801b4c027b Bluetooth: btbcm: disable read tx power for some Macs with the T2 Security chip
Some Macs with the T2 security chip had Bluetooth not working.
To fix it we add DMI based quirks to disable querying of LE Tx power.

c03ee9af4e Bluetooth: btbcm: Add 2 missing models to subver tables
Currently the bcm_uart_subver_ and bcm_usb_subver_table-s lack entries
for the BCM4324B5 and BCM20703A1 chipsets. This makes the code use just
"BCM" as prefix for the filename to pass to request-firmware, making it
harder for users to figure out which firmware they need. This especially
is problematic with the UART attached BCM4324B5 where this leads to the
filename being just "BCM.hcd".

Add the 2 missing devices to subver tables. This has been tested on:

1. A Dell XPS15 9550 where this makes btbcm.c try to load
"BCM20703A1-0a5c-6410.hcd" before it tries to load "BCM-0a5c-6410.hcd".

2. A Thinkpad 8 where this makes btbcm.c try to load
"BCM4324B5.hcd" before it tries to load "BCM.hcd"

74530a639a Bluetooth: btbcm: Try multiple Patch filenames when loading the Patch firmware
Currently the bcm_uart_subver_ and bcm_usb_subver_table-s lack entries
for various newer chipsets. This makes the code use just "BCM" as prefix
for the filename to pass to request-firmware, making it harder for users
to figure out which firmware they need. This especially a problem with
UART attached devices where this leads to the filename being "BCM.hcd".

If we add new entries to the subver-tables now, then this will change
what firmware file the kernel looks for, e.g. currently linux-firmware
contains a brcm/BCM-0bb4-0306.hcd file. If we add the info for the
BCM20703A1 to the subver table, then this will change to
brcm/BCM20703A1-0bb4-0306.hcd. This will cause the file to no longer
get loaded breaking Bluetooth for existing users, going against the
no regressions policy.

To avoid this regression make the btbcm code try multiple filenames,
first try the fullname, e.g. BCM20703A1-0bb4-0306.hcd and if that is
not found, then fallback to the name with just BCM as prefix.

This commit also adds an info message which filename was used,
this makes the output look like this for example:

On UART attached devices we do:

1. btbcm_initialize()
2. Setup UART baudrate, etc.
3. btbcm_finalize()

After our previous changes we can now also use btbcm_finalize() from
the btbcm_setup_patchram() function used on USB devices without any
functional changes. This completes unifying the USB and UART paths
as much as possible.

2fcdd562b9 Bluetooth: btbcm: Make btbcm_initialize() print local-name on re-init too
Make btbcm_initialize() get and print the device's local-name on re-init
too, this will make us also print the local-name after loading the
Patch on UART attached devices making things more consistent.

This also removes some code duplication from btbcm_setup_patchram()
and allows more code duplication removal there in a follow-up patch.

0287c5d84f Bluetooth: btbcm: Fold Patch loading + applying into btbcm_initialize()
Instead of having btbcm_initialize() fill a passed in fw_name buffer
and then have its callers use that to request the firmware + load
it into the HCI, make btbcm_initialize() do this itself the first
time it is called (its get called a second time to reset the HCI
after the firmware has been loaded).

This removes some code duplication and makes it easier for further
patches in this series to try more then 1 firmware filename.

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

when having multiple Intel Edison modules in each others range.
The default address also has the LAA (locally administered address)
bit set which prevents a BNEP device from being created, needed for
BT tethering.

22ac191652 Bluetooth: btbcm: Allow using btbcm_initialize() for reinit
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".

this is a preparation patch for making btbcm_setup_patchram() use
btbcm_initialize() to remove the code duplication.

1b2525c05b Bluetooth: btbcm: Stop using upper nibble of rev to chose between uart/USB paths
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.

d456f678a0 Bluetooth: btbcm: Add entry for BCM4343A0 UART bluetooth
This patch adds the device ID for the bluetooth chip used in the
AMPAK AP6212 WiFi+Bluetooth module. The AP6212 is used on several
BananaPi boards, e.g. M2-Ultra.

The AP6212 is a combo module, where the WiFi chip is identified as
BCM43430A0 whereas the Bluetooth chip identifies itself as 4343A0. Note,
the missing '0' before the 'A0'.

The AP6212 needs a firmware blob. Loading the provided firmware file
from the BananaPi vendor, the adapter name is printed as
'BCM4343A0 26MHz AP6212_CL1-0061':

The commit 7bee8b08c4 allows the Read Verbose Config Info to fail
gracefully and not cause the controller setup to abort. It seems the
reason that command failed in the first place was the missing HCI Reset
to bring the controller in full Bluetooth mode.

Apple Bluetooth controllers start out in HID mode and when in that mode
the Read Verbose Config Info command is not allowed. Sending HCI Reset
switches the controller into full HCI mode.

Commit 1c8ba6d013 moved around the setup code for broadcomm chips,
and also added btbcm_read_verbose_config() to read extra information
about the hardware.  It's returning errors on some macbooks:

Bluetooth: hci0: BCM: Read verbose config info failed (-16)

Which makes us error out of the setup function.  Since this
probe isn't critical to operate the chip, this patch just changes
things to carry on when it fails.
