leds: Fix ifdef check for gpio_led_register_device()

2024-03-07T08:48:14Z

gpio_led_register_device() is built whenever CONFIG_LEDS_GPIO_REGISTER is enabled, and this may be used even when CONFIG_NEW_LEDS is turned off. However, the stub declaration in the header is provided for all configs without CONFIG_NEW_LEDS, resulting in a build failure: drivers/leds/leds-gpio-register.c:24:1: error: redefinition of 'gpio_led_register_device' 24 | gpio_led_register_device(int id, const struct gpio_led_platform_data *pdata) | ^ include/linux/leds.h:646:39: note: previous definition is here Change the #ifdef check to match the definition. Note: this apparently took years of randconfig builds to hit, since a number of other drivers just 'select NEW_LEDS' anyway.

leds: Remove led_init_default_state_get() and devm_led_classdev_register_ext() stubs

2024-03-07T08:48:02Z

These two functions have stub implementations that are called when NEW_LEDS and/or LEDS_CLASS are disabled, theorerically allowing drivers to optionally use the LED subsystem. However, this has never really worked because a built-in driver is unable to link against these functions if the LED class is in a loadable module. Heiner ran into this problem with a driver that newly gained a LEDS_CLASS dependency and suggested using an IS_REACHABLE() check. This is the reverse approach, removing the stub entirely to acknowledge that it is pointless in its current form, and that not having it avoids misleading developers into thinking that they can rely on it. This survived around 1000 randconfig builds to validate that any callers of the interface already have the correct Kconfig dependency already, with the exception of the one that Heiner just added.

leds: trigger: netdev: add additional specific link duplex mode

2023-06-21T21:30:46Z

Add additional modes for specific link duplex. Use ethtool APIs to get the current link duplex and enable the LED accordingly. Under netdev event handler the rtnl lock is already held and is not needed to be set to access ethtool APIs. This is especially useful for PHY and Switch that supports LEDs hw control for specific link duplex. Add additional modes: - half_duplex: Turn on LED when link is half duplex - full_duplex: Turn on LED when link is full duplex Signed-off-by: Christian Marangi Reviewed-by: Andrew Lunn Acked-by: Lee Jones Signed-off-by: Jakub Kicinski

leds: trigger: netdev: add additional specific link speed mode

2023-06-21T21:30:46Z

Add additional modes for specific link speed. Use ethtool APIs to get the current link speed and enable the LED accordingly. Under netdev event handler the rtnl lock is already held and is not needed to be set to access ethtool APIs. This is especially useful for PHY and Switch that supports LEDs hw control for specific link speed. (example scenario a PHY that have 2 LED connected one green and one orange where the green is turned on with 1000mbps speed and orange is turned on with 10mpbs speed) On mode set from sysfs we check if we have enabled split link speed mode and reject enabling generic link mode to prevent wrong and redundant configuration. Rework logic on the set baseline state to support these new modes to select if we need to turn on or off the LED. Add additional modes: - link_10: Turn on LED when link speed is 10mbps - link_100: Turn on LED when link speed is 100mbps - link_1000: Turn on LED when link speed is 1000mbps Signed-off-by: Christian Marangi Reviewed-by: Andrew Lunn Acked-by: Lee Jones Signed-off-by: Jakub Kicinski
