Hi Linus,
Please pull LED updates for 4.11 merge cycle.
New features and improvements:
- add new optional brightness_hw_changed attribute for the LEDs that
may have their brightness level changed autonomously, (outside of
kernel control) by hardware / firmware. The attribute supports
userspace notifications through POLLPRI events
- add led_brightness_hw_mon tool that demonstrates how to use the
aforementioned feature
- add LED_ON enum for LEDs that can be only turned on/off, and don't
allow setting other brightness levels
- allow for adjusting heartbeat trigger blink brightness level
Fixes and cleanups:
- avoid harmless maybe-uninitialized warning in leds-ktd2692.c
- add context to the existing example entries in common LED bindings
to make the documentation more clear
