From f67605394f0ba44cff297120fda6bb407414ba75 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Thu, 6 Dec 2012 09:53:13 +0000 Subject: devicetree/bindings: Move gpio-leds binding into leds directory Merely reorganizing documentation. No functional changes. It makes more sense for the gpio-leds binding to be grouped with other led bindings than with gpio drivers.
