The patches should apply on Pavel's for-next branch. Changes since RFC: - added device-tree bindings documentation - the reg property is abandoned, as discussed previously on mailing list, since it can be deduced from led-sources - setting devicename is dropped After a call with Pavel I decided that it would be good to first merge this driver in this state, and then work on improving it, eg: - adding support for changing global brightness via sysfs file as discussed previously - adding support for proper device name (the first part of the sysfs name for the LED classdev). The best way to connect a LED to a device (for example a network interface) is via a phandle in device tree (utilizing trigger-sources, for example). This could be implemented as a LED subsystem library function and then used by drivers Marek Marek Behún (2): dt-bindings: leds: add cznic,turris-omnia-leds binding leds: initial support for Turris Omnia LEDs .../leds/cznic,turris-omnia-leds.yaml | 113 +++++++ MAINTAINERS | 6 +- drivers/leds/Kconfig | 11 + drivers/leds/Makefile | 1 + drivers/leds/leds-turris-omnia.c | 285 ++++++++++++++++++ 5 files changed, 414 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/leds/cznic,turris-omnia-leds.yaml create mode 100644 drivers/leds/leds-turris-omnia.c
