From da5d01f23bc1ff710797a563ca3616df95395a12 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 6 Oct 2012 00:11:16 +0100 Subject: [PATCH] SERIAL: omap: allow hardware assisted IXANY mode to be disabled Nothing was clearing the UART_MCR_XONANY bit, so once the ixany mode gets set, there's no possibility to disable it. Clear this bit when IXANY mode is cleared.
