From mboxrd@z Thu Jan 1 00:00:00 1970 From: Geert Uytterhoeven Subject: [PATCH/RFC 1/5] serial: sh-sci: Update DT binding documentation for GPIO modem lines Date: Thu, 17 Mar 2016 14:47:25 +0100 Message-ID: <1458222449-12324-2-git-send-email-geert+renesas@glider.be> References: <1458222449-12324-1-git-send-email-geert+renesas@glider.be> Return-path: In-Reply-To: <1458222449-12324-1-git-send-email-geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org> Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Greg Kroah-Hartman , Jiri Slaby , Peter Hurley , Magnus Damm Cc: Laurent Pinchart , Yoshinori Sato , linux-serial-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-renesas-soc-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-sh-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Geert Uytterhoeven , devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: devicetree@vger.kernel.org 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 SERIAL_MCTRL_GPIO helpers.
