Driver for Linux

4. Overview and features
========================
This driver attempts to support the video interface of the devices mounting the
SONiX SN9C101, SN9C102 and SN9C103 PC Camera Controllers.
It's worth to note that SONiX has never collaborated with the author during the
development of this project, despite several requests for enough detailed
specifications of the register tables, compression engine and video data format
of the above chips. Nevertheless, these informations are no longer necessary,
because all the aspects related to these chips are known and have been
described in detail in this documentation.
This driver attempts to support the video interface of the devices assembling
the SONiX SN9C101, SN9C102, SN9C103, SN9C105 and SN9C120 PC Camera Controllers
("SN9C1xx" from now on).
The driver relies on the Video4Linux2 and USB core modules. It has been
designed to run properly on SMP systems as well.
The latest version of the SN9C10x driver can be found at the following URL:

6. Module loading
=================
To use the driver, it is necessary to load the "sn9c102" module into memory
after every other module required: "videodev", "usbcore" and, depending on
the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd".

"usbcore" and, depending on the USB host controller you have, "ehci-hcd",
"uhci-hcd" or "ohci-hcd".
Loading can be done as shown below:
[root@localhost home]# modprobe sn9c102
At this point the devices should be recognized. You can invoke "dmesg" to
analyze kernel messages and verify that the loading process has gone well:
Note that the module is called "sn9c102" for historic reasons, althought it
does not just support the SN9C102.
At this point all the devices supported by the driver and connected to the USB
ports should be recognized. You can invoke "dmesg" to analyze kernel messages
and verify that the loading process has gone well:

OVERVIEW.
This is a small interface that allows you to add support for any CCD/CMOS
image sensors connected to the SN9C10X bridges. The entire API is documented
image sensors connected to the SN9C1XX bridges. The entire API is documented
below. In the most general case, to support a sensor there are three steps
you have to follow:
1) define the main "sn9c102_sensor" structure by setting the basic fields;
2) write a probing function to be called by the core module when the USB
camera is recognized, then add both the USB ids and the name of that
function to the two corresponding tables SENSOR_TABLE and ID_TABLE (see
below);
function to the two corresponding tables in sn9c102_devtable.h;
3) implement the methods that you want/need (and fill the rest of the main
structure accordingly).
"sn9c102_pas106b.c" is an example of all this stuff. Remember that you do
