lock in the serdev code path to avoid the oops.

commit 67d2f8781b9f00d1089aafcfa3dc09fcd0f343e2 upstream.
Commit dec2c92880cc5435381d50e3045ef018a762a917 ("Bluetooth: hci_ldisc:
Use rwlocking to avoid closing proto races") introduced locks in
hci_ldisc that are held while calling the proto functions. These locks
are rwlock's, and hence do not allow sleeping while they are held.
However, the proto functions that hci_bcm registers use mutexes and
hence need to be able to sleep.In more detail: hci_uart_tty_receive() and hci_uart_dequeue() both
acquire the rwlock, after which they call proto->recv() and
proto->dequeue(), respectively. In the case of hci_bcm these point to
bcm_recv() and bcm_dequeue(). The latter both acquire the
bcm_device_lock, which is a mutex, so doing so results in a call to
might_sleep(). But since we're holding a rwlock in hci_ldisc, that
results in the following BUG (this for the dequeue case - a similar
one for the receive case is omitted for brevity):BUG: sleeping function called from invalid context at kernel/locking/mutex.c

there that might sleep. Therefore this replaces the rwlock's in
hci_ldisc with rw_semaphore's (which allow sleeping). This is a safer
approach anyway as it reduces the restrictions on the proto callbacks.
Also, because acquiring write-lock is very rare compared to acquiring
the read-lock, the percpu variant of rw_semaphore is used.Lastly, because hci_uart_tx_wakeup() may be called from an IRQ context,
we can't block (sleep) while trying acquire the read lock there, so we
use the trylock variant.Signed-off-by: Ronald Tschalär

commit fc54910280eb38bde923cdf0898e74687d8e6989 upstream.
Jeremy Cline correctly points out in rhbz#1514836 that a device where the
QCA rome chipset needs the USB_QUIRK_RESET_RESUME quirk, may also ship
with a different wifi/bt chipset in some configurations.If that is the case then we are needlessly penalizing those other chipsets
with a reset-resume quirk, typically causing 0.4W extra power use because
this disables runtime-pm.This commit moves the DMI table check to a btusb_check_needs_reset_resume()
helper (so that we can easily also call it for other chipsets) and calls
this new helper only for QCA_ROME chipsets for now.BugLink: https://bugzilla.redhat.com/show_bug.cgi?id=1514836

commit bb5208b314c5127b716b2ee4f55803a8bb73b750 upstream.
Older devices with a serdev attached bcm bt hci, use an Interrupt ACPI
resource to describe the IRQ (rather then a GpioInt resource).These device seem to all claim the IRQ is active-high and seem to all need
a DMI quirk to treat it as active-low. Instead simply always assume that
Interrupt resource specified IRQs are always active-low.This fixes the bt device not being able to wake the host from runtime-
suspend on the: Asus T100TAM, Asus T200TA, Lenovo Yoga2 and the Toshiba
Encore, without the need to add 4 new DMI quirks for these models.This also allows us to remove 2 DMI quirks for the Asus T100TA and Asus
T100CHI series. Likely the 2 remaining quirks can also be removed but I
could not find a DSDT of these devices to verify this.Cc: stable@vger.kernel.org

[ Upstream commit 0a03f98b98c201191e3ba15a0e33f46d8660e1fd ]
This patch adds the 04ca:3015 (from a QCA9377 board) Bluetooth device
to the btusb blacklist and makes the kernel use the btqca module
instead of btusb. The patch is necessary because, without it the
04ca:3015 device defaults to using the btusb driver, which makes the
WIFI side of the QCA9377 board unusable (obtains 0 MBps in speedtest,
when the 04ca:3015 bluetooth is used with an audio headset)./sys/kernel/debug/usb/devices:

commit f44cb4b19ed40b655c2d422c9021ab2c2625adb6 upstream.
The Atheros 1525/QCA6174 BT doesn't seem working properly on the
recent kernels, as it tries to load a wrong firmware
ar3k/AthrBT_0x00000200.dfu and it fails.This seems to have been a problem for some time, and the known
workaround is to apply BTUSB_QCA_ROM quirk instead of BTUSB_ATH3012.The device in question is:

commit f0e8c61110c2c85903b136ba070daf643a8b6842 upstream.
Commit 1fdb92697469 ("Bluetooth: btusb: Use DMI matching for QCA
reset_resume quirking"), added the Lenovo Yoga 920 to the
btusb_needs_reset_resume_table.Testing has shown that this is a false positive and the problems where
caused by issues with the initial fix: commit fd865802c66b ("Bluetooth:
btusb: fix QCA Rome suspend/resume"), which has already been reverted.So the QCA Rome BT in the Yoga 920 does not need a reset-resume quirk at
all and this commit removes it from the btusb_needs_reset_resume_table.Note that after this commit the btusb_needs_reset_resume_table is now
empty. It is kept around on purpose, since this whole series of commits
started for a reason and there are actually broken platforms around,
which need to be added to it.BugLink: https://bugzilla.redhat.com/show_bug.cgi?id=1514836

only if the setup_rome method returns succes and run in 'standard'

commit 1fdb926974695d3dbc05a429bafa266fdd16510e upstream.
Commit 61f5acea8737 ("Bluetooth: btusb: Restore QCA Rome suspend/resume fix
with a "rewritten" version") applied the USB_QUIRK_RESET_RESUME to all QCA
USB Bluetooth modules. But it turns out that the resume problems are not
caused by the QCA Rome chipset, on most platforms it resumes fine. The
resume problems are actually a platform problem (likely the platform
cutting all power when suspended).The USB_QUIRK_RESET_RESUME quirk also disables runtime suspend, so by
matching on usb-ids, we're causing all boards with these chips to use extra
power, to fix resume problems which only happen on some boards.This commit fixes this by applying the quirk based on DMI matching instead
of on usb-ids, so that we match the platform and not the chipset.Here is the /sys/kernel/debug/usb/devices for the Bluetooth module:

commit 05e89fb576f580ac95e7a5d00bdb34830b09671a upstream.
It is no longer possible to build BT_HCIUART into the kernel
when SERIAL_DEV_BUS is a loadable module, even if none of the
SERIAL_DEV_BUS based implementations are selected:drivers/bluetooth/hci_ldisc.o: In function `hci_uart_set_flow_control':

hci_ldisc.c:(.text+0xb5c): undefined reference to `serdev_device_set_tiocm'This adds a dependency to avoid the broken configuration.

commit 61f5acea8737d9b717fcc22bb6679924f3c82b98 upstream.
Commit 7d06d5895c15 ("Revert "Bluetooth: btusb: fix QCA...suspend/resume"")
removed the setting of the BTUSB_RESET_RESUME quirk for QCA Rome devices,
instead favoring adding USB_QUIRK_RESET_RESUME quirks in usb/core/quirks.c.This was done because the DIY BTUSB_RESET_RESUME reset-resume handling
has several issues (see the original commit message). An added advantage
of moving over to the USB-core reset-resume handling is that it also
disables autosuspend for these devices, which is similarly broken on these.But there are 2 issues with this approach:
1) It leaves the broken DIY BTUSB_RESET_RESUME code in place for Realtek
devices.
2) Sofar only 2 of the 10 QCA devices known to the btusb code have been
added to usb/core/quirks.c and if we fix the Realtek case the same way
we need to add an additional 14 entries. So in essence we need to
duplicate a large part of the usb_device_id table in btusb.c in
usb/core/quirks.c and manually keep them in sync.This commit instead restores setting a reset-resume quirk for QCA devices
in the btusb.c code, avoiding the duplicate usb_device_id table problem.This commit avoids the problems with the original DIY BTUSB_RESET_RESUME
code by simply setting the USB_QUIRK_RESET_RESUME quirk directly on the
usb_device.This commit also moves the BTUSB_REALTEK case over to directly setting the
USB_QUIRK_RESET_RESUME on the usb_device and removes the now unused
BTUSB_RESET_RESUME code.BugLink: https://bugzilla.redhat.com/show_bug.cgi?id=1514836

commit 7d06d5895c159f64c46560dc258e553ad8670fe0 upstream.
This reverts commit fd865802c66bc451dc515ed89360f84376ce1a56.
This commit causes a regression on some QCA ROME chips. The USB device
reset happens in btusb_open(), hence firmware loading gets interrupted.Furthermore, this commit stops working after commit
("a0085f2510e8976614ad8f766b209448b385492f Bluetooth: btusb: driver to
enable the usb-wakeup feature"). Reset-resume quirk only gets enabled in
btusb_suspend() when it's not a wakeup source.If we really want to reset the USB device, we need to do it before
btusb_open(). Let's handle it in drivers/usb/core/quirks.c.Cc: Leif Liddy

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.Signed-off-by: Hans de Goede

[ Upstream commit 227630cccdbb8f8a1b24ac26517b75079c9a69c9 ]
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.Signed-off-by: Hans de Goede

commit 6e518111060c2290427d79c43d4add9600ad852b upstream.
This patch implements the hdev setup function since wcnss-bt does not have
persistent memory to store an allocated BD address. The device is therefore
marked as unconfigured if no BD address has been previously retrieved.Signed-off-by: Loic Poulain

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.By default all files without license information are under the default
license of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if

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

Not all Broadcom controller support the 4Mbps operational speed on UART
devices. This is because the UART clock setting changes might not be
supported.< HCI Command: Broadcom Write UART Clock Setting (0x3f|0x0045) plen 1

> HCI Event: Command Complete (0x0e) plen 4
Broadcom Write UART Clock Setting (0x3f|0x0045) ncmd 1
Status: Unknown HCI Command (0x01)To support any operational speed higher than 3Mbps, support for this
command is required. 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.This patch assigns the 4Mbps opertional speed only for devices
discovered through ACPI and leave all others at the default 115200.Signed-off-by: Marcel Holtmann

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.Signed-off-by: Sukumar Ghorai

The GPD Pocket is shipping with a BCM2045 USB HCI with its vendor and
product information set to 0000:0000 and also has its interface class
set to 255 (Vendor Specific Class). Luckily it does advertise usable
