This function was added with a8df7b1ab70b ("leds: add led_trigger_rename function") 11 yrs ago, but it has no users. So remove it. Signed-off-by: Heiner Kallweit Link: https://lore.kernel.org/r/d90f30be-f661-4db7-b0b5-d09d07a78a68@gmail.com Signed-off-by: Lee Jones

leds: class: Store the color index in struct led_classdev

2023-08-17T08:00:34Z

Store the color of the LED so that it is not lost after the LED's name has been composed. This color information can then be exposed to the user space or used by the LED consumer.

leds: Provide devm_of_led_get_optional()

2023-08-17T08:00:06Z

Add an optional variant of devm_of_led_get(). It behaves the same as devm_of_led_get() except where the LED doesn't exist. In this case, instead of returning -ENOENT, the function returns NULL.

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

leds: add API to get attached device for LED hw control

2023-05-31T08:42:08Z

Some specific LED triggers blink the LED based on events from a device or subsystem. For example, an LED could be blinked to indicate a network device is receiving packets, or a disk is reading blocks. To correctly enable and request the hw control of the LED, the trigger has to check if the network interface or block device configured via a /sys/class/led file match the one the LED driver provide for hw control for. Provide an API call to get the device which the LED blinks for. Signed-off-by: Andrew Lunn Signed-off-by: Christian Marangi Signed-off-by: David S. Miller

leds: add APIs for LEDs hw control

2023-05-31T08:42:08Z

Add an option to permit LED driver to declare support for a specific trigger to use hw control and setup the LED to blink based on specific provided modes. Add APIs for LEDs hw control. These functions will be used to activate hardware control where a LED will use the provided flags, from an unique defined supported trigger, to setup the LED to be driven by hardware. Add hw_control_is_supported() to ask the LED driver if the requested mode by the trigger are supported and the LED can be setup to follow the requested modes. Deactivate hardware blink control by setting brightness to LED_OFF via the brightness_set() callback. Signed-off-by: Christian Marangi Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller
