From: Geert Uytterhoeven Date: Fri, 22 Apr 2016 15:22:24 +0000 (+0200) Subject: serial: sirf: Use generic uart-has-rtscts DT property X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7f60830ab1511d9449ac60ba4591fe3730445587;p=linux-beck.git serial: sirf: Use generic uart-has-rtscts DT property Convert the SiRF UART driver from using the vendor-specific "sirf,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 deprecated.
