---help---
This is a video4linux driver for the 'Multimedia eXtension Board'
TV card by Siemens-Nixdorf.
This driver is available as a module called mxb ( = code
which can be inserted in and removed from the running kernel
whenever you want). If you want to compile it as a module, say M
here and read <file:Documentation/modules.txt>.
config VIDEO_DPC
tristate "Philips-Semiconductors 'dpc7146 demonstration board'"
depends on VIDEO_DEV && PCI && I2C
---help---
This is a video4linux driver for the 'dpc7146 demonstration
board' by Philips-Semiconductors. It's the reference design
for SAA7146 bases boards, so if you have some unsupported
saa7146 based, analog video card, chances are good that it
will work with this skeleton driver.
This driver is available as a module called dpc7146 ( = code
which can be inserted in and removed from the running kernel
whenever you want). If you want to compile it as a module, say M
here and read <file:Documentation/modules.txt>.
