4. Overview and features
========================
-This driver supports the video interface of the devices mounting the ZC0301 or
-ZC0301P Image Processors and Control Chips.
+This driver supports the video interface of the devices mounting the ZC0301
+Image Processor and Control Chip.
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 ZC0301[P] driver can be found at the following URL:

CONFIG_USB_ZC0301=m
Type: short array (min = 0, max = 64)
Syntax: <-1|n[,...]>
Description: Specify V4L2 minor mode number:
- -1 = use next available
- n = use minor number n
- You can specify up to 64 cameras this way.
- For example:
- video_nr=-1,2,-1 would assign minor number 2 to the second
- registered camera and use auto for the first one and for every
- other camera.

Default: -1

Name: force_munmap
Type: bool array (min = 0, max = 64)
Syntax: <0|1[,...]>
Description: Force the application to unmap previously mapped buffer memory
- before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not
- all the applications support this feature. This parameter is
- specific for each detected camera.
- 0 = do not force memory unmapping
- 1 = force memory unmapping (save memory)

Name: frame_timeout
Type: uint array (min = 0, max = 64)
Syntax: <n[,...]>
Description: Timeout for a video frame in seconds. This parameter is
- specific for each detected camera. This parameter can be
- changed at runtime thanks to the /sys filesystem interface.

Name: debug
Type: ushort
Syntax: <n>
Description: Debugging information level, from 0 to 3:
- 0 = none (use carefully)
- 1 = critical errors
- 2 = significant informations
- 3 = more verbose messages
- Level 3 is useful for testing only, when only one device
- is used at the same time. It also shows some more informations
- about the hardware being detected. This module parameter can be
- changed at runtime thanks to the /sys filesystem interface.
