From 8a30b4700942f37495d2e67f5998cdffb6e3ba8a Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sun, 24 Feb 2008 23:52:35 -0500 Subject: [PATCH] smc91111: use SSYNC() rather than asm(ssync) for Blackfin Since the "ssync" instruction may have hardware anomalies associated with it, have the smc91111 driver use the SSYNC macro rather than invoking it directly. We workaround all the anomalies via this macro.
