[PATCH v2 1/3] dt-bindings: leds: common: Drop enumeration for linux,default-triggers

From: Chen-Yu Tsai
Date: Mon Apr 27 2020 - 03:31:47 EST


From: Chen-Yu Tsai <wens@xxxxxxxx>

The bindings currently list a very small subset of valid triggers for
LEDs. Since many drivers or subsystems in Linux register custom
triggers, the list would become very hard to maintain.

Instead, just drop the list and allow free form strings.
