Subject: [RESENT PATCH V0 3/4] media: v4l2-ctrl: Add ISP Camsys user control
Date: Fri, 7 May 2021 15:46:03 +0800	[thread overview]
Message-ID: <20210507074604.15079-4-louis.kuo@mediatek.com> (raw)
In-Reply-To: <20210507074604.15079-1-louis.kuo@mediatek.com>

This patch is to add V4L2_CID_USER_MTK_CAM_BASE for Mediatek ISP-only
features. For example, we have some hits from user to let driver select
internal path and resource usage.
(e.g. use multiple engine or bining the image or use higher clk and power).
