Bluetooth: btintel: Add manufacturing enter/exit helpers

2015-12-09T23:51:50+00:00

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.

Bluetooth: btintel: Enable extra Intel vendor events

2015-10-21T04:34:11+00:00

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.

Bluetooth: btintel: Add diagnostic support for older controllers

2015-10-20T22:49:22+00:00

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.

For Intel controllers with firmware that allows tracing of baseband
functionality this allows enabling it via set_diag driver callback.

Bluetooth: btintel: Add iBT register access over HCI support

2015-10-03T17:03:15+00:00

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
