2023-04-19Documentation: LEDs: Describe good names for network LEDsAndrew Lunn1-0/+30
Network LEDs can exist in both the MAC and the PHY. Naming is difficult because the netdev name is neither stable or unique, do to commands like ip link set name eth42 dev eth0, and network namesspaces. Give some example names where the MAC and the PHY have unique names based on device tree nodes, or PCI bus addresses. Since the LED can be used for anything which Linux supports for LEDs, avoid using names like activity or link, rather describe the location on the RJ-45, of what the RJ-45 is expected to be used for, WAN/LAN etc. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> Signed-off-by: David S.

2022-05-24leds: qcom-lpg: Require pattern to follow documentationBjorn Andersson1-3/+5
The leds-trigger-pattern documentation describes how the brightness of the LED should transition linearly from one brightness value to the next, over the given delta_t. But the pattern engine in the Qualcomm LPG hardware only supports holding the brightness for each entry for the period. This subset of patterns can be represented in the leds-trigger-pattern by injecting zero-time transitions after each entry in the pattern, resulting in a pattern that pattern that can be rendered by the LPG. Rework LPG pattern interface to require these zero-time transitions, to make it comply with this subset of patterns and reject the patterns it can't render.

2022-05-04leds: Add driver for Qualcomm LPGBjorn Andersson1-0/+76
The Light Pulse Generator (LPG) is a PWM-block found in a wide range of PMICs from Qualcomm. These PMICs typically comes with 1-8 LPG instances, with their output being routed to various other components, such as current sinks or GPIOs. Each LPG instance can operate on fixed parameters or based on a shared lookup-table, altering the duty cycle over time. This provides the means for hardware assisted transitions of LED brightness. A typical use case for the fixed parameter mode is to drive a PWM backlight control signal, the driver therefor allows each LPG instance to be exposed to the kernel either through the LED framework or the PWM framework. A typical use case for the LED configuration is to drive RGB LEDs in smartphones etc, for which the driver supports multiple channels to be ganged up to a MULTICOLOR LED. In this configuration the pattern generators will be synchronized, to allow for multi-color patterns. The idea of modelling this as a LED driver ontop of a PWM driver was considered, but setting the properties related to patterns does not fit in the PWM API. Similarly the idea of just duplicating the lower bits in a PWM and LED driver separately was considered, but this would not allow the PWM channels and LEDs to be configured on a per-board basis. The driver implements the more complex LED interface, and provides a PWM interface on the side of that, in the same driver.

2021-10-27leds: add new LED_FUNCTION_PLAYER for player LEDs for game controllers.Roderick Colenbrander1-0/+14
Player LEDs are commonly found on game controllers from Nintendo and Sony to indicate a player ID across a number of LEDs. For example, "Player 2" might be indicated as "-x--" on a device with 4 LEDs where "x" means on. This patch introduces LED_FUNCTION_PLAYER1-5 defines to properly indicate player LEDs from the kernel. Until now there was no good standard, which resulted in inconsistent behavior across xpad, hid-sony, hid-wiimote and other drivers. Moving forward new drivers should use LED_FUNCTION_PLAYERx. Note: management of Player IDs is left to user space, though a kernel driver may pick a default value.

2019-07-25leds: core: Add support for composing LED class device namesJacek Anaszewski1-3/+67
Add generic support for composing LED class device name. The newly introduced led_compose_name() function composes device name according to either <color:function> or <devicename:color:function> pattern, depending on the configuration of initialization data. Backward compatibility with in-driver hard-coded LED class device names is assured thanks to the default_label and devicename properties of newly introduced struct led_init_data. In case none of the aforementioned properties was found, then, for OF nodes, the node name is adopted for LED class device name. At the occassion of amending the Documentation/leds/leds-class.txt unify spelling: colour -> color. Alongside these changes added is a new tool - tools/leds/get_led_device_info.sh. The tool allows retrieving details of a LED class device's parent device, which proves that using vendor or product name for devicename part of LED name doesn't convey any added value since that information had been already available in sysfs. The script performs also basic validation of a LED class device name.

2018-09-09Drop all 00-INDEX files from Documentation/Henrik Austad1-32/+0
This is a respin with a wider audience (all that get_maintainer returned) and I know this spams a *lot* of people. Not sure what would be the correct way, so my apologies for ruining your inbox. The 00-INDEX files are supposed to give a summary of all files present in a directory, but these files are horribly out of date and their usefulness is brought into question. Often a simple "ls" would reveal the same information as the filenames are generally quite descriptive as a short introduction to what the file covers (it should not surprise anyone what Documentation/sched/sched-design-CFS.txt covers) A few years back it was mentioned that these files were no longer really needed, and they have since then grown further out of date, so perhaps it is time to just throw them out. A short status yields the following _outdated_ 00-INDEX files, first counter is files listed in 00-INDEX but missing in the directory, last is files present but not listed in 00-INDEX. List of outdated 00-INDEX: Documentation: (4/10) Documentation/sysctl: (0/1) Documentation/timers: (1/0) Documentation/blockdev: (3/1) Documentation/w1/slaves: (0/1) Documentation/locking: (0/1) Documentation/devicetree: (0/5) Documentation/power: (1/1) Documentation/powerpc: (0/5) Documentation/arm: (1/0) Documentation/x86: (0/9) Documentation/x86/x86_64: (1/1) Documentation/scsi: (4/4) Documentation/filesystems: (2/9) Documentation/filesystems/nfs: (0/2) Documentation/cgroup-v1: (0/2) Documentation/kbuild: (0/4) Documentation/spi: (1/0) Documentation/virtual/kvm: (1/0) Documentation/scheduler: (0/2) Documentation/fb: (0/1) Documentation/block: (0/1) Documentation/networking: (6/37) Documentation/vm: (1/3) Then there are 364 subdirectories in Documentation/ with several files that are missing 00-INDEX alltogether (and another 120 with a single file and no 00-INDEX). I don't really have an opinion to whether or not we /should/ have 00-INDEX, but the above 00-INDEX should either be removed or be kept up to date. If we should keep the files, I can try to keep them updated, but I rather not if we just want to delete them anyway.

2017-01-29leds: class: Add new optional brightness_hw_changed attributeHans de Goede1-0/+15
Some LEDs may have their brightness level changed autonomously (outside of kernel control) by hardware / firmware. This commit adds support for an optional brightness_hw_changed attribute to signal such changes to userspace (if a driver can detect them): What: /sys/class/leds/<led>/brightness_hw_changed Date: January 2017 KernelVersion: 4.11 Description: Last hardware set brightness level for this LED. Some LEDs may be changed autonomously by hardware/firmware. Only LEDs where this happens and the driver can detect this, will have this file. This file supports poll() to detect when the hardware changes the brightness. Reading this file will return the last brightness level set by the hardware, this may be different from the current brightness. Drivers which want to support this, simply add LED_BRIGHT_HW_CHANGED to their flags field and call led_classdev_notify_brightness_hw_changed() with the hardware set brightness when they detect a hardware / firmware triggered brightness change.

2016-11-22leds: Introduce userspace LED class driverDavid Lechner1-0/+36
This driver creates a userspace leds driver similar to uinput. New LEDs are created by opening /dev/uleds and writing a uleds_user_dev struct. A new LED class device is registered with the name given in the struct. Reading will return a single byte that is the current brightness. The poll() syscall is also supported. It will be triggered whenever the brightness changes. Closing the file handle to /dev/uleds will remove the leds class device.

2016-09-27usb: core: Introduce a USB port LED triggerRafał Miłecki1-0/+41
This commit adds a new trigger responsible for turning on LED when USB device gets connected to the selected USB port. This can can useful for various home routers that have USB port(s) and a proper LED telling user a device is connected. The trigger gets its documentation file but basically it just requires enabling it and selecting USB ports (e.g. echo 1 > ports/usb1-1). There was a long discussion on design of this driver. Its current state is a result of picking them most adjustable solution as others couldn't handle all cases. 1) It wasn't possible for the driver to register separated trigger for each USB port. Some physical USB ports are handled by more than one controller and so by more than one USB port. E.g. USB 2.0 physical port may be handled by OHCI's port and EHCI's port. It's also not possible to assign more than 1 trigger to a single LED and implementing such feature would be tricky due to syncing triggers and sysfs conflicts with old triggers. 2) Another idea was to register trigger per USB hub. This wouldn't allow handling devices with multiple USB LEDs and controllers (hubs) controlling more than 1 physical port. It's common for hubs to have few ports and each may have its own LED. This final trigger is highly flexible. It allows selecting any USB ports for any LED. It was also modified (comparing to the initial version) to allow choosing ports rather than having user /guess/ proper names. It was successfully tested on SmartRG SR400ac which has 3 USB LEDs, 2 physical ports and 3 controllers. It was noted USB subsystem already has usb-gadget and usb-host triggers but they are pretty trivial ones. They indicate activity only and can't have ports specified. In future it may be good idea to consider adding activity support to usbport as well. This should allow switching to this more generic driver and maybe marking old ones as obsolete. This can be implemented with another sysfs file for setting mode. The default mode wouldn't change so there won't be ABI breakage and so such feature can be safely implemented later. There was also an idea of supporting other devices (PCI, SDIO, etc.) but as this driver already contains some USB specific code (and will get more) these should be probably separated drivers (triggers).

2016-09-15leds: add driver for Mellanox systems LEDsVadim Pasternak1-0/+110
This makes it possible to create a set of LEDs for Mellanox systems: "msx6710", "msx6720", "msb7700", "msn2700", "msx1410", "msn2410", "msb7800", "msn2740", "msn2100". Driver obtains LED devices according to system configuration, provided through system DMI data, like mlxcpld:fan1:green, mlxcpld:fan1:red and creates devices in form: "devicename:colour:function". LED setting is controlled through on board CPLD Lattice device. For setting particular LED off, solid, blink: echo 0 > /sys/class/leds/mlxcpld\:status\:green/brightness echo 1 > /sys/class/leds/mlxcpld\:status\:green/brightness echo timer > /sys/class/leds/mlxcpld\:status\:green/trigger On module probing all LEDs are set green, on removing - off. Last setting overwrites previous, f.e. sequence for changing LED from green - red - green: echo 1 > /sys/class/leds/mlxcpld\:psu\:green/brightness echo 1 > /sys/class/leds/mlxcpld\:psu\:red/brightness echo 1 > /sys/class/leds/mlxcpld\:psu\:green/brightness Note: LEDs cannot be turned on/off simultaneously.

2016-06-08leds: core: Fix brightness setting upon hardware blinking enabledTony Makkiel1-2/+2
Commit 76931edd54f8 ("leds: fix brightness changing when software blinking is active") changed the semantics of led_set_brightness() which according to the documentation should disable blinking upon any brightness setting. Moreover it made it different for soft blink case, where it was possible to change blink brightness, and for hardware blink case, where setting any brightness greater than 0 was ignored. While the change itself is against the documentation claims, it was driven also by the fact that timer trigger remained active after turning blinking off. Fixing that would have required major refactoring in the led-core, led-class, and led-triggers because of cyclic dependencies. Finally, it has been decided that allowing for brightness change during blinking is beneficial as it can be accomplished without disturbing blink rhythm. The change in brightness setting semantics will not affect existing LED class drivers that implement blink_set op thanks to the LED_BLINK_SW flag introduced by this patch. The flag state will be from now on checked in led_set_brightness() which will allow to distinguish between software and hardware blink mode. In the latter case the control will be passed directly to the drivers which apply their semantics on brightness set, which is disable the blinking in case of most such drivers. New drivers will apply new semantics and just change the brightness while hardware blinking is on, if possible. The issue was smuggled by subsequent LED core improvements, which modified the code that originally introduced the problem.

2015-06-11Input: export LEDs as class devices in sysfsSamuel Thibault1-3/+0
This change creates a new input handler called "leds" that exports LEDs on input devices as standard LED class devices in sysfs and allows controlling their state via sysfs or via any of the standard LED triggers. This allows to re-purpose and reassign LDEs on the keyboards to represent states other than the standard keyboard states (CapsLock, NumLock, etc). The old API of controlling input LEDs by writing into /dev/input/eventX devices is still present and will take precedence over accessing via LEDs subsystem (i.e. it may override state set by a trigger). If input device is "grabbed" then requests coming through LED subsystem will be ignored.

2014-01-27leds: lp5523: Support LED MUX configuration on running a patternMilo Kim1-1/+9
There are two ways to run a pattern in LP5523. One is using legacy sysfs files such as 'enginex_mode','enginex_load' and 'enginex_leds'. ('x' is from 1 to 3). Among them, 'enginex_leds' are used for selecting specific LED channel MUX. (MUX means which LEDs are used for running a pattern from LED 1 to 9.) The other way is using the firmware interface. In this mode, the default LED MUX strings are used. In other words, LED MUX is not configurable on the fly. This patch enables dynamic LED MUX configuration when the firmware is loaded. By accessing the sysfs file 'enginex_leds', the LED channels can be configured. To synchronize the operation mode, each engine mode should be set to 'LOAD'. The documentation is updated as well.
