From 5a9ebe959967b7d3579de2a53d5df470fe0c7f22 Mon Sep 17 00:00:00 2001 From: Kim Phillips Date: Thu, 7 Jul 2011 14:43:12 -0500 Subject: dt: bindings: move SEC node under new crypto/ Since technically it's not powerpc arch-specific. Also rename it sec2 to differentiate it from its incompatible successor, the SEC 4.
