From 0c529b3fc6c66e618088aa3a998d760d1ad05272 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 3 Jun 2016 12:00:01 +0200 Subject: [PATCH] serial: sh-sci: Update DT binding documentation for GPIO modem lines Amend the DT bindings for the Renesas SCI driver to allow describing optional GPIO-controlled modem lines, which can be used where dedicated modem lines are not available. The property naming is dictated by the Generic Serial DT Bindings.
