From a4f740cf33f7f6c164bbde3c0cdbcc77b0c4997c Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Sat, 30 Oct 2010 11:49:09 -0400 Subject: of/flattree: Add of_flat_dt_match() helper function This patch adds of_flat_dt_match() which tests a node for compatibility with a list of values and converts the relevant powerpc platform code to use it. This approach simplifies the board support code a bit.
