config USB_PWC
tristate "USB Philips Cameras"
depends on VIDEO_DEV
select VIDEOBUF2_VMALLOC
help
Say Y or M here if you want to use one of these Philips & OEM
webcams:
* Philips PCA645, PCA646
* Philips PCVC675, PCVC680, PCVC690
* Philips PCVC720/40, PCVC730, PCVC740, PCVC750
* Philips SPC900NC
* Askey VC010
* Logitech QuickCam Pro 3000, 4000, 'Zoom', 'Notebook Pro'
and 'Orbit'/'Sphere'
* Samsung MPC-C10, MPC-C30
* Creative Webcam 5, Pro Ex
* SOTEC Afina Eye
* Visionite VCS-UC300, VCS-UM100
The PCA635, PCVC665 and PCVC720/20 are not supported by this driver
and never will be, but the 665 and 720/20 are supported by other
drivers.
Some newer logitech webcams are not handled by this driver but by the
Usb Video Class driver (linux-uvc).
The built-in microphone is enabled by selecting USB Audio support.
To compile this driver as a module, choose M here: the
module will be called pwc.
config USB_PWC_DEBUG
bool "USB Philips Cameras verbose debug"
depends on USB_PWC
help
Say Y here in order to have the pwc driver generate verbose debugging
messages.
A special module options 'trace' is used to control the verbosity.
config USB_PWC_INPUT_EVDEV
bool "USB Philips Cameras input events device support"
default y
depends on USB_PWC && (USB_PWC=INPUT || INPUT=y)
help
This option makes USB Philips cameras register the snapshot button as
an input device to report button events.
If you are in doubt, say Y.

/* This tables contains entries for the 730/740/750 (Kiara) camera, with
4 different qualities (no compression, low, medium, high).
It lists the bandwidth requirements for said mode by its alternate interface
number. An alternate of 0 means that the mode is unavailable.
There are 6 * 4 * 4 entries:
6 different resolutions subqcif, qsif, qcif, sif, cif, vga
6 framerates: 5, 10, 15, 20, 25, 30
4 compression modi: none, low, medium, high
When an uncompressed mode is not available, the next available compressed mode
will be chosen (unless the decompressor is absent). Sometimes there are only
1 or 2 compressed modes available; in that case entries are duplicated.
