Solomon Peachy cf1ad8f947 wireless: cw1200: Use consistent internal locking conventions
The cw1200_irq_handler() function expects the hwbus lock to be held when
it is called.  On the SDIO platform, this lock is implemented in terms

This trivial patch makes it explicit that we are performing the hwbus

Tedd Ho-Jeong An d2bee8fb6e Bluetooth: Enable autosuspend for Intel Bluetooth device
This patch enables autosuspend for Intel Bluetooth device.

After btusb is loaded for Intel Bluetooth device, the power/control
attribute contains "on" value by default which disables the autosuspend.
Based on the USB PM document(Documentation/usb/power-management.txt),
kernel disabled the autosuspend for all devices other than hub by default.

"The USB specification states that all USB devices must support power
management.  Nevertheless, the sad fact is that many devices do not
support it very well.  You can suspend them all right, but when you
try to resume them they disconnect themselves from the USB bus or
they stop working entirely.  This seems to be especially prevalent
among printers and scanners, but plenty of other types of device have
the same deficiency.

For this reason, by default the kernel disables autosuspend (the
power/control attribute is initialized to "on") for all devices other
than hubs.  Hubs, at least, appear to be reasonably well-behaved in
this regard."

This document also described how the driver can enables the autosuspend
by using an USB api.

"Drivers can enable autosuspend for their devices by calling

	usb_enable_autosuspend(struct usb_device *udev);

in their probe() routine, if they know that the device is capable of
suspending and resuming correctly.  This is exactly equivalent to
writing "auto" to the device's power/control attribute."

For Intel Bluetooth device, the autosuspend needs to be enabled so the
device can transit to LPM(Low Power Mode) and ULPM(Ultra LPM) states after
receiving suspend message from the host.

Andre Guedes 3846220b0d Bluetooth: Refactor hci_disconn_complete_evt
hci_disconn_complete_evt() logic is more complicated than what it
should be, making it hard to follow and add new features.

So this patch does some code refactoring by handling the error cases
in the beginning of the function and by moving the main flow into the
first level of function scope. No change is done in the event handling
logic itself.

Besides organizing this messy code, this patch makes easier to add
code for handling LE auto connection (which will be added in a further
patch).

Andre Guedes abf54a506d Bluetooth: Remove unneeded check in hci_disconn_complete_evt()
According to b644ba336 (patch that introduced HCI_CONN_MGMT_CONNECTED
flag), the HCI_CONN_MGMT_CONNECTED flag tracks when mgmt has been
notified about the connection.

That being said, there is no point in calling mgmt_disconnect_failed()
conditionally based on this flag. mgmt_disconnect_failed() removes
pending MGMT_OP_DISCONNECT commands, it doesn't matter if that
connection was notified or not.

Moreover, if the Disconnection Complete event has status then we have
nothing else to do but call mgmt_disconnect_failed() and return.

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

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.

Marcel Holtmann 33337dcb89 Bluetooth: Fix limited discoverable mode for Zeevo modules
There is an old Panasonic module with a Zeevo chip in there that is
not really operating according to Bluetooth core specification when
it comes to setting the IAC LAP for limited discoverable mode.

For reference, this is the vendor information about this module:

  < HCI Command: Read Local Version Information (0x04|0x0001) plen 0
  > HCI Event: Command Complete (0x0e) plen 12
        Read Local Version Information (0x04|0x0001) ncmd 1
          Status: Success (0x00)
          HCI version: Bluetooth 1.2 (0x02) - Revision 196 (0x00c4)
          LMP version: Bluetooth 1.2 (0x02) - Subversion 61 (0x003d)
          Manufacturer: Zeevo, Inc. (18)

The module reports only the support for one IAC at a time. And that
is totally acceptable according to the Bluetooth core specification
since the minimum supported IAC is only one.

  < HCI Command: Read Number of Supported IAC (0x03|0x0038) plen 0
  > HCI Event: Command Complete (0x0e) plen 5
        Read Number of Supported IAC (0x03|0x0038) ncmd 1
          Status: Success (0x00)
          Number of IAC: 1

The problem arises when trying to program two IAC into the module
on a controller that only supports one.

  < HCI Command: Write Current IAC LAP (0x03|0x003a) plen 7
          Number of IAC: 2
          Access code: 0x9e8b00 (Limited Inquiry)
          Access code: 0x9e8b33 (General Inquiry)
  > HCI Event: Command Status (0x0f) plen 4
        Write Current IAC LAP (0x03|0x003a) ncmd 1
          Status: Unknown HCI Command (0x01)

While this looks strange, but according to the Bluetooth core
specification it is a legal operation. The controller has to
ignore the other values and only program as many as it supports.

  This command shall clear any existing IACs and stores Num_Current_IAC
  and the IAC_LAPs in to the controller. If Num_Current_IAC is greater
  than Num_Support_IAC then only the first Num_Support_IAC shall be
  stored in the controller, and a Command Complete event with error
  code Success (0x00) shall be generated.

This specific controller has a bug here and just returns an error. So
in case the number of supported IAC is less than two and the limited
discoverable mode is requested, now only the LIAC is written to
the controller.

  < HCI Command: Write Current IAC LAP (0x03|0x003a) plen 4
          Number of IAC: 1
          Access code: 0x9e8b00 (Limited Inquiry)
  > HCI Event: Command Complete (0x0e) plen 4
        Write Current IAC LAP (0x03|0x003a) ncmd 1
          Status: Success (0x00)

All other controllers that only support one IAC seem to handle this
perfectly fine, but this fix will only write the LIAC for these
controllers as well.

Arend van Spriel 01376a07bc brcmfmac: move firmware event related defines to fweh.h
The dhd.h file contained a number of definitions that are
related to events received from the firmware. Those are
processed and dispatched in the driver by fweh. Hence the
definitions are moved to its include file.

BCDC is the default protocol layer and being called directly. This
patch installs the functions for this layer dynamically. This allows
new protocols to be added and selected dynamically depending on the
hw capabilties. As currently only BCDC is supported this is always
the installed protocol.
