Sean Wang 6ac034a76a Bluetooth: btmtkuart: fix the conflict between mtk and msft vendor event
There is a conflict between MediaTek wmt event and msft vendor extension
logic in the core layer since 145373cb1b ("Bluetooth: Add framework for
Microsoft vendor extension") was introduced because we changed the type of
mediatek wmt event to the type of msft vendor event in the driver.

But the purpose we reported mediatek event to the core layer is for the
diagnostic purpose with that we are able to see the full packet trace via
monitoring socket with btmon. Thus, it is harmless we keep the original
type of mediatek vendor event here to avoid breaking the msft extension
function especially they can be supported by Mediatek future devices.

Vyacheslav Bocharov adce573b92 Bluetooth: hci_h5: Add power reset via gpio in h5_btrtl_open
Add power reset for bluetooth via enable-gpios in h5_btrtl_open function.

While testing the RTL8822CS SDIO WiFi/BT adapter, it was found that in
some cases the kernel could not initialize BT firmware. However,
manually resetting the adapter via gpio (off/on sequence) allows it to
start correctly.
Apparently, when the system starts, the adapter is in an undefined state
(including unknown gpio state after starting uboot). A forced reset helps
to initialize the adapter in most cases. It has been found experimentally
that 100 ms is sufficient for a reset.

Sean Wang db3f1f9b5d Bluetooth: btmtksdio: mask out interrupt status
Currently, there is a loop in btmtksdio_txrx_work() which iteratively
executes until the variable int_status is zero.

But the variable int_status should be masked out with the actual interrupt
sources (MTK_REG_CHISR bit 0-15) before we check the loop condition.
Otherwise, RX_PKT_LEN (MTK_REG_CHISR bit 16-31) which is read-only and
unclearable would cause the loop to get stuck on some chipsets like
MT7663s.

Mark Chen 01ecc177b7 Bluetooth: mt7921s: fix btmtksdio_[drv|fw]_pmctrl()
According to the firmware behavior (even the oldest one in linux-firmware)

If the firmware is downloaded, MT7921S must rely on the additional mailbox
mechanism that resides in firmware to check if the device is the right
state for btmtksdio_mcu_[drv|fw]_pmctrl(). Otherwise, we still apply the
old way for that.

That is a necessary patch before we enable runtime pm for mt7921s as
default.

kvartet reported, that hci_uart_tx_wakeup() uses uninitialized rwsem.
The problem was in wrong place for percpu_init_rwsem() call.

hci_uart_proto::open() may register a timer whose callback may call
hci_uart_tx_wakeup(). There is a chance, that hci_uart_register_device()
thread won't be fast enough to call percpu_init_rwsem().

Fix it my moving percpu_init_rwsem() call before p->open().

INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?
turning off the locking correctness validator.

Mark Chen 191c872308 Bluetooth: mt7921s: Enable SCO over I2S
The driver has to issue the specific command to enable Bluetooth SCO over
the I2S/PCM interface on mt7921s, that is supported since the firmware
with version 20211222191101 was added, and the patch would not cause any
harm even when the old firmware is applied.

The SCO profile with the patch was tested by setting up a VOIP application,
connected to HFP device, checked telephony function can work normally.

Mark Chen ce64b3e949 Bluetooth: mt7921s: Support wake on bluetooth
Enable wake on bluetooth on mt7921s that can be supported since the
firmware with version 20211129211059 was added, and the patch would
not cause any harm even when the old firmware is applied.

The patch was tested by setting up an HID or HOGP profile to connect a
Bluetooth keyboard and mouse, then putting the system to suspend, then
trying to wake up the system by moving the Bluetooth keyboard or mouse,
and then checking if the system can wake up and be brought back to
the normal state.

Tedd Ho-Jeong An 95655456e7 Bluetooth: btintel: Fix broken LED quirk for legacy ROM devices
This patch fixes the broken LED quirk for Intel legacy ROM devices.
To fix the LED issue that doesn't turn off immediately, the host sends
the SW RFKILL command while shutting down the interface and it puts the
devices in SW RFKILL state.

Once the device is in SW RFKILL state, it can only accept HCI_Reset to
exit from the SW RFKILL state. This patch checks the quirk for broken
LED and sends the HCI_Reset before sending the HCI_Intel_Read_Version
command.

The affected legacy ROM devices are

 - 8087:0a2a
 - 8087:0aa7

Jiasheng Jiang b38cd3b42f Bluetooth: hci_bcm: Check for error irq
For the possible failure of the platform_get_irq(), the returned irq
could be error number and will finally cause the failure of the
request_irq().
Consider that platform_get_irq() can now in certain cases return
-EPROBE_DEFER, and the consequences of letting request_irq() effectively
convert that into -EINVAL, even at probe time rather than later on.
So it might be better to check just now.

Jakub Kicinski b6459415b3 net: Don't include filter.h from net/sock.h
sock.h is pretty heavily used (5k objects rebuilt on x86 after
it's touched). We can drop the include of filter.h from it and
add a forward declaration of struct sk_filter instead.
This decreases the number of rebuilt objects when bpf.h
is touched from ~5k to ~1k.

There's a lot of missing includes this was masking. Primarily
in networking tho, this time.

Luiz Augusto von Dentz 800fe5ec30 Bluetooth: btusb: Add support for queuing during polling interval
This makes btusb to queue ACL and events during a polling interval
by using of a delayed work, with the interval working as a time window
where frames received from different endpoints are considered to be
arrived at same time and then attempt to resolve potential conflics by
processing the events ahead of ACL packets.

It worth noting though that priorizing events over ACL data may result
in inverting the order compared to how they appeared over the air, for
instance there may be packets received before a disconnect event that
will be discarded and unencrypted packets received before encryption
change which would considered encrypted, because of these potential
changes on the order the support for queuing during the polling
interval is not enabled by default so it requires setting
force_poll_sync debugfs while the adapter is down.

btmtksdio belongs to WIFI/BT combo chip that would serve two radios in one
sdio_irq so that we have to move interrupt service to worker to ensure ISR
as short as possible.

The worker would serve the both Tx and Rx in a batch to effectively reduce
many interrupts to the host and to avoid excessive sdio lock contention
between various context (even from WiFi driver) and help to be more
efficient to complete command/event transation.
