From ca3e442e8dbbe2551473f36f0e7797b1d3205f5a Mon Sep 17 00:00:00 2001 From: Graf Yang Date: Sun, 23 May 2010 04:40:13 -0400 Subject: serial: bfin_5xx: IRDA is not affected by anomaly 05000230 Anomaly 05000230 (over sampling of the UART STOP bit) applies only when the peripheral is operating in UART mode. So drop the anomaly handling when the UART is in IRDA mode.
