Sukumar Ghorai 905d7b1311 Bluetooth: btusb: print Intel fw build version in power-on boot
To determine the build version of Bluetooth firmware to ensure reported
issue related to a particular release. This is very helpful for every fw
downloaded to BT controller and issue reported from field test.

Alain Michaud 00bce3fb06 Bluetooth: Enable erroneous data reporting if WBS is supported
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.

Alain Michaud 3e4e3f73b9 Bluetooth: btusb: Add flag to define wideband speech capability
This change adds a new flag to define a controller's wideband speech
capability.  This is required since no reliable over HCI mechanism
exists to query the controller and driver's compatibility with
wideband speech.

[   44.599493] rtw_pci 0000:02:00.0: failed to leave idle state

That commit removed USB_QUIRK_RESET_RESUME, which not only resets the USB
device after resume, it also prevents the device from being runtime
suspended by USB core. 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.

Alex Lu 9e45524a01 Bluetooth: btusb: Fix suspend issue for Realtek devices
From the perspective of controller, global suspend means there is no
SET_FEATURE (DEVICE_REMOTE_WAKEUP) and controller would drop the
firmware. It would consume less power. So we should not send this kind
of SET_FEATURE when host goes to suspend state.
Otherwise, when making device enter selective suspend, host should send
SET_FEATURE to make sure the firmware remains.

Mario Limonciello 1ffdb51f28 Revert "Bluetooth: btusb: driver to enable the usb-wakeup feature"
This reverts commit a0085f2510.

This commit has caused regressions in notebooks that support suspend
to idle such as the XPS 9360, XPS 9370 and XPS 9380.

These notebooks will wakeup from suspend to idle from an unsolicited
advertising packet from an unpaired BLE device.

In a bug report it was sugggested that this is caused by a generic
lack of LE privacy support.  Revert this commit until that behavior
can be avoided by the kernel.

Jian-Hong Pan 7af3f558ac Bluetooth: btrtl: HCI reset on close for Realtek BT chip
Realtek RTL8822BE BT chip on ASUS X420FA cannot be turned on correctly
after on-off several times. Bluetooth daemon sets BT mode failed when
this issue happens. Scanning must be active while turning off for this
bug to be hit.

bluetoothd[1576]: Failed to set mode: Failed (0x03)

If BT is turned off, then turned on again, it works correctly again.

According to the vendor driver, the HCI_QUIRK_RESET_ON_CLOSE flag is set
during probing. So, this patch makes Realtek's BT reset on close to fix
this issue.

Brian Norris 771acc7e4a Bluetooth: btusb: request wake pin with NOAUTOEN
Badly-designed systems might have (for example) active-high wake pins
that default to high (e.g., because of external pull ups) until they
have an active firmware which starts driving it low.  This can cause an
interrupt storm in the time between request_irq() and disable_irq().

We don't support shared interrupts here, so let's just pre-configure the
interrupt to avoid auto-enabling it.

Raghuram Hegde 017a01ccfb Bluetooth: btusb: Add shutdown routine for BTUSB_INTEL_NEW devices
If BT operations (BREDR inquiry/LE scan) were triggered
through the stack, followed by BT turn off through
'hciconfig hci0 down', the controller would still be active
and consume power.
Also, there is a possibility that a race condition/
synchronization issue might arise on the subsequent BT turn
on, as the controller might try to push the
events that were queued up before processing the HCI Reset
command.

btusb_shutdown_intel_new routine shall reset the controller
and stop all BT operation.
Advantages:
	1. Power save on the platform
	2. Host and controller will be in Sync.

inject_cmd_complete() is only called by btusb_send_frame_intel(),
which is set to hdev->send, and hdev->send() is never
called in atomic context.

inject_cmd_complete() calls bt_skb_alloc() with GFP_ATOMIC,
which is not necessary.
GFP_ATOMIC can be replaced with GFP_KERNEL.

This is found by a static analysis tool named DCNS written by myself.

The USB completion callback does not disable interrupts while acquiring
the ->lock. We want to remove the local_irq_disable() invocation from
__usb_hcd_giveback_urb() and therefore it is required for the callback
handler to disable the interrupts while acquiring the lock.
The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave variant of the locking primitives.

Hans de Goede 939bc6c59e Bluetooth: btusb: Add Dell Inspiron 5565 to btusb_needs_reset_resume_table
The Dell Inspiron 5565 uses a QCA Rome chip which needs to be reset
(and have its firmware reloaded) for bluetooth to work after
suspend/resume.

Takashi Iwai 803cdb8ce5 Bluetooth: btusb: Apply QCA Rome patches for some ATH3012 models
In commit f44cb4b19e ("Bluetooth: btusb: Fix quirk for Atheros
1525/QCA6174") we tried to address the non-working Atheros BT devices
by changing the quirk from BTUSB_ATH3012 to BTUSB_QCA_ROME.  This made
such devices working while it turned out to break other existing chips
with the very same USB ID, hence it was reverted afterwards.

This is another attempt to tackle the issue.  The essential point to
use BTUSB_QCA_ROME is to apply the btusb_setup_qca() and do RAM-
patching.  And the previous attempt failed because btusb_setup_qca()
returns -ENODEV if the ROM version doesn't match with the expected
ones.  For some devices that have already the "correct" ROM versions,
we may just skip the setup procedure and continue the rest.

So, the first fix we'll need is to add a check of the ROM version in
the function to skip the setup if the ROM version looks already sane,
so that it can be applied for all ath devices.

However, the world is a bit more complex than that simple solution.
Since BTUSB_ATH3012 quirk checks the bcdDevice and bails out when it's
0x0001 at the beginning of probing, so the device probe always aborts
here.

In this patch, we add another check of ROM version again, and if the
device needs patching, the probe continues.  For that, a slight
refactoring of btusb_qca_send_vendor_req() was required so that the
probe function can pass usb_device pointer directly before allocating
hci_dev stuff.

Hans de Goede fc54910280 Bluetooth: btusb: Only check needs_reset_resume DMI table for QCA rome chipsets
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.

So lets revert it for now and try to find another solution for
devices which need the modified quirk.
