a3f9f6dd04 Bluetooth: btusb: QCA: Support downloading custom-made firmwares 
There are custom-made firmwares based on board ID for a given QCA BT
chip sometimes, and they are different with existing firmwares and put
in a separate subdirectory to avoid conflict, for example:
QCA2066, as a variant of WCN6855, has firmwares under 'qca/QCA2066/'
of linux-firmware repository.

Support downloading custom-made firmwares based on a table newly added.

For GF variant of WCN6855 without board ID programmed
btusb_generate_qca_nvm_name() will chose wrong NVM
'qca/nvm_usb_00130201.bin' to download.

Fix by choosing right NVM 'qca/nvm_usb_00130201_gf.bin'.
Also simplify NVM choice logic of btusb_generate_qca_nvm_name().

This patch doesn't work quite well - It's observed that with this patch
HFP is flaky on most of the existing USB Bluetooth controllers: Intel
chips sometimes send out no packet for Transparent codec; MTK chips may
generate SCO data with a wrong handle for CVSD codec; RTK could split
the data with a wrong packet size for Transparent codec; ... etc.

7d70989fce Bluetooth: btusb: Add HCI Drv commands for configuring altsetting 
Although commit 75ddcd5ad4 ("Bluetooth: btusb: Configure altsetting
for HCI_USER_CHANNEL") has enabled the HCI_USER_CHANNEL user to send out
SCO data through USB Bluetooth chips, it's observed that with the patch
HFP is flaky on most of the existing USB Bluetooth controllers: Intel
chips sometimes send out no packet for Transparent codec; MTK chips may
generate SCO data with a wrong handle for CVSD codec; RTK could split
the data with a wrong packet size for Transparent codec; ... etc.

To address the issue above one needs to reset the altsetting back to
zero when there is no active SCO connection, which is the same as the
BlueZ behavior, and another benefit is the bus doesn't need to reserve
bandwidth when no SCO connection.

This patch adds "Supported Altsettings" and "Switch Altsetting" commands
that allow the user space program to configure the altsetting freely.

This patch is tested on ChromeOS devices. The USB Bluetooth models
(CVSD, TRANS alt3, and TRANS alt6) could pass the stress HFP test narrow
band speech and wide band speech.

04425292a6 Bluetooth: Introduce HCI Driver protocol 
Although commit 75ddcd5ad4 ("Bluetooth: btusb: Configure altsetting
for HCI_USER_CHANNEL") has enabled the HCI_USER_CHANNEL user to send out
SCO data through USB Bluetooth chips, it's observed that with the patch
HFP is flaky on most of the existing USB Bluetooth controllers: Intel

To address the issue above one needs to reset the altsetting back to
zero when there is no active SCO connection, which is the same as the
BlueZ behavior, and another benefit is the bus doesn't need to reserve
bandwidth when no SCO connection.

This patch adds the infrastructure that allow the user space program to
talk to Bluetooth drivers directly:
- Define the new packet type HCI_DRV_PKT which is specifically used for
  communication between the user space program and the Bluetooth drviers
- hci_send_frame intercepts the packets and invokes drivers' HCI Drv
  callbacks (so far only defined for btusb)
- 2 kinds of events to user space: Command Status and Command Complete,
  the former simply returns the status while the later may contain
  additional response data.

0317b033ab Bluetooth: btusb: avoid NULL pointer dereference in skb_dequeue() 
A NULL pointer dereference can occur in skb_dequeue() when processing a
QCA firmware crash dump on WCN7851 (0489:e0f3).

[ 93.672166] Bluetooth: hci0: ACL memdump size(589824)

[ 93.672475] BUG: kernel NULL pointer dereference, address: 0000000000000008
[ 93.672517] Workqueue: hci0 hci_devcd_rx [bluetooth]
[ 93.672598] RIP: 0010:skb_dequeue+0x50/0x80

The issue stems from handle_dump_pkt_qca() returning 0 even when a dump
packet is successfully processed. This is because it incorrectly
forwards the return value of hci_devcd_init() (which returns 0 on
success). As a result, the caller (btusb_recv_acl_qca() or
btusb_recv_evt_qca()) assumes the packet was not handled and passes it
to hci_recv_frame(), leading to premature kfree() of the skb.

Later, hci_devcd_rx() attempts to dequeue the same skb from the dump
queue, resulting in a NULL pointer dereference.

Fix this by:
1. Making handle_dump_pkt_qca() return 0 on success and negative errno
   on failure, consistent with kernel conventions.
2. Splitting dump packet detection into separate functions for ACL
   and event packets for better structure and readability.

This ensures dump packets are properly identified and consumed, avoiding
double handling and preventing NULL pointer access.

Once the min/max length of the commands began to be asserted, these fake

This affects various fake controllers reusing the 0A12:0001 VID/PID.

75ddcd5ad4 Bluetooth: btusb: Configure altsetting for HCI_USER_CHANNEL 
Automatically configure the altsetting for HCI_USER_CHANNEL when a SCO
is connected.

The motivation is to enable the HCI_USER_CHANNEL user to send out SCO
data through USB Bluetooth chips, which is mainly used for bidirectional
audio transfer (voice call). This was not capable because:

- Per Bluetooth Core Spec v5, Vol 4, Part B, 2.1, the corresponding
  alternate setting should be set based on the air mode in order to
  transfer SCO data, but
- The Linux Bluetooth HCI_USER_CHANNEL exposes the Bluetooth Host
  Controller Interface to the user space, which is something above the
  USB layer. The user space is not able to configure the USB alt while
  keeping the channel open.

This patch intercepts the HCI_EV_SYNC_CONN_COMPLETE packets in btusb,
extracts the air mode, and configures the alt setting in btusb.

This patch is tested on ChromeOS devices. The USB Bluetooth models
(CVSD, TRANS alt3 and alt6) could work without a customized kernel.

e9087e8288 Bluetooth: btusb: mediatek: Add locks for usb_driver_claim_interface() 
The documentation for usb_driver_claim_interface() says that "the
device lock" is needed when the function is called from places other
than probe(). This appears to be the lock for the USB interface
device. The Mediatek btusb code gets called via this path:

  Workqueue: hci0 hci_power_on [bluetooth]
  Call trace:
   usb_driver_claim_interface
   btusb_mtk_claim_iso_intf
   btusb_mtk_setup
   hci_dev_open_sync
   hci_power_on
   process_scheduled_works
   worker_thread
   kthread

With the above call trace the device lock hasn't been claimed. Claim
it.

Without this fix, we'd sometimes see the error "Failed to claim iso
interface". Sometimes we'd even see worse errors, like a NULL pointer
dereference (where `intf->dev.driver` was NULL) with a trace like:

  Call trace:
   usb_suspend_both
   usb_runtime_suspend
   __rpm_callback
   rpm_suspend
   pm_runtime_work
   process_scheduled_works

Both errors appear to be fixed with the proper locking.

The hdev->reset is never used now and the hdev->cmd_timeout actually
does reset. This patch changes the call path from
  hdev->cmd_timeout -> vendor_cmd_timeout -> btusb_reset -> hdev->reset
, to
  hdev->reset -> vendor_reset -> btusb_reset
Which makes it clear when we export the hdev->reset to a wider usage
e.g. allowing reset from sysfs.

A new machine has a Archer AX3000 / TX55e in it,
and out the box reported issues resetting hci0. It looks like
this is a MT7922 from the lspci output, so treat it as a MediaTek
device and use the proper callbacks. With that in place an xbox
controller can be used without issue as seen below:

b16b327edb Bluetooth: btusb: add sysfs attribute to control USB alt setting 
When a Bluetooth raw socket is open, the HCI event related to SCO
connection changes are not dispatched to the hci_event module, and
the underlying Bluetooth controller's USB Interface 1 will not be
updated accordingly.

This patch adds `isoc_alt` sysfs attribute, allowing user space
to update the alternate setting of the USB interface alternate
setting as needed.

61c5a3def9 Bluetooth: btmtk: adjust the position to init iso data anchor 
MediaTek iso data anchor init should be moved to where MediaTek
claims iso data interface.
If there is an unexpected BT usb disconnect during setup flow,
it will cause a NULL pointer crash issue when releasing iso
anchor since the anchor wasn't been init yet. Adjust the position
to do iso data anchor init.
