From 45a14984163349d8ea4db1463322944e54e7ce54 Mon Sep 17 00:00:00 2001
From: Dmitry Shifrin <dmitry.shifrin@cogentembedded.com>
Date: Mon, 19 Nov 2018 20:30:06 +0300
Subject: [PATCH 070/211] pinctrl: sh-pfc: r8a77980: Add QSPI pins, groups, and
 functions

Add the QSPI{0|1} pins/groups/functions to the R8A77980 PFC driver.

[Sergei: ported to the upstream driver, fixed up the swapped QSPI0 SPCLK/
SSL pins, fixed up the comments, moved the QSPI pins/groups/functions to
be in the alphanumeric order, removed unneeded empty lines, renamed the
patch.]
