7ecacafc24 Bluetooth: btusb: Disable runtime suspend on Realtek devices
After commit 9e45524a01 ("Bluetooth: btusb: Fix suspend issue for
Realtek devices") both WiFi and Bluetooth stop working after reboot:

[   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.

5283799023 Bluetooth: btbcm: Support pcm configuration
Add BCM vendor specific command to configure PCM parameters. The new
vendor opcode allows us to set the sco routing, the pcm interface rate,
and a few other pcm specific options (frame sync, sync mode, and clock
mode). See broadcom-bluetooth.txt in Documentation for more information
about valid values for those settings.

Here is an example trace where this opcode was used to configure
a BCM4354:

        < HCI Command: Vendor (0x3f|0x001c) plen 5
                01 02 00 01 01
        > HCI Event: Command Complete (0x0e) plen 4
        Vendor (0x3f|0x001c) ncmd 1
                Status: Success (0x00)

We can read back the values as well with ocf 0x001d to confirm the
values that were set:
        $ hcitool cmd 0x3f 0x001d
        < HCI Command: ogf 0x3f, ocf 0x001d, plen 0
        > HCI Event: 0x0e plen 9

5d6f391073 Bluetooth: hci_bcm: Disallow set_baudrate for BCM4354
Without updating the patchram, the BCM4354 does not support a higher
operating speed. The normal bcm_setup follows the correct order
(init_speed, patchram and then oper_speed) but the serdev driver will
set the operating speed before calling the hu->setup function. Thus,
for the BCM4354, don't set the operating speed before patchram.

41d5b25fed Bluetooth: hci_qca: add PM support
Add PM suspend/resume callbacks for hci_qca driver.

BT host will make sure both Rx and Tx go into sleep state in
qca_suspend. Without this, Tx may still remain in awake state, which
prevents BTSOC from entering deep sleep. For example, BlueZ will send
Set Event Mask to device when suspending and this will wake the device
Rx up. However, the Tx idle timeout on the host side is 2000 ms. If the
host is suspended before its Tx idle times out, it won't send
HCI_IBS_SLEEP_IND to the device and the device Rx will remain awake.

We implement this by canceling relevant work in workqueue, sending
HCI_IBS_SLEEP_IND to the device and then waiting HCI_IBS_SLEEP_IND sent
by the device.

In order to prevent the device from being awaken again after qca_suspend
is called, we introduce QCA_SUSPEND flag. QCA_SUSPEND is set in the
beginning of qca_suspend to indicate system is suspending and that we'd
like to ignore any further wake events.

With QCA_SUSPEND and spinlock, we can avoid race condition, e.g. if
qca_enqueue acquires qca->hci_ibs_lock before qca_suspend calls
cancel_work_sync and then qca_enqueue adds a new qca->ws_awake_device
work after the previous one is cancelled.

If BTSOC wants to wake the whole system up after qca_suspend is called,
it will keep sending HCI_IBS_WAKE_IND and uart driver will take care of
waking the system. For example, uart driver will reconfigure its Rx pin
to a normal GPIO pin and enable irq wake on that pin when suspending.
Once host detects Rx falling, the system will begin resuming. Then, the
BT host clears QCA_SUSPEND flag in qca_resume and begins dealing with
normal HCI packets. By doing so, only a few HCI_IBS_WAKE_IND packets are
lost and there is no data packet loss.

The frame reassembly errors were root caused to a transient gpio issue.
The missing response was root caused to an issue with properly managing

hci_qca and eliminates the need for the 50ms delay, so remove it.

These printing macros already add a trailing newline, so drop these
unnecessary additional newlines.

the rtl: or RTL: prefix in the string is pointless. The rtl_dev_* macros

010376ab7f Bluetooth: hci_qca: wait for Pre shutdown complete event before sending the Power off pulse
When SoC receives pre shut down command, it share the same
with other COEX shared clients. So SoC needs a short time
after sending VS pre shutdown command before turning off
the regulators and sending the power off pulse. Along with
short delay, needs to wait for command complete event for
Pre shutdown VS command

16946de590 bluetooth: hci_bcm: Give more time to come out of reset
Some supported devices need more time to come out of reset (eg.
BCM4345C5 in AP6256).

I don't have/found a datasheet, so the value was arrive at
experimentally with the Oprange Pi 3 board. Without increased delay,
I got intermittent failures during probe. This is a Bluetooth 5.0
device, so maybe that's why it takes longer to initialize than the
others.

2edc9c5cca Bluetooth: hci_qca: Make structure qca_proto constant
Static structure qca_proto, of type hci_uart_proto, is used four times:
as the last argument in function hci_uart_register_device(), and as the
only argument to functions hci_uart_register_proto() and
hci_uart_unregister_proto(). In all three of these functions, the
parameter corresponding to qca_proto is declared as constant. Therefore,
make qca_proto itself constant as well in order to protect it from
unintended modification.
Issue found with Coccinelle.

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.
