Subject: [RESENT PATCH V0 2/4] media: subdev: support which in v4l2_subdev_frame_interval
Date: Fri, 7 May 2021 15:46:02 +0800 [thread overview]
Message-ID: <20210507074604.15079-3-louis.kuo@mediatek.com> (raw)
In-Reply-To: <20210507074604.15079-1-louis.kuo@mediatek.com>
This patch is to support try or set of VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL
through which parameter.
This behavior is already supported in some similar V4L2 IOCTLs such as
VIDIOC_SUBDEV_ENUM_FRAME_SIZE for the same reason.
Signed-off-by: Louis Kuo <louis.kuo@mediatek.com>
