From 105fc00bc388d2dff089f3330fc7d9b009c519dc Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Fri, 3 Feb 2017 10:23:16 +0000 Subject: ARM: dts: STiH410-b2260: Identify the UART RTS line When hardware flow-control is disabled, manual toggling of the UART's reset line (RTS) using userland applications (e.g. stty) is not possible, since the ASC IP does not provide this functionality in the same was as some other IPs do. Thus, we have to do this manually. This patch configures the UART RTS line as a GPIO for manipulation within the UART driver when HW flow-control is not enabled.
