From mboxrd@z Thu Jan 1 00:00:00 1970 From: Rob Herring Date: Sun, 2 Dec 2012 21:09:26 -0600 Subject: [U-Boot] [PATCH] serial_pl011: Set RTS during initialization Message-ID: <1354504166-1946-1-git-send-email-robherring2@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: Joshua Housh 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.
