Message-Id: <1521447194-26514-1-git-send-email-hayashi.kunihiko@socionext.com>
Date: Mon, 19 Mar 2018 17:13:14 +0900
From: Kunihiko Hayashi <hayashi.kunihiko@...ionext.com>
To: linux-gpio@...r.kernel.org,
Linus Walleij <linus.walleij@...aro.org>,
Masahiro Yamada <yamada.masahiro@...ionext.com>

Subject: [PATCH] pinctrl: uniphier: add UART hardware flow control pin-mux settings
UniPhier SoCs have the following pins for hardware flow control of UART:
XRTS, XCTS
and for modem control of UART:
XDTR, XDSR, XDCD, XRI
The port number with the flow control is SoC-dependent.
Signed-off-by: Kunihiko Hayashi <hayashi.kunihiko@...ionext.com>
