From 35c3017a29d278c4405a7f3ab30b814999d156d3 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 5 May 2010 11:38:35 -0300 Subject: [media] v4l: v4l2_subdev userspace frame interval API The three new ioctl VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL, VIDIOC_SUBDEV_G_FRAME_INTERVAL and VIDIOC_SUBDEV_S_FRAME_INTERVAL can be used to enumerate and configure a subdev's frame rate from userspace. Two new video::g/s_frame_interval subdev operations are introduced to support those ioctls. The existing video::g/s_parm operations are deprecated and shouldn't be used anymore.
