From f041f96abcf8718540e94aac6e73604c5d33d9f9 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Wed, 27 Jun 2018 20:52:33 +0200 Subject: dt-bindings: leds: Add bindings for lltc,lt3593 This patch adds the bindings document for LT3593 LED drivers. The binding is kept consistent with other LED driver bindings in that it stores all the LED-specific properties in its own subnode. As the hardware only supports one channel, there can consequently only be one sub-node.
