2018-12-05power: reset: gpio-poweroff: add ability to specific active and inactive delaysHeiko Stuebner1-2/+8
Similar to gpio-reset allow to specify active and inactive delays while keeping the 100ms defaults that were used previously all the time. The dt-properties are named the same as in gpio-reset but get an "-ms" suffix as properties should contain such a suffix specifying its unit.

2018-09-16power: reset: at91-poweroff: switch to slow clock before shutdownClaudiu Beznea1-8/+58
The SAMA5D2 NRST input signal is resynchronized with the SLCK clock and it can take up to 2 SLCK cycles (about 90us) for the internal reset to be effective. During this delay, the VDDCORE current consumption may still be high (application-dependent) with the VDDCORE regulator already OFF. Under such conditions, VDDCORE may operate below its operating range leading to potential register corruption. To prevent such situation, it is recommended to decrease significantly the power consumption of the device once the voltage regulator is turned-off. This can be achieved by operating the device at a much lower low frequency. To solve this switch the master clock to slock clock just before writing shutdown command to shutdown controller.

2018-07-06power: vexpress: fix corruption in notifier registrationSudeep Holla1-4/+8
Vexpress platforms provide two different restart handlers: SYS_REBOOT that restart the entire system, while DB_RESET only restarts the daughter board containing the CPU. DB_RESET is overridden by SYS_REBOOT if it exists. notifier_chain_register used in register_restart_handler by design relies on notifiers to be registered once only, however vexpress restart notifier can get registered twice. When this happen it corrupts list of notifiers, as result some notifiers can be not called on proper event, traverse on list can be cycled forever, and second unregister can access already freed memory. So far, since this was the only restart handler in the system, no issue was observed even if the same notifier was registered twice. However commit 6c5c0d48b686 ("watchdog: sp805: add restart handler") added support for SP805 restart handlers and since the system under test contains two vexpress restart and two SP805 watchdog instances, it was observed that during the boot traversing the restart handler list looped forever as there's a cycle in that list resulting in boot hang. This patch fixes the issues by ensuring that the notifier is installed only once.

On the D-Link DIR-685 we get spurious poweroff from infrared. Since that block (CIR) doesn't even have a driver this can be safely ignored, we can revisit this code once we have a device supporting CIR. On the D-Link DNS-313 we get spurious poweroff from the power button. This appears to be an initialization issue: we need to enable the block (start the state machine) before we clear any dangling IRQ. This patch fixes both issues.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2-0/+2
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.

If you do not register a driver and activate the block, the power button on the systems utilizing this SoC will do an uncontrolled power cut, which is why it is important to have a special poweroff driver. The most basic functionality is to just shut down the system by writing a special bit in the control register after the system has reached pm_poweroff. It also handles the poweroff from a button or other sources: When the poweroff button is pressed, or a signal is sent to poweroff from an infrared remote control, or when the RTC fires a special alarm (!) the system emits an interrupt. At this point, Linux must acknowledge the interrupt and proceed to do an orderly shutdown of the system. After adding this driver, pressing the poweroff button gives this dmesg: root@gemini:/ root@gemini:/ gemini-poweroff 4b000000.power-controller: poweroff button pressed calling shutdown scripts.. setting /dev/rtc0 from system time unmounting file systems... umount: tmpfs busy - remounted read-only umount: can't unmount /: Invalid argument The system is going down NOW!

2017-04-14power: reset: syscon-poweroff: add a mask propertyGuy Shapiro1-3/+16
Make the syscon-poweroff driver accept value and mask instead of just value. Prior to this patch, the property name for the value was 'mask'. If only the mask property is defined on a node, maintain compatibility by using it as the value.

Add samx7 support. It is lacking a few bits and needs a new reset function. Signed-off-by: Szemző András <[email protected]> Signed-off-by: Alexandre Belloni <[email protected]> Signed-off-by: Sebastian Reichel <[email protected]>
2017-01-16power: reset: at91-poweroff: timely shutdown LPDDR memoriesAlexandre Belloni3-3/+102
LPDDR memories can only handle up to 400 uncontrolled power off. Ensure the proper power off sequence is used before shutting down the platform. Cc: <[email protected]> # 4.4+ Signed-off-by: Alexandre Belloni <[email protected]> Signed-off-by: Sebastian Reichel <[email protected]>
2016-12-25ktime: Cleanup ktime_set() usageThomas Gleixner1-1/+1
ktime_set(S,N) was required for the timespec storage type and is still useful for situations where a Seconds and Nanoseconds part of a time value needs to be converted. For anything where the Seconds argument is 0, this is pointless and can be replaced with a simple assignment. Signed-off-by: Thomas Gleixner <[email protected]> Cc: Peter Zijlstra <[email protected]>
2016-10-19power: reset: zx-reboot: Fix module autoloadJavier Martinez Canillas1-0/+1
If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/power/reset/zx-reboot.ko | grep alias $ After this patch: $ modinfo drivers/power/reset/zx-reboot.ko | grep alias alias: of:N*T*Czte,sysctrlC* alias: of:N*T*Czte,sysctrl Signed-off-by: Javier Martinez Canillas <[email protected]> Signed-off-by: Sebastian Reichel <[email protected]>
