V4L/DVB (3916): AverMedia 6 Eyes AVS6EYES support
Add support for the AverMedia 6 Eyes MJPEG card.
- Updated drivers/media/video/Kconfig with AVS6EYES
options.
- Added CONFIG_VIDEO_ZORAN_AVS6EYES to
drivers/media/video/Makefile.
- Added I2C_DRIVERID_BT866 and I2C_DRIVERID_KS0127 to
include/linux/i2c-id.h
- Added drivers/media/video/ks0127.c, imported and modified from
the Marvel project.
- Added drivers/media/video/ks0127.h, imported and modified from
the Marvel project.
- Added drivers/media/video/bt866.c, ported from a 2.4 version
by Christer Weinigel.
- Added AVS6EYES to drivers/media/video/zoran_card.c
- Added input_mux to all cards in drivers/media/video/zoran_card.c
- Added input mux module parameter to drivers/media/video/zoran_card.c
- Added AVS6EYES to card_type in drivers/media/video/zoran.h
- Added input_mux to card_info in drivers/media/video/zoran.h
- Upped BUZ_MAX_INPUT in drivers/media/video/zoran.h from 8 to 16,
as the AVS6EYES has 10.
- Updated Documentation/video4linux/Zoran with information about AVS6EYES.
