From 84130aace83989c1dba073ed98dad721d2060258 Mon Sep 17 00:00:00 2001 From: Richard Genoud Date: Tue, 13 May 2014 20:20:43 +0200 Subject: tty/serial: Add GPIOLIB helpers for controlling modem lines This patch add some helpers to control modem lines (CTS/RTS/DSR...) via GPIO. This will be useful for many boards which have a serial controller that only handle CTS/RTS pins (or even just RX/TX).
