From 75f9f7279e874ff95d1abe4613abc0826c9a8dcc Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Fri, 22 Sep 2017 12:32:36 +0300 Subject: dt: bindings: as3645a: Use LED number to refer to LEDs Use integers (reg property) to tell the number of the LED to the driver instead of the node name. While both of these approaches are currently used by the LED bindings, using integers will require less driver changes for ACPI support. Additionally, it will make possible LED naming using chip and LED node names, effectively making the label property most useful for human-readable names only.
