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.

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.

The dhd.h file contained a number of definitions that are
related to events received from the firmware. Those are

the driver module, which is the only one needing to call these.
