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.

The Realtek RTL8723BS and RTL8723DS chipsets are SDIO wifi chips. They
also contain a Bluetooth module which is connected via UART to the host.
Realtek's userspace initialization tool (rtk_hciattach) differentiates
these two via the HCI version and revision returned by the
HCI_OP_READ_LOCAL_VERSION command.
Additionally we apply these checks only the for UART devices. Everything
else is assumed to be a "RTL8723B" which was originally supported by the
driver (communicating via USB).

The UART settings are embedded in the config blob. This has to be parsed
to successfully initialize the Bluetooth part of the RTL8723BS (which is
an SDIO chip, but the Bluetooth part is connected via UART).
The Realtek "rtl8723bs_bt" and "rtl8723ds_bt" userspace Bluetooth UART
initialization tools (rtk_hciattach) use the following sequence:
- send H5 sync pattern (already supported by hci_h5)
- get LMP version (already supported by btrtl)
- get ROM version (already supported by btrtl)
- load the firmware and config for the current chipset (already
supported by btrtl)
- read UART settings from the config blob (part of this patch)
- send UART settings via a vendor command to the device (which changes
the baudrate of the device and enables or disables flow control
depending on the config)
- change the baudrate and flow control settings on the host
- send the firmware and config blob to the device (already supported by
btrtl)
Sending the last firmware and config blob download command
(rtl_download_cmd) fails if the UART settings are not updated
beforehand. This is presumably because the device applies the config
right after the firmware and config blob download - which means that at
this point the host is using different UART settings than the device
(which will obviously result in non-working communication).

This prepares the btrtl code so it can be used to initialize Bluetooth
modules connected via UART (these are found for example on the RTL8723BS
and RTL8723DS SDIO chips, which come with an embedded UART Bluetooth
module).
The Realtek "rtl8723bs_bt" and "rtl8723ds_bt" userspace Bluetooth UART
initialization tools (rtk_hciattach) use the following sequence:
1) send H5 sync pattern (already supported by hci_h5)
2) get LMP version (already supported by btrtl)
3) get ROM version (already supported by btrtl)
4) load the firmware and config for the current chipset (already
supported by btrtl)
5) read UART settings from the config blob (currently not supported)
6) send UART settings via a vendor command to the device (which changes
the baudrate of the device and enables or disables flow control
depending on the config)
7) change the baudrate and flow control settings on the host
8) send the firmware and config blob to the device (already supported by
btrtl)
The main reason why the initialization has to be split is step #7. This
requires changes to the underlying "bus", which should be kept outside
of the "generic" btrtl driver.
The idea for this split is borrowed from the btbcm driver but adjusted
where needed (the btrtl driver for example needs two blobs: firmware and
config, while the btbcm only needs one).
This also prepares the code for step #5 (parsing the config blob) by
centralizing the code which loads the firmware and config blobs and
storing the result in the new struct btrtl_device_info.

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.

In commit f44cb4b19ed4 ("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.

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:

btbcm_setup_patchram() starts with initializing the controller (and
getting the firmware filename) and then after loading the firmware,
does a re-init. This almost entirely duplicates the code in
btbcm_initialize(), use that function instead.

btbcm_finalize() does a re-init of the controller, which is almost the
same as the initial init. Modify btbcm_initialize() so that it can be
used for this re-init and modify btbcm_finalize() to use it.
As an added bonus this also makes the dev_info from btbcm_finalize()
use the proper hw_name instead of always printing "BCM".

Make btbcm_initialize() also work for USB connected device,
btbcm_initialize() and btbcm_setup_patchram() are quite similar,
this is a preparation patch for making btbcm_setup_patchram() use
btbcm_initialize() to remove the code duplication.

btbcm_setup_patchram() was using the upper nibble of the revision code to
determine if we are dealing with an uart or USB connected bcm-bt device,
but just as btbcm_initialize() has started accepting 1 and 2 as uart
connected devices, I've now encountered an USB connected device (0a5c:216c)
which has 0 in the upper nibble. So it seems that the upper nibble is not
really a reliable indicator of the bus type.
Instead check hdev->bus which does give us a reliable indication. This
fixes the patchram code trying to load the patchram by the fallback BCM.hcd
filename, now it correctly requests BCM43142A0-0a5c-216c.hcd.

Since there is no rampatch for dragonboard820c QCA controller

Interrupts specified through an "Interrupt" ACPI resource (versus through
a "GpioInt" resource) are now always assumed to be active low.
When this change was originally made the Thinkpad 8 quirk was kept around
because it was uncertain if the Thinkpad 8 uses an "Interrupt" or a
"GpioInt" resource.
Bug https://bugzilla.kernel.org/show_bug.cgi?id=196701 has a DSDT for the
Thinkpad 8 attached and it uses an "Interrupt" resource, so the quirk is
not necessary and the quirk, as well as the irq-active-low quirk handling
code can be removed.

The Meegopad T08 hdmi-stick (think Intel computestick) has a brcm43430
wifi/bt combo chip. The BCM2E90 ACPI device describing the BT part does
contain a valid ActiveLow GpioInt entry, but the GPIO it points to never
goes low, so either the IRQ pin is not connected, or the ACPI resource-
table points to the wrong GPIO.
Eitherway things will not work if we try to use the specified IRQ, this
commits adds a DMI based broken-irq blacklist and disables use of the IRQ
and thus also runtime-pm for devices on this list.
This blacklist starts with the the Meegopad T08, fixing bluetooth not
working on this hdmi-stick. Since this is not a battery powered device
the loss of runtime-pm is not really an issue.
