leds: aw2013: Select missing dependency REGMAP_I2C

2024-01-25T23:35:49+00:00

[ Upstream commit 75469bb0537ad2ab0fc1fb6e534a79cfc03f3b3f ] The AW2013 driver uses devm_regmap_init_i2c, so REGMAP_I2C needs to be selected. Otherwise build process may fail with: ld: drivers/leds/leds-aw2013.o: in function `aw2013_probe': leds-aw2013.c:345: undefined reference to `__devm_regmap_init_i2c' Signed-off-by: Dang Huynh Acked-by: Nikita Travkin Fixes: 59ea3c9faf32 ("leds: add aw2013 driver") Link: https://lore.kernel.org/r/20231103114203.1108922-1-danct12@riseup.net Signed-off-by: Lee Jones Signed-off-by: Sasha Levin

leds: Add HAS_IOPORT dependencies

2023-05-25T11:20:47+00:00

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends not being declared. We thus need to add HAS_IOPORT as dependency for those drivers using them.

leds: Make LEDS_TI_LMU_COMMON invisible

2023-05-25T11:16:21+00:00

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 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)).

leds: TI_LMU_COMMON: select REGMAP instead of depending on it

2023-03-16T15:08:38+00:00

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".
