From d3dec96e401cc66d7280732558d711ac2ee7a531 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Mon, 27 Aug 2012 16:03:14 +0200 Subject: tty: serial: mpc5xxx: add support for mark/space parity Tested on a custom MPC5200B-board using some fancy industrial protocol. Verified that MPC512x has identical bits, so should work there as well.
