Subject: [PATCH 4/5] dt-bindings: i2c: Add Mediatek MT8183 i2c binding
Date: Mon, 3 Dec 2018 21:32:53 +0800 [thread overview]
Message-ID: <1543843974-4054-5-git-send-email-qii.wang@mediatek.com> (raw)
In-Reply-To: <1543843974-4054-1-git-send-email-qii.wang@mediatek.com>
From: qii wang <qii.wang@mediatek.com>
Add MT8183 i2c binding to binding file. Compare to 2712 i2c
controller, MT8183 has different registers, offsets, clock,
and multi-user function.
