Subject: [PATCH] dt-bindings: leds: Allow differently named multicolor leds

From: "J. Neuschäfer" <j.ne@...teo.net>

In some cases, a board may have multiple multi-leds, which can't be
distinguished by unit address. In such cases it should be possible to
name them differently, for example multi-led-a and multi-led-b.
This patch adds another node name pattern to leds-class-multicolor.yaml
to allow such names.
