14 ----------
16 There are two distinct ways to configure the frame size produced by camera
23 processing pipeline as one or more sub-devices with different cropping and
40 Frame interval configuration
41 ----------------------------
43 There are two different methods for obtaining possibilities for different frame
44 intervals as well as configuring the frame interval. Which one to implement
50 Instead of a high level parameter such as frame interval, the frame interval is
55 The frame interval is calculated using the following equation::
57 	frame interval = (analogue crop width + horizontal blanking) *
68 sub-device. The unit of that control is pixels per second.
70 Register list based drivers need to implement read-only sub-device nodes for the
83 level interface natively, generally use the concept of frame interval (or frame
86 frame interval on these devices.
