+OMAP3 GPTIMER: TOCR clears sometimes require two writes
+
+From: Paul Walmsley <paul@pwsan.com>
+
+Some GPTIMER register changes do not take effect with a single write;
+they require two writes for some reason.  Could be related to the
+existing 3430 errata "GPTimer 1,2, and 10: first write access to TCRR
+register discarded"
