6c483de1b3 Bluetooth: btintel: Create common Intel Version Read function
The Intel Version Read command is used to retrieve information
about hardware and firmware version/revision of Intel Bluetooth
controllers. This is an Intel generic command used in USB and
UART drivers.

28dc4b92e2 Bluetooth: btintel: Add manufacturing enter/exit helpers
Older Intel controllers need to enter manufacturing mode to perform
some vendor specific operations (patching, configuration...).
Add enter/exit manufaturing methods and refactor existing
manufacturing code.
Exit can be configured to perform a reset. Reset can be performed
either with patches activated or deactivated.

213445b2b4 Bluetooth: btintel: Enable extra Intel vendor events
The Intel Bluetooth controllers can emit extra vendor specific events in
error conditions or for debugging purposes. To make the life easier for
engineers, enable them by default. When the vendor_diag options has been
enabled, then additional debug events are also enabled.

3e24767b78 Bluetooth: btintel: Add diagnostic support for older controllers
For the older controllers like Wilkens Peak and Stone Peak, enabling the
traces requires to switch into manufacturer mode first. This patch does
exactly that, but only for these older controllers.

d06f107bcd Bluetooth: btintel: Add iBT register access over HCI support
Add regmap ibt to support Intel Bluetooth silicon register access
over HCI. Intel BT/FM combo chip allows to read/write some registers
(e.g. FM registers) via its HCI interface.

Read/Write operations are performed via a HCI transaction composed of
a HCI command (host->controller) followed by a HCI command complete
event (controller->host). Read/Write Command opcodes can be specified
to the regmap init function.
We define data formats which are intel/vendor specific.

Register Read/Write HCI command payload (Host):
Field: | REG ADDR | MODE | DATA_LEN | DATA... |
size:  |   32b    |  8b  |    8b    |  8b*    |

Register Read HCI command complete event payload (Controller):
Field: | CMD STATUS | REG ADDR | DATA... |
size:  |     8b     |   32b    |  8b*    |

Register Write HCI command complete event payload (Controller):
Field: | CMD_STATUS |
size:  |     8b     |

Since this payload is HCI encapsulated, Little Endian byte order is
used.

Write/Read Example:

If we write 0x0000002a at address 0x00008c04, with opcode_write 0xfc5d,
The resulting transaction is (btmon trace):

< HCI Command (0x3f|0x005d) plen 10 [hci0]
        04 8c 00 00 02 04 2a 00 00 00
> HCI Event (0x0e) plen 4
      Unknown (0x3f|0x005d) ncmd 1
        00

Then, if we read the same register with opcode_read 0xfc5e:

< HCI Command (0x3f|0x005e) plen 6 [hci0]
        04 8c 00 00 02 04
> HCI Event (0x0e) plen 12 [hci0]
      Unknown (0x3f|0x005e) ncmd 1
        00 04 8c 00 00 2a 00 00 00

145f2368c5 Bluetooth: btintel: Add Device Configuration support
btintel_load_ddc_config retrieves the ddc file and sends its content
via DDC commands (opcode 0xfc8b).

The ddc file should contain one or more DDC structures.
A DDC structure is composed of the folowing fields:
field: | DDC LEN |    DDC ID    |   DDC VALUE   |
size:  | 1 byte  |    2 bytes   |  DDC LEN - 2  |

48f0ed1bb6 Bluetooth: btintel: Introduce generic Intel Bluetooth support
The majority of Intel Bluetooth vendor commands are shared between USB
and UART transports. This creates a separate module that eventually
will hold all Intel specific commands, but for now just start with the
commands to change the Bluetooth public address and check for the
default address.
