* Bluetooth: NXP: Add protocol support for NXP Bluetooth chipsetsNeeraj Sanjay Kale2023-04-241-0/+12
| | | | | | | | | | | | | | | | | | | | | This adds a driver based on serdev driver for the NXP BT serial protocol based on running H:4, which can enable the built-in Bluetooth device inside an NXP BT chip. This driver has Power Save feature that will put the chip into sleep state whenever there is no activity for 2000ms, and will be woken up when any activity is to be initiated over UART. This driver enables the power save feature by default by sending the vendor specific commands to the chip during setup. During setup, the driver checks if a FW is already running on the chip by waiting for the bootloader signature, and downloads device specific FW file into the chip over UART if bootloader signature is received..

* Bluetooth: mediatek: add support for MediaTek MT7663S and MT7668S SDIO devicesSean Wang2019-04-231-0/+11
| | | | | | | | | | | | | | | | | | | | | | This adds the support of enabling MT7663S and MT7668S SDIO-based Bluetooth function. There are quite many differences between MT766[3,8]S and standard Bluetooth SDIO devices such as Type-A and Type-B devices. For example, MT766[3,8]S have its own SDIO registers layout, definition, SDIO packet format, and the specific flow should be programmed on them to complete the device initialization and low power control and so on. Currently, there are many independent programming sequences from the transport which are exactly the same as the ones in btusb.c about MediaTek support [1] and btmtkuart.c. We can try to split the transport independent Bluetooth setups on the advance, place them into the common files and allow varous transport drivers to reuse them in the future.

* Bluetooth: btusb: Add a Kconfig option to enable USB autosuspend by defaultHans de Goede2017-12-131-0/+10
| | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* | Bluetooth: avoid silent hci_bcm ACPI PM regressionJohan Hovold2017-10-101-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

| | | | | | | | | | | | | | | | | | | | | | With CONFIG_SERIAL_DEV_BUS=m, the hci_serdev.o file does not actually get built into hci_uart.o as the Makefile doesn't pick it up, leading 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.
