Merge tag 'leds-for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
Pull LED updates from Jacek Anaszewski: "We introduce LED pattern trigger - the idea that was proposed three years ago now received enough attention and determination to drive it to the successful end. There is also one new LED class driver and couple of improvements to the existing ones. New LED class driver: - add support for Panasonic AN30259A with related DT bindings New LED trigger: - introduce LED pattern trigger leds-sc27xx-bltc: - implement pattern_set/clear ops to enable support for pattern trigger's hw_pattern sysfs file Improvements to existing LED class drivers: - leds-pwm: don't print error message on -EPROBE_DEFER - leds-gpio: try to lookup gpiod from device - leds-as3645a: convert to using %pOFn instead of device_node.name" * tag 'leds-for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds: leds: sc27xx: Add pattern_set/clear interfaces for LED controller leds: core: Introduce LED pattern trigger leds: add Panasonic AN30259A support dt-bindings: leds: document Panasonic AN30259A bindings leds: gpio: Try to lookup gpiod from device leds: pwm: silently error out on EPROBE_DEFER leds: Convert to using %pOFn instead of device_node.name
