From 3daf37260e965aa4bb060db99c2ed10b28109e04 Mon Sep 17 00:00:00 2001 From: Tony Prisk Date: Sat, 23 Mar 2013 17:02:15 +1300 Subject: of: Add support for reading a u32 from a multi-value property. This patch adds an of_property_read_u32_index() function to allow reading a single indexed u32 value from a property containing multiple u32 values.
