From bb28eb3797b0fbb4baa6d87edf69b3a0ff499e94 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 18 May 2012 01:53:01 +0200 Subject: [PATCH] dt: add helper for 64bit cell adds Some times in the device tree, we find an array of 2 u32 cells that really are a single u64 value. This patch adds a helper to make the creation of these easy.
