be2f9284 - leds: Kconfig: leds-st1202: Add select for required LEDS_TRIGGER_PATTERN

Wed, 26 Feb 2025 17:12:50 +0000

leds: Kconfig: leds-st1202: Add select for required LEDS_TRIGGER_PATTERNleds-st1202 requires the LED Pattern Trigger (LEDS_TRIGGER_PATTERN), whichis not selected when LED Trigger support is (LEDS_TRIGGERS).To reproduce this:- make menuconfig KCONFIG_CONFIG=- select LEDS_ST1202 dependencies OF, I2C and LEDS_CLASS.- select LEDS_ST1202- LEDS_TRIGGERS is selected but LEDS_TRIGGER_PATTERN isn't.The absence of LEDS_TRIGGER_PATTERN explicitly required can lead to buildsin which LEDS_ST1202 is selected while LEDS_TRIGGER_PATTERN isn't. The directresult of that would be that /sys/class/leds//hw_pattern wouldn't beavailable and there would be no way of interacting with the driver andhardware from user space.Add select LEDS_TRIGGER_PATTERN to Kconfig to meet the requirement andindirectly document it as well.Signed-off-by: Manuel Fombuena Link: https://lore.kernel.org/r/CWLP123MB5473F4DF3A668F7DD057A280C5C22@CWLP123MB5473.GBRP123.PROD.OUTLOOK.COMSigned-off-by: Lee Jones List of files: /linux-6.15/drivers/leds/Kconfig

TheLED1202 implements 12 low-side current generators with independent dimmingcontrol.Internal volatile memory allows the user to store up to 8 different patterns,each pattern is a particular output configuration in terms of PWMduty-cycle (on 4096 steps). Analog dimming (on 256 steps) is per channel butcommon to all patterns. Each device tree LED node will have a correspondingentry in /sys/class/leds with the label name.

Mon, 11 Nov 2024 10:03:51 +0000

leds: turris-omnia: Notify sysfs on MCU global LEDs brightness changeRecall that on Turris Omnia, the LED controller has a global brightnessproperty, which allows the user to make the front LED panel dimmer.There is also a button on the front panel, which by default isconfigured so that pressing it changes the global brightness to a lowervalue (unless it is at 0%, in which case pressing the button changes theglobal brightness to 100%).Newer versions of the MCU firmware support informing the SOC that thebrightness was changed by button press event via an interrupt.Now that we have the turris-omnia-mcu driver, which adds support for MCUinterrupts, add the ability to inform the userspace (via a sysfsnotification) that the global brightness was changed.Signed-off-by: Marek Behún Link: https://lore.kernel.org/r/20241111100355.6978-8-kabel@kernel.orgSigned-off-by: Lee Jones List of files: /linux-6.15/drivers/leds/Kconfig

56e8c56c - leds: Add multicolor support to BlinkM LED driver

Wed, 10 Jul 2024 18:48:44 +0000

leds: Add multicolor support to BlinkM LED driverAdd multicolor support to the BlinkM driver, making it easier to controlfrom userspace. The BlinkM LED is a programmable RGB LED. The drivercurrently supports only the regular LED sysfs class, resulting in thecreation of three distinct classes, one for red, green, and blue. Theuser then has to input three values into the three seperate brightnessfiles within those classes. The multicolor LED framework makes thedevice easier to control with the multi_intensity file: the user caninput three values at once to form a color, while still controlling thelightness with the brightness file.The main struct blinkm_led has changed slightly. The struct led_classdevfor the regular sysfs classes remain. The blinkm_probe function checksCONFIG_LEDS_BLINKM_MULTICOLOR to decide whether to load the seperatesysfs classes or the single multicolor one, but never both. Theblinkm_set_mc_brightness() function had to be added to calculate thethree color components and then set the fields of the blinkm_datastructure accordingly.Signed-off-by: Joseph Strauss Link: https://lore.kernel.org/r/20240710184844.108006-1-jstrauss@mailbox.orgSigned-off-by: Lee Jones List of files: /linux-6.15/drivers/leds/Kconfig

This is loaded via the sysfs entryand it's passed as a string of ASCII HEX char.One some devices using this LED Controller (a NBG7815 Router) it wasfound loading big precompiled pattern with up to 96 bytes of code. Tohave support for this "extended" scenario, hardcode each engine tosupport 4 pages of precompiled pattern (128 bytes of code) and 1 pagefor each MUX. This gives plenty of space for any kind precompiledpattern keeping simple logic for page handling of each engine and mux.Signed-off-by: Christian Marangi Link: https://lore.kernel.org/r/20240626160027.19703-21-ansuelsmth@gmail.comSigned-off-by: Lee Jones List of files: /linux-6.15/drivers/leds/Kconfig
