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!

2023-05-25leds: Add Intel Cherry Trail Whiskey Cove PMIC LED driverYauhen Kharuzhy1-0/+1
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)).

2022-05-04leds: Add driver for Qualcomm LPGBjorn Andersson1-0/+3
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.

2018-02-19leds: add driver for support Mellanox regmap LEDs for BMC and x86 platformVadim Pasternak1-0/+1
Driver obtains LED devices according to system configuration and creates devices in form: "devicename:color:function", like The full path is to be: /sys/class/leds/mlxreg\:status\:amber/brightness After timer trigger activation: echo timer > /sys/class/leds/mlxreg\:status\:amber/trigger Attributes for LED blinking will appaer in sysfs infrastructure: /sys/class/leds/mlxreg\:status\:amber/delay_off /sys/class/leds/mlxreg\:status\:amber/delay_on LED setting is controlled through the on-board programmable devices, which exports its register map. This device could be attached to any bus type, for which register mapping is supported.
