leds: Introduce ExpressWire library

2024-03-07T08:45:03Z

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

2023-12-13T11:28:30Z

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

2023-06-15T14:06:54Z

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

2023-05-25T11:16:11Z

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)).
