From d50701781a55d09696a0585112a124b0723acf3b Mon Sep 17 00:00:00 2001 From: Matthias Fuchs Date: Tue, 30 Dec 2008 00:59:38 +0000 Subject: [PATCH] powerpc: Add ioctls for RS485 mode control of serial drivers These ioctls take a struct serial_rs485 (see linux/serial.h) as argument. They are already available on x86. This patch adds them for the powerpc architecture.
