[media] ngene: CXD2099AR Common Interface driver
Driver for the Common Interface Controller CXD2099AR. Supports the CI of the cineS2 DVB-S2. For now, data is passed through '/dev/dvb/adapterX/sec0': - Encrypted data must be written to 'sec0'. - Decrypted data can be read from 'sec0'. - Setup the CAM using device 'ca0'. Signed-off-by: Ralph Metzler <rjkm@metzlerbros.de> Signed-off-by: Oliver Endriss <o.endriss@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
