From a8c759c78f709a8c0642a67debf88ec597d74757 Mon Sep 17 00:00:00 2001 From: yangbo lu Date: Wed, 9 Nov 2016 11:14:07 +0800 Subject: dt: bindings: move guts devicetree doc out of powerpc directory Move guts devicetree doc to Documentation/devicetree/bindings/soc/fsl/ since it's used by not only PowerPC but also ARM. And add a specification for 'little-endian' property.
