From 0ecf24ef49d4f46ff5d6af357c3b9ec8d798160d Mon Sep 17 00:00:00 2001 From: Sonic Zhang Date: Mon, 20 Jul 2009 16:05:37 +0100 Subject: blackfin: fix wrong CTS inversion The Blackfin serial headers were inverting the CTS value leading to wrong handling of the CTS line which broke CTS/RTS handling completely.
