Bluetooth: btusb: Trigger Intel FW download error recovery

2019-10-17T07:23:47+00:00

Sometimes during FW data download stage, in case of an error is
encountered the controller device could not be recovered. To recover
from such failures send Intel hard Reset to re-trigger FW download in
following error scenarios:

1. Intel Read version command error
2. Firmware download timeout
3. Failure in Intel Soft Reset for switching to operational FW
4. Boot timeout for switching to operaional FW

Bluetooth: btintel: make array 'param' static, shrinks object size

2018-01-08T20:44:22+00:00

Don't populate the const read-only array 'param' on the stack but instead
make it static. Makes the object code smaller by nearly 20 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  11605	   2629	     64	  14298	   37da	linux/drivers/bluetooth/btintel.o

After:
   text	   data	    bss	    dec	    hex	filename
  11531	   2685	     64	  14280	   37c8	linux/drivers/bluetooth/btintel.o

Bluetooth: Use bt_dev_err and bt_dev_info when possible

2017-10-30T10:25:45+00:00

In case of using BT_ERR and BT_INFO, convert to bt_dev_err and
bt_dev_info when possible. This allows for controller specific
reporting.

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.
