1config USB_SN9C102
2 tristate "USB SN9C1xx PC Camera Controller support (DEPRECATED)"
3 depends on VIDEO_V4L2
4 ---help---
5 This driver is DEPRECATED please use the gspca sonixb and
6 sonixj modules instead.
7
8 Say Y here if you want support for cameras based on SONiX SN9C101,
9 SN9C102, SN9C103, SN9C105 and SN9C120 PC Camera Controllers.
10
11 See <file:Documentation/video4linux/sn9c102.txt> for more info.
12
13 To compile this driver as a module, choose M here: the
14 module will be called sn9c102.

37 OVERVIEW.
38 This is a small interface that allows you to add support for any CCD/CMOS
39 image sensors connected to the SN9C1XX bridges. The entire API is documented
40 below. In the most general case, to support a sensor there are three steps
41 you have to follow:
42 1) define the main "sn9c102_sensor" structure by setting the basic fields;
43 2) write a probing function to be called by the core module when the USB
44 camera is recognized, then add both the USB ids and the name of that
45 function to the two corresponding tables in sn9c102_devtable.h;
46 3) implement the methods that you want/need (and fill the rest of the main
47 structure accordingly).
48 "sn9c102_pas106b.c" is an example of all this stuff. Remember that you do
49 NOT need to touch the source code of the core module for the things to work
50 properly, unless you find bugs or flaws in it. Finally, do not forget to
51 read the V4L2 API for completeness.

95 writes n bytes, from data0 to datan, to registers 0x09 - 0x09+n of SN9C1XX
96 chip. The second one programs the registers 0x09 and 0x10 with data0 and
97 data1, and places the n bytes read from the sensor register table in the

214 the complete array of pixels, from (0,0) to (xmax, ymax). We will
215 use this coordinate system from now on. It is assumed the sensor
216 chip can be programmed to capture/transmit a subsection of that
217 array of pixels: we will call this subsection "active window".
218 It is not always true that the largest achievable active window can
219 cover the whole array of pixels. The V4L2 API defines another
220 area called "source rectangle", which, in turn, is a subrectangle of
221 the active window. The SN9C1XX chip is always programmed to read the
222 source rectangle.
223 The bounds of both the active window and the source rectangle are
224 specified in the cropcap substructures 'bounds' and 'defrect'.
225 By default, the source rectangle should cover the largest possible
226 area. Again, it is not always true that the largest source rectangle
227 can cover the entire active window, although it is a rare case for
228 the hardware we have. The bounds of the source rectangle _must_ be
229 multiple of 16 and must use the same coordinate system as indicated
230 before; their centers shall align initially.
231 If necessary, the sensor chip must be initialized during init() to
232 set the bounds of the active sensor window; however, by default, it
233 usually covers the largest achievable area (maxwidth x maxheight)
234 of pixels, so no particular initialization is needed, if you have
235 defined the correct default bounds in the structures.
236 See the V4L2 API for further details.
237 NOTE: once you have defined the bounds of the active window
238 (struct cropcap.bounds) you must not change them.anymore.
239 Only 'bounds' and 'defrect' fields are mandatory, other fields
240 will be ignored.

250 case you override the default function, you always have to program
251 the chip to match those values; on error return the corresponding
252 error code without rolling back.
253 NOTE: in case, you must program the SN9C1XX chip to get rid of
