Loic Poulain b98469f4be Bluetooth: hci_intel: Introduce LPM support
Enable controller Low-Power-Mode if we have a pdev to manage host
wake-up. Once LPM is enabled, controller notifies its TX status via
a vendor specific packet (tx_idle/tx_active).
tx_active means that there is more data upcoming from controller.
tx_idle means that controller can be put in suspended state.

Loic Poulain 1ab1f239bf Bluetooth: hci_intel: Add support for platform driver
A platform device can be used to provide some specific resources in
order to manage the controller. In this first patch we retrieve the
reset gpio which is used to power on/off the controller.

The main issue is to match the current tty with the correct pdev.
In case of ACPI, we can easily find the right tty/pdev pair because
they are both child of the same UART port.

If controller is powered-on from the driver, we need to wait for a
HCI boot event before being able to send any command.

Loic Poulain ff2895592f Bluetooth: hci_intel: Add Intel baudrate configuration support
Implement the set_baudrate callback for hci_intel.
 - Controller requires a read Intel version command before updating
   its baudrate.
 - The operation consists in an async cmd since the controller does
   not respond at the same speed.
 - Wait 100ms to let the controller change its baudrate.
 - Clear RTS until we change our own UART speed

Manage speed change in the setup function, we need to restore the oper
speed once chip has booted on patched firmware.

Daniel Drake d63b282645 Bluetooth: btusb: match generic class code in interface descriptor
btusb currently has a generic match on USB device descriptors:
        { USB_DEVICE_INFO(0xe0, 0x01, 0x01) },

However, http://www.usb.org/developers/defined_class states:

  Base Class E0h (Wireless Controller)
  This base class is defined for devices that are Wireless controllers.
  Values not shown in the table below are reserved. These class codes are
  to be used in Interface Descriptors, with the exception of the Bluetooth
  class code which can also be used in a Device Descriptor.

Add a match on the interface descriptors accordingly.

This fixes compatibility with the RTL8723AU device shown below.
This device conforms to the USB Interface Association Descriptor
specification, which requires the device to have class ef/02/01.
The extra IAD descriptor then specifies that interfaces 0 and 1
belong to the same function/driver, which is true. Provided that
the Bluetooth device class spec accepts use of the IAD, I imagine that
technically, all btusb devices should be configured like this.

Loic Poulain ca93cee5a5 Bluetooth: hci_uart: Add basic support for Intel Lightning Peak devices
The Intel Lightning Peak devices do not come with Bluetooth firmware
loaded and thus require a full download of the operational Bluetooth
firmware when the device is attached via the Bluetooth line discipline.

Lightning Peak devices start with a bootloader mode that only accepts
a very limited set of HCI commands. The supported commands are enough
to identify the hardware and select the right firmware to load.

Chris Mason 7bee8b08c4 Bluetooth: btbcm: allow btbcm_read_verbose_config to fail on Apple
Commit 1c8ba6d013 moved around the setup code for broadcomm chips,
and also added btbcm_read_verbose_config() to read extra information
about the hardware.  It's returning errors on some macbooks:

Bluetooth: hci0: BCM: Read verbose config info failed (-16)

Which makes us error out of the setup function.  Since this
probe isn't critical to operate the chip, this patch just changes
things to carry on when it fails.

This patch adds the routine to apply the DDC parameter from device
specific ddc file.

Once the device is rest to operational mode, optionally, it can
download the device specific configration (DDC) parameters before
the BlueZ starts the stack initialization.

It opens the DDC file based on HW_VARIANT and DEV_REVISION and
send ID/Value with HCI_Intel_Write_DDC command.

Format of DDC file
DDC file contains one or more number of DDC structure.

DDC Structure
It has 'Length' field of one octet, DDC 'ID' field of
two octets followed by the array of DDC 'Value' that gives
the value of parameters itself.
'Length' contains the length of DDC 'ID' and DDC 'Value'.

Marcel Holtmann e66890a96a Bluetooth: btusb: Fix secure send command length alignment on Intel 8260
This patch fixes the command length alignment issue for Intel Bluetooth
8260.

The length of parameters in the firmware downloading command must be
multiplication of 4. If not, the command must append Intel_NOP command
with extra parameters, zeros, at the end, and the firmware file is
already included Intel_NOP command for alignment.

This patch checks the next command and if the next command is Intel_NOP
command, it reads the Intel_NOP command and send them together.

For example, if the data from the firmware file looks like this:
8E FC 03 11 22 33 02 FC 03 00 00 00

Previously, btusb sends two commands:
09 FC 06 8E FC 03 11 22 33
09 FC 06 02 FC 03 00 00 00

This won't work because the length of parameters are 6 which violates
the 4 byte alignment.

This patch will append them together and send as one command:
09 FC 0C 8E FC 03 11 22 33 02 FC 03 00 00 00

Frederic Danis 75e167e6f0 Bluetooth: btbcm: Add helper functions for UART setup
Firmware loading may reset the controller UART speed and needs to set
host UART speed back to init speed.

UART drivers setup is split in 3 parts:
- btbcm_initialize() resets the controller and returns the firmware
  name based on controller revision and sub_version.
- btbtcm_patchram() (already existing and public), which takes the
  firmware name as parameter, requests the firmware and loads it to
  the controller.
- btbcm_finalize() which resets the controller, reads local version
  and checks if the controller address is a default one or not.

Remove firmware name retrieval for UART controllers from
btbcm_setup_patchram().

the updated firmware is quietly lost - the USB hub doesn't notice any
status change upon resume, but some kind of reset has definitely
happened as the LMP subversion has reverted to its original value.

Set the reset_resume flag to trigger probe and upload the new firmware
again.

Like the vendor code, I assume this is not needed when the device is
selected as a wakeup source and hence will retain power during suspend.
On the 2 products I have to hand, when trying this configuration the
hardware seems unable to keep the device powered up during suspend.
The USB hub then detects a status change on resume and does a reset,
so we do not end up in broken state.

Frederic Danis 43b79209b5 Bluetooth: btbcm: Fix calls to __hci_cmd_sync()
Remove test of command reply status as it is already performed by
__hci_cmd_sync().

__hci_cmd_sync_ev() function already returns an error if it got a
non-zero status either through a Command Complete or a Command
Status event.

For both of these events the status is collected up in the event
handlers called by hci_event_packet() and then passed as the second
parameter to req_complete_skb(). The req_complete_skb() callback in
turn is hci_req_sync_complete() for __hci_cmd_sync_ev() which stores
the status in hdev->req_result. The hdev->req_result is then further
converted through bt_to_errno() back in __hci_cmd_sync_ev().

Daniel Drake a2698a9bf9 Bluetooth: btusb: Add Realtek 8723A/8723B/8761A/8821A support
Realtek ship a variety of bluetooth USB devices that identify
themselves with standard USB Bluetooth device class values, but
require a special driver to actually work. Without that driver,
you never get any scan results.

More recently however, Realtek appear to have wisened up and simply
posted a firmware update that makes these devices comply with
normal btusb protocols. The firmware needs to be uploaded on each boot.

Based on Realtek code from https://github.com/lwfinger/rtl8723au_bt
('new' branch).

This enables bluetooth support in the Gigabyte Brix GB-BXBT-2807 which
has this RTL8723BE USB device:

There is no change to the USB descriptor after firmware update,
however the version read by HCI_OP_READ_LOCAL_VERSION changes from
0x8723 to 0x3083.

This has also been tested on RTL8723AE and RTL8821AE. Support for
RTL8761A has also been added, but that is untested.

and UART transports. This creates a separate module that eventually
will hold all Intel specific commands, but for now just start with the
commands to change the Bluetooth public address and check for the
default address.

Marcel Holtmann 79b8df9362 Bluetooth: hci_uart: Provide generic H:4 receive framework
Future H:4 based UART drivers require custom packet types and custom
receive functions. To support this, extended the h4_recv_buf function
with a packet definition table.

For the default H:4 packets types of ACL data, SCO data and events,
provide helpers to reduce the amount of code duplication.

The commit d0ac9eb72 (Bluetooth: btusb: Ignore unknown Intel devices
with generic descriptor) disabled these older controllers. To enable
them again, put them into the blacklist and mark them clearly as CSR
based controllers.

Marcel Holtmann 18835dfa3a Bluetooth: btusb: Use matching names for Broadcom firmware files
The Broadcom firmware files are named with firmware version information
encoded into lmp_subver field. So BCM20702B0_002.001.014.0527.0607.hex
would be represented by 0x410e. To allow for an easier decoding of the
actual firmware names, provide an internal table that does the mapping
and request the firmware file by name.

Bluetooth: hci0: BCM20702B0 (002.001.014) build 0607

Now the complicated encoding of lmp_subver will be decoded and turned
into the name and firmware version information from the firmware files.

The previous attempt of using udev->product failed badly since it never
contains any matching entry to the actual hardware or firmware files
distributed by Broadcom in their Windows drivers. It is even worse since
it can change depending on if the internal bootstrapping happened before
the USB bus enumeration or after. This caused many race conditions.

Tedd Ho-Jeong An bfbd45e9ac Bluetooth: Add device shutdown routine for Intel Bluetooth device
This patch adds the device shutdown routine for Intel Bluetooth device.

Some platforms have BT LED issue with Intel Bluetooth device that BT LED goes
off 5 seconds after BT is turned off

For Intel Bluetooth device, the BT LED is turned off when:
- there is no active connection or radio activity
- USB is suspend

So, when the BT is turned off, it takes 5 seconds because USB suspend timeone
is 5 seconds by default. And if the USB suspend is not enabled, BT LED won't be
turned off.

To fix this issue, recently Intel Bluetooth firmware patch had been submitted
to turn off the BT LED immediately by the vendor specific command(0xFC3F). And
this patch sends this command to the device before closing the device.

For backward compatibility of this command  with old firmware, this command was
supported before, but it behaves same as HCI_RESET internally. So, it won't be
the problem even if the system doesn't have the latest firmware patch.

tty_set_termios() is an internal helper intended for file scope use.

UART drivers which are capable of driving the RTS pin must
properly handle the tiocmset() method, regardless of termios settings.
A failure to do so is a UART driver bug and should be fixed there.
Do not use this interface to workaround UART driver bugs.

Johan Hedberg a087a98e07 Bluetooth: btusb: Fix race when waiting for BTUSB_DOWNLOADING
The test for BTUSB_DOWNLOADING must be after adding to the wait queue
and setting the TASK_INTERRUPTIBLE state. Otherwise the flag may get
cleared after we test for it and we end up getting a timeout since
schedule_timeout() waits for the full duration. This patch uses a
wait_on_bit_timeout() + wake_up_bit(). To perform the task both
race-free as well as in a much simpler way.

Since there's no global wait_on_bit_timeout() helper yet (even though
all the building blocks for it are in place) this patch creates a
temporary local btusb copy of it until the global one has made it to
upstream trees.

Marcel Holtmann ce6bb9297c Bluetooth: btusb: Handle out of order firmware loading complete event
When loading the Intel firmware it can happen that the firmware loading
complete vendor event arrives before the command complete event for the
last firmware fragment.

< HCI Command: Vendor (0x3f|0x0009) plen 7
        01 02 fc 03 00 00 00
> HCI Event: Vendor (0xff) plen 5
        06 00 00 00 00
> HCI Event: Command Complete (0x0e) plen 4
      Vendor (0x3f|0x0009) ncmd 31
        Status: Success (0x00)

This is mainly caused by the fact that the vendor command and its
command complete event are transported over the bulk endpoints. The
firmware loading complete event however is send over the interrupt
endpoint. So with just bad timing one event arrives before the other.

Currently the code does not account for it. There are precautions for
receiving firmware loading complete event quickly, but not for receiving
it before the command complete.

Introduce an extra flag that tracks when the firmware sending has
completed from the driver point of view and track the completion of
the firmware loading procedure with a different flag. That way the
wakeup can be handled properly.

Previous patches to the btusb driver allow overwriting the handling
for bulk receive endpoint packets and HCI events processing. The
firmware loading makes heavy use of these new internal callbacks.

This patch also introduces additional internal states to track if the
device is in bootloader or operational mode. This allows for correct
feedback about the firmware loading procedure.

Since this is an unsual USB vendor ID (0x19ff), these dongles are added
via USB_DEVICE macro and not USB_VENDOR_AND_INTERFACE_INFO as done for
mainstream Broadcom based dongles.

The latest known working firmware is BCM20702B0_002.001.014.0527.0557.hex
which needs to be converted using hex2hcd utility and then installed
as /lib/firmware/brcm/BCM20702A0-19ff-0239.hcd to make this device fully
operational.

Bluetooth: hci0: BCM: patching hci_ver=06 hci_rev=2000 lmp_ver=06 lmp_subver=410e
Bluetooth: hci0: BCM: firmware hci_ver=06 hci_rev=222d lmp_ver=06 lmp_subver=410e

With this firmware the device reports support for connectionless slave
broadcast (master and slave) feature used by 3D Glasses and TVs.

  < HCI Command: Read Local Extended Features (0x04|0x0004) plen 1
          Page: 2
  > HCI Event: Command Complete (0x0e) plen 14
        Read Local Extended Features (0x04|0x0004) ncmd 1
          Status: Success (0x00)
          Page: 2/2
          Features: 0x0f 0x00 0x00 0x00 0x00 0x00 0x00 0x00

            Connectionless Slave Broadcast - Slave
            Synchronization Train
            Synchronization Scan

However there are some flaws with this feature. The Set Event Mask Page 2
command is actually not supported and with that all connectionless slave
broadcast events are always enabled.

  < HCI Command: Set Event Mask Page 2 (0x03|0x0063) plen 8
          Mask: 0x00000000000f0000
            Synchronization Train Received
            Connectionless Slave Broadcast Receive
            Connectionless Slave Broadcast Timeout
            Truncated Page Complete
  > HCI Event: Command Complete (0x0e) plen 4
        Set Event Mask Page 2 (0x03|0x0063) ncmd 1
          Status: Unknown HCI Command (0x01)

In addition the Synchronization Train Received event is actually broken
on this controller. It mixes up the order of parameters. According to the
Bluetooth Core specification the fields are like this:

  struct hci_ev_sync_train_received {
          __u8     status;
          bdaddr_t bdaddr;
          __le32   offset;
          __u8     map[10];
          __u8     lt_addr;
          __le32   instant;
          __le16   interval;
          __u8     service_data;
  } __packed;

This controller however sends the service_data as 5th parameter instead
of having it as last parameter.

  struct hci_ev_sync_train_received {
          __u8     status;
          bdaddr_t bdaddr;
          __le32   offset;
          __u8     map[10];
          __u8     service_data;
          __u8     lt_addr;
          __le32   instant;
          __le16   interval;
  } __packed;

So anybody trying to use this hardware for utilizing connectionless slave
broadcast receivers (aka 3D Glasses), be warned about this shortcoming.

Firmware is extracted from the latest Broadcom BCM4352 Windows driver
by extracting the zip and searching the .hex file names for '17cf'.

The hex file must then be converted to hcd format using the hex2hcd
utility and then moved to /lib/firmware/brcm/.

Marcel Holtmann 4fcef8ed75 Bluetooth: Fix issue with Roper Class 1 Bluetooth Dongle
The Roper Class 1 Bluetooth Dongle is another device that claims to
support Bluetooth 1.2 specification, but does not support the HCI
command for reading the local supported commands.

  < 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

      LMP Version: 1.2 (0x2) LMP Subversion: 0x757
      Manufacturer: Silicon Wave (11)

It clearly claims Bluetooth 1.2 support and in that regard has the
same issue as the AVM BlueFritz! USB devices (Silicon Wave based),
but the HCI Read Local Supported Commands command fails.

  < HCI Command: Read Local Supported Commands (0x04|0x0002) plen 0

Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"

The firmware was extracted from a Windows 7 32-bit installation
and converted from 'hex' to 'hcd' for use in Linux.

The firmware is named "BCM20702A0_001.001.024.0156.0204.hex"
and is located in "%SYSTEMROOT%\system32\drivers\"
(md5 d126e6c4e0e669d76c38cf9377f76b7f)
(sha1 145d1850b2785a953233b409e7ff77786927c7d2)

The firmware file is also available as a download at
http://support.ts.fujitsu.com/Download/
contained in "FTS_WIDCOMMBluetoothSoftware_6309000_1072149.zip"

Search for the file Win32/bcbtums-win7x86-brcm.inf in the archive,
look for the vendor and product ID of your adapter, see the section
'devices' in that file to find out what device name it uses. See
the device entry in the inf file (in my case it was 'RAMUSBE031')
to find out which hex file you need to convert to hcd for upload

'hcd' file should be placed at "brcm/BCM20702A0-0489-e031.hcd"
inside the firmware directory (e.g. "/lib/firmware")

Xinming Hu dc759613b0 Bluetooth: btmrvl add firmware dump support
This patch adds firmware dump support for marvell
bluetooth chipset. Currently only SD8897 is supported.
This is implemented based on dev_coredump, a new mechnism
introduced in kernel 3.18rc3

Firmware dump can be trigger by
echo 1 > /sys/kernel/debug/bluetooth/hci*/config/fw_dump
and when the dump operation is completed, data can be read by
cat /sys/class/devcoredump/devcd*/data

We have prepared following script to divide fw memory
dump data into multiple files based on memory type.

 [root]# cat btmrvl_split_dump_data.sh
 #!/bin/bash
 # usage: ./btmrvl_split_dump_data.sh dump_data

 fw_dump_data=$1

 mem_type="ITCM DTCM SQRAM APU CIU ICU MAC EXT7 EXT8 EXT9 EXT10 EXT11 EXT12 EXT13 EXTLAST"

 for name in ${mem_type[@]}
 do
         sed -n "/Start dump $name/,/End dump/p" $fw_dump_data  > tmp.$name.log
         if [ ! -s tmp.$name.log ]
                 then
                         rm -rf tmp.$name.log
                 else
                         # Remove the describle info "Start dump" and "End dump"
                         sed '1d' tmp.$name.log | sed '$d' > /data/$name.log
                         if [ -s /data/$name.log ]
                         then
                                 echo "generate /data/$name.log"
                         else
                                 sed '1d' tmp.$name.log | sed '$d' > /var/$name.log
                                 echo "generate /var/$name.log"
                         fi
                         rm -rf tmp.$name.log

Marcel Holtmann b34490011d Bluetooth: Use HCI_EV_HARDWARE_ERROR define for event payload
When constructing the event payload for the HCI_Hardware_Error event
message, use the HCI_EV_HARDWARE_ERROR define.

In addition rename the variables from hard_err to hw_err to clearly
indicate that this is about the hardware error and not a hard error.

Loic Poulain b509c02d0f Bluetooth: HCI H5 peer reset detection
H5 Specification says:
If a SYNC message is received while in the Active State, it is
assumed that the peer device has reset. The local device should
therefore perform a full reset of the upper stack, and start Link
Establishment again at the Uninitialized State. Upon entering the
Active State, the first packet sent shall have its SEQ and ACK
numbers set to zero.

This patch resets the HCI H5 driver data/state to unitialized and
reports an HCI hardware error event to notify the upper stack that
HCI synchronization has been lost. H5 will be re-synchronized and
upper stack should generate an HCI Reset command.

Marcel Holtmann 803b58367f Bluetooth: btusb: Implement driver internal packet reassembly
When receiving USB interrupt, bulk or isochronous packet, they normally
come in fragments. So far the driver just handed each fragment off to
the hci_recv_fragment function of the Bluetooth core. That function is
however so specific that is does not belong in the core. This patch
implements the same reassembly logic in the driver.

In addition this fixes a long standing bug where multiple complete
packets are received within a single USB packet.

Marcel Holtmann 047b2ec8d3 Bluetooth: btusb: Separate TX URB allocation and submission
The complete TX URB handling is done via a switch statement in the
btusb_send_frame function. To allow for more clear separation between
control, bulk and isoc URBs, split them into allocation and submission.

Previously the inc_tx function has been used for tracking in-flight
URB for HCI commands and ACL data packets. Convert that into a common
function that either submits the URB or queues it when needed.

This provides the flexibility to allow vendor specific hdev->send_frame
callbacks without having to duplicate the whole URB handling logic.

Himangi Saraogi 3bbaf81206 Bluetooth: Remove typedef bt3c_info_t
The Linux kernel coding style guidelines suggest not using typedefs
for structure types. This patch gets rid of the typedef for
bt3c_info_t. Also, the name of the struct is changed to drop the _t,
to make the name look less typedef-like.

The following Coccinelle semantic patch detects the case:

@tn@
identifier i;
type td;

-typedef
 struct i { ... }
-td
 ;

@@
type tn.td;
identifier tn.i;
