From 4ed10958ae461168be310b4bbee13f745e4c1547 Mon Sep 17 00:00:00 2001 From: Vlad Zakharov Date: Fri, 3 Mar 2017 14:30:01 +0300 Subject: [PATCH] ARC: [dts] add cpu nodes to ARCHS SMP device tree Trying to get clock for CPU cores on SMP systems I found that I was only able to get clock for core[0]. That was because only one cpu@0 node was represented in ARC HS device tree and it was impossible to get clock for "non-existing" cores. So as ARC HS may have up to 4 cores we update device tree to match maximum possible cores quantity.
