leds: leds-lp5569: Add support for Texas Instruments LP5569

2024-06-26T16:08:31+00:00

Add support for Texas Instruments LP5569 LED driver. Texas Instruments LP5569 is 9 channels chip with programmable engines. It almost a copy of LP5523 with fundamental changes to regs order and regs content. Has difference in how the clock is handled and doesn't support detecting clock time automatically, different handling for selftest and different scheme for the status regs. LED chip supports ENGINE and MUX to group LED and run precompiled code with magic values to run patterns. This is loaded via the sysfs entry and it's passed as a string of ASCII HEX char. One some devices using this LED Controller (a NBG7815 Router) it was found loading big precompiled pattern with up to 96 bytes of code. To have support for this "extended" scenario, hardcode each engine to support 4 pages of precompiled pattern (128 bytes of code) and 1 page for each MUX. This gives plenty of space for any kind precompiled pattern keeping simple logic for page handling of each engine and mux.

leds: Add ChromeOS EC driver

2024-06-21T10:41:46+00:00

The ChromeOS Embedded Controller exposes an LED control command. Expose its functionality through the leds subsystem. The LEDs are exposed as multicolor devices. A hardware trigger, which is active by default, is provided to let the EC itself take over control over the LED. The driver is designed to be probed via the cros_ec mfd device.

leds: Introduce ExpressWire library

2024-03-07T08:45:03+00:00

The ExpressWire protocol is shared between at least KTD2692 and KTD2801 with slight differences such as timings and the former not having a defined set of pulses for enabling the protocol (possibly because it does not support PWM unlike KTD2801). Despite these differences the ExpressWire handling code can be shared between the two, so in preparation for adding KTD2801 support introduce a library implementing this protocol.

leds: sun50i-a100: New driver for the A100 LED controller

2023-12-13T11:28:30+00:00

Some Allwinner sunxi SoCs, starting with the A100, contain an LED controller designed to drive RGB LED pixels. Add a driver for it using the multicolor LED framework, and with LEDs defined in the device tree.

leds: Fix config reference for AW200xx driver

2023-06-15T14:06:54+00:00

Commit 36a87f371b7a ("leds: Add AW20xx driver") adds config LEDS_AW200XX in drivers/leds/Kconfig, but then in drivers/leds/Makefile accidently refers to CONFIG_LEDS_W200XX; note the missing A! This typo makes it impossible to add the driver to a kernel build. Fix this wrong config reference.

leds: Add Intel Cherry Trail Whiskey Cove PMIC LED driver

2023-05-25T11:16:11+00:00

Add support for LEDs connected to the Intel Cherry Trail Whiskey Cove PMIC. Charger and general-purpose LEDs are supported. Hardware blinking is implemented, breathing is not. This driver was tested with Lenovo Yoga Book notebook. Changes by Hans de Goede (in response to review of v2): - Since the PMIC is connected to the battery any changes we make to the LED settings are permanent, even surviving reboot / poweroff. Save LED1 register settings on probe() and if auto-/hw-control was enabled on probe() restore the settings on remove() and shutdown(). - Delay switching LED1 to software control mode to first brightness write. - Use dynamically allocated drvdata instead of a global drvdata variable. - Ensure the LED is on when activating blinking. - Fix CHT_WC_LED_EFF_BREATHING val ((3 << 1) rather then BIT(3)).
