Subject: [PATCH v2 22/22] pinctrl: mediatek: add eint support to MT8183 pinctrl driver
Date: Sat, 8 Sep 2018 19:07:38 +0800 [thread overview]
Message-ID: <17745498577a9d4492deee861d71a135de5b8473.1536404280.git.sean.wang@mediatek.com> (raw)
In-Reply-To: <cover.1536404280.git.sean.wang@mediatek.com>
From: Sean Wang <sean.wang@mediatek.com>
Just add eint support to MT8183 pinctrl driver as usual as
happens on the other SoCs.
