V4L/DVB (3116): tda9887 improvements: better defaults, better configurability.
- Set the tuner takeover point to 0x10 for NTSC/radio and 0x14 for PAL/SECAM. - Allow override through TDA9887_SET_CONFIG - PAL-N belongs with PAL-BG as does PAL-H. PAL-Nc belongs to PAL-M - Add SECAM-BGH - Set video freq to cVideoIF_38_90 for DK standards. - Add cTunerGainLow to radio, change deemphasis to 75 for mono. - Add ntsc module param for 'M' and 'J' (Japanese) standards. - Fix module handling for 2.4. - Now able to select all standards through pal/secam/ntsc module options Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@brturbo.com.br>
