leds: pca995x: Add support for PCA995X chips

2023-07-28T08:26:28+00:00

The PCA995x chips are I2C controlled LED drivers. Each chip has up to 16 outputs, each one with an individual 8-bit resolution PWM for brightness control.

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)).

2023-04-27T16:42:33+00:00

The device provides 6 channels which can be individually turned off and on but groups of two channels share a common brightness register. Limitation: The GPIO to enable the device is not used yet.
