From fbb18a277a6f192404aa20ece49529acb1e1e76d Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 26 Mar 2006 23:13:39 +0100 Subject: [SERIAL] amba-pl010: allow platforms to specify modem control method The amba-pl010 hardware does not provide RTS and DTR control lines; it is expected that these will be implemented using GPIO. Allow platforms to supply a function to implement manipulation of modem control lines.
