From 10501df05e2d2eef501c92483c134d5f7c9da150 Mon Sep 17 00:00:00 2001 From: Joshua Housh Date: Sun, 2 Dec 2012 17:09:26 +0000 Subject: [PATCH] serial_pl011: Set RTS during initialization If the pl011 is connected to another device which has hardware flow-control on, characters are never received by the pl011. Asserting RTS when flow-control is off will have no effect. This is in line with how Linux behaves.
