Bluetooth: btmrvl: use cal-data from device-tree instead of conf file

2013-12-04T13:09:03+00:00

Some ARM versions of Chromebook need to download a new calibration
data from host driver to firmware. They do have EEPROM but still
need a piece of new calibration data in test mode.

The cal-data is platform dependent. It's simpler and more feasible
to use device tree based cal-data instead of configuration file
based cal-data.

This patch remove configuration file based cal-data downloading
and replace it using cal-data from device tree.

When CONFIG_OF is not selected, or the specific property is not
present in the device tree, the calibration downloading will not
happen.

Bluetooth: Provide hdev parameter to hci_recv_frame() driver callback

2013-10-11T07:45:34+00:00

To avoid casting skb->dev into hdev, just let the drivers provide
the hdev directly when calling hci_recv_frame() function.

This patch also fixes up all drivers to provide the hdev.

There are two places where DIV_ROUND_UP may be used. It makes code a bit
clearer.

Bluetooth: btmrvl: report error if verify_fw_download times out

2013-04-23T23:55:55+00:00

FW does the synchronization of the different modules during init.
It will report different modules, that it is ready at different times.
The fw download 'winner' will be reported fw ready first. Without this
patch, btmrvl was already continuing before the FW told it too. Probably
on behalf of the 'winner' which then never sees FW ready and times out.
