By default, WCN3991 sent debug packets to HOST via ACL packet
with header 0xDC2E. This logging is not required on commercial
devices. With this patch SoC logging is disabled post fw
download.

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

commit 32646db8cc28 ("Bluetooth: btqca: inject command complete event
during fw download") added qca_inject_cmd_complete_event() for certain
qualcomm chips. However, qca_download_firmware() will return without
calling release_firmware() in this case.
This leads to a memory leak like the following found by kmemleak:

The opcode of the command injected by commit 32646db8cc28 ("Bluetooth:
btqca: inject command complete event during fw download") uses the CPU
byte format, however it should always be little endian. In practice it
shouldn't really matter, since all we need is an opcode != 0, but still
let's do things correctly and keep sparse happy.

On WCN3990 downloading the NVM sometimes fails with a "TLV response
size mismatch" error:
[ 174.949955] Bluetooth: btqca.c:qca_download_firmware() hci0: QCA Downloading qca/crnv21.bin
[ 174.958718] Bluetooth: btqca.c:qca_tlv_send_segment() hci0: QCA TLV response size mismatch
It seems the controller needs a short time after downloading the
firmware before it is ready for the NVM. A delay as short as 1 ms
seems sufficient, make it 10 ms just in case. No event is received
during the delay, hence we don't just silently drop an extra event.

or I2S, Setting Tx power, etc.) via this file. This patch will allow

Latest qualcomm chips are not sending an command complete event for
every firmware packet sent to chip. They only respond with a vendor
specific event for the last firmware packet. This optimization will
decrease the BT ON time. Due to this we are seeing a timeout error
message logs on the console during firmware download. Now we are
injecting a command complete event once we receive an vendor specific
event for the last RAM firmware packet.

Redefinition of qca_uart_setup will help future Qualcomm Bluetooth
SoC, to use the same function instead of duplicating the function.
Added new arguments soc_type and soc_ver to the functions.
These arguments will help to decide type of firmware files
to be loaded into Bluetooth chip.
soc_type holds the Bluetooth chip connected to APPS processor.
soc_ver holds the Bluetooth chip version.

Some of the QCA BTSoC ROME functions, are used for different versions
or different make of BTSoC's. Instead of duplicating the same functions
for new chip, update names of the functions that are used for both
chips to keep this generic and would help in future when we would have
new BT SoC. To have generic text in logs updated from ROME to QCA where
ever possible. This avoids confusion to user, when using the future
Qualcomm Bluetooth SoC's. Updated BT_DBG, BT_ERR and BT_INFO with
bt_dev_dbg, bt_dev_err and bt_dev_info where ever applicable.

This patch adds rampatch download compatibility for ROME >= 3.2.
Starting with ROME 3.2, the 'download mode' field of the rampatch
header indicates if the controller acknowledges (or not) the received
rampatch segments. If not, we need to send all the segments without
expecting any event from the controller (except for the last segment).
Goal is (I assume) to speed-up rampatch download.
This fixes BT on Dragonboard-600c P2 which includes the following BT
controller:
