From 0e373639ad7c7ef2b0c9cf907574b266791b9778 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 6 Jul 2011 15:42:58 -0500 Subject: dt: add helper function to read u32 arrays Rework of_property_read_u32 to read an array of values. Then of_property_read_u32 becomes an inline with array size of 1. Also make struct device_node ptr const.
