* leds: Make LEDS_TI_LMU_COMMON invisibleGeert Uytterhoeven2023-05-251-6/+5
| | | | | | | | | | | | | | | Currently, LEDS_LM3697 and LEDS_LM36274 depend on LEDS_TI_LMU_COMMON, which contains the common code to support TI LMU devices. This means the user is asked about the common code first, followed by the individual drivers, if their dependencies are met. Simplify this, and reduce the number of questions by making LEDS_TI_LMU_COMMON invisible, and letting it be selected when needed.

* leds: Add Intel Cherry Trail Whiskey Cove PMIC LED driverYauhen Kharuzhy2023-05-251-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | 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)).

* leds: TI_LMU_COMMON: select REGMAP instead of depending on itRandy Dunlap2023-03-161-1/+1
| | | | | | | | | | | | | | | | | REGMAP is a hidden (not user visible) symbol. Users cannot set it directly thru "make *config", so drivers should select it instead of depending on it if they need it. Consistently using "select" or "depends on" can also help reduce Kconfig circular dependency issues. Therefore, change the use of "depends on REGMAP" to "select REGMAP".

* leds: Add driver for Qualcomm LPGBjorn Andersson2022-05-041-0/+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.

* leds: initial support for Turris Omnia LEDsMarek Behún2020-07-241-0/+11
| | | | | | | | | | | | | | | This adds basic support for LEDs on the front side of CZ.NIC's Turris Omnia router. There are 12 RGB LEDs. The controller supports HW triggering mode for the LEDs, but this driver does not support it yet, and sets all the LEDs defined in device-tree into SW mode upon probe. This driver uses the multicolor LED framework. Signed-off-by: Marek Behún <marek.behun@nic.cz> Reviewed-by: Dan Murphy <dmurphy@ti.com> Signed-off-by: Pavel Machek <pavel@ucw.cz>

* leds: multicolor: Introduce a multicolor class definitionDan Murphy2020-07-221-0/+10
| | | | | | | | | | | | | | | Introduce a multicolor class that groups colored LEDs within a LED node. The multicolor class groups monochrome LEDs and allows controlling two aspects of the final combined color: hue and lightness. The former is controlled via the intensity file and the latter is controlled via brightness file.

* leds: apu: drop superseeded apu2/3 led supportEnrico Weigelt2019-07-221-1/+4
| | | | | | | | | | | | | | | | | | | | | | This driver only supports gpio-attached LEDs on apu1/2/3 boards, but neither gpio's themselves, nor other gpio-attached devices (eg. front button). For apu2+ a newer, more complete driver exists, based on a generic driver for the AMD SOCs gpio-controller, supporting LEDs as well other devices. Therefore these boards don't need legacy support from this driver anymore. Both drivers claim the same device, so only one driver may exist in a system, putting distros in the position to decide between either apu2+ keys or apu1 led support. Therefore drop the apu2+ led support from the old driver, solve the conflict and reduce unnecessary code.
