Subject: [PATCH v1 07/15] drm/mediatek: add layer config to set RDMA for plane setting
Date: Tue, 24 Jul 2018 16:17:07 +0800 [thread overview]
Message-ID: <1532420235-22268-8-git-send-email-stu.hsieh@mediatek.com> (raw)
In-Reply-To: <1532420235-22268-1-git-send-email-stu.hsieh@mediatek.com>
This patch add layer config to set RDMA for plane setting
Layer config set the data address and pitch to RDMA from plane setting.
