At the moment we only support ACPI enumeration for serial port attached
RTL bluetooth controllers.
This commit adds a dependency on ACPI to the BT_HCIUART_RTL configuration
option, fixing the following warning when ACPI is not enabled:

The linkage between the bluetooth driver and the wireless
driver is not defined properly, leading to build problems
such as:
warning: (BT_HCIRSI) selects RSI_COEX which has unmet direct dependencies (NETDEVICES && WLAN && WLAN_VENDOR_RSI && BT_HCIRSI && RSI_91X)
drivers/net/wireless/rsi/rsi_91x_main.o: In function `rsi_read_pkt':
(.text+0x205): undefined reference to `rsi_bt_ops'
As the dependency is actually the reverse (RSI_91X uses
the BT_RSI driver, not the other way round), this changes
the dependency to match, and enables the bluetooth driver
from the RSI_COEX symbol.

Commit 27378f4c1b92 ("Bluetooth: Avoid WARN splat due to missing
GPIOLIB") amended Kconfig to select GPIOLIB if BT_HCIUART_NOKIA,
BT_HCIUART_INTEL or BT_HCIUART_BCM is enabled since all three drivers
require it to function.
The diagnosis was correct but the treatment was not. As stated in
Documentation/gpio/consumer.txt:
Guidelines for GPIOs consumers
==============================
Drivers that can't work without standard GPIO calls should have
Kconfig entries that depend on GPIOLIB.

On many laptops the btusb device is the only USB device not having USB
autosuspend enabled, this causes not only the HCI but also the USB
controller to stay awake, together using aprox. 0.4W of power.
Modern ultrabooks idle around 6W (at 50% screen brightness), 3.5W for
Apollo Lake devices. 0.4W is a significant chunk of this (7 / 11%).
The btusb driver already contains code to allow enabling USB autosuspend,
but currently leaves it up to the user / userspace to enable it. This
means that for most people it will not be enabled, leading to an
unnecessarily high power consumption.
Since enabling it is not entirely without risk of regressions, this
commit adds a Kconfig option so that Linux distributions can choose to
enable it by default. This commit also adds a module option so that when
distros receive bugs they can easily ask the user to disable it again
for easy debugging.

Signed-off-by: David S. Miller <davem@davemloft.net>

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

The hci_bcm platform-device hack which was used to implement
power management for ACPI devices is being replaced by a
serial-device-bus implementation.
Unfortunately, when the corresponding change to the ACPI code lands (a
change that will stop enumerating and registering the serial-device-node
child as a platform device) PM will break silently unless serdev
TTY-port controller support has been enabled. Specifically, hciattach
(btattach) would still succeed, but power management would no longer
work.
Although this is strictly a runtime dependency, let's make the driver
depend on SERIAL_DEV_CTRL_TTYPORT, which is the particular serdev
controller implementation used by the ACPI devices currently managed by
this driver, to avoid breaking PM without anyone noticing.
Note that the driver already has a (build-time) dependency on the serdev
bus code.

With CONFIG_SERIAL_DEV_BUS=m, the hci_serdev.o file does not actually

to a link error with anything referring to it:
ERROR: "hci_uart_register_device" [drivers/bluetooth/hci_nokia.ko] undefined!
scripts/Makefile.modpost:91: recipe for target '__modpost' failed
Changing this in the Makefile would cause another problem when
hci_uart itself is built-in and cannot reference symbols from the
serdev module.
This tries to address both problems by introducing a new hidden
Kconfig symbol that controls both the compilation of hci_serdev.o
and whether the Nokia driver can be selected. This seems to address
the problem for me, though there might be a better way to do it.

This driver implements support for iBT2.1 Bluetooth controller embedded
in the AG620 communication combo. The controller needs to be configured
with bddata and can be patched with a binary patch file (pbn).
These operations are performed in manufacturing mode.

The change to bpa10x to use the h4_recv_buf helper added a dependency
on BT_HCIUART. This was incorrectly added to Kconfig by adding a
'select' statement, which now in turn causes build failures
when CONFIG_TTY is not set:
warning: (BT_HCIBPA10X) selects BT_HCIUART which has unmet direct dependencies (NET && BT && TTY)
vers/built-in.o: In function `hci_uart_tty_receive':
fpga-mgr.c:(.text+0x282824): undefined reference to `tty_unthrottle'
drivers/built-in.o: In function `hci_uart_tty_ioctl':
fpga-mgr.c:(.text+0x282aa0): undefined reference to `n_tty_ioctl_helper'
drivers/built-in.o: In function `hci_uart_flush':
This replaces the 'select BT_HCIUART' dependency with 'depends on', which
does not have this kind of problem. Alternatively, one could add 'depends
on TTY', but avoiding 'select' on user-visible options is generally the
preferred choice as that does not introduce the potential for dependency
loops or incomplete dependency chains.

Selecting just BT_HCIUART_H4 is not enough and it also needs to select
BT_HCIUART to avoid this warning:
warning: (BT_HCIBPA10X) selects BT_HCIUART_H4 which has unmet direct
dependencies (NET && BT && BT_HCIUART)

The manually coded frame reassembly is actually broken. The h4_recv_buf
helper from the UART driver is a perfect fit for frame reassembly for
this driver. So just export that function and use it here as well.

Add regmap ibt to support Intel Bluetooth silicon register access
over HCI. Intel BT/FM combo chip allows to read/write some registers
(e.g. FM registers) via its HCI interface.
Read/Write operations are performed via a HCI transaction composed of
a HCI command (host->controller) followed by a HCI command complete
event (controller->host). Read/Write Command opcodes can be specified
to the regmap init function.
We define data formats which are intel/vendor specific.
Register Read/Write HCI command payload (Host):
Field: | REG ADDR | MODE | DATA_LEN | DATA... |
size: | 32b | 8b | 8b | 8b* |
Register Read HCI command complete event payload (Controller):
Field: | CMD STATUS | REG ADDR | DATA... |
size: | 8b | 32b | 8b* |
Register Write HCI command complete event payload (Controller):
Field: | CMD_STATUS |
size: | 8b |
Since this payload is HCI encapsulated, Little Endian byte order is
used.
Write/Read Example:
If we write 0x0000002a at address 0x00008c04, with opcode_write 0xfc5d,
The resulting transaction is (btmon trace):
< HCI Command (0x3f|0x005d) plen 10 [hci0]
04 8c 00 00 02 04 2a 00 00 00
> HCI Event (0x0e) plen 4
Unknown (0x3f|0x005d) ncmd 1
00
Then, if we read the same register with opcode_read 0xfc5e:
< HCI Command (0x3f|0x005e) plen 6 [hci0]
04 8c 00 00 02 04
> HCI Event (0x0e) plen 12 [hci0]
Unknown (0x3f|0x005e) ncmd 1
00 04 8c 00 00 2a 00 00 00

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.

The majority of Intel Bluetooth vendor commands are shared between USB

will hold all Intel specific commands, but for now just start with the
