From 182cdcb8bb16e687dae9b03ac9ca9d80e873c076 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 22 Apr 2016 17:22:22 +0200 Subject: [PATCH] serial: mxs-auart: Use generic uart-has-rtscts DT property Convert the Freescale MXS AUART driver from using the vendor-specific "fsl,uart-has-rtscts" to the generic "uart-has-rtscts" DT property, as documented by the Generic Serial DT Bindings. The old vendor-specific property is still recognized by the driver for backwards compatibility, but it is deprecated.
