From f98c55ea18e87905bdf69eb4a187e94572ed9494 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 9 Jan 2006 15:25:18 -0200 Subject: 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 Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/tda9887.c | 164 +++++++++++++++++++++++++++++++++--------- 1 file changed, 132 insertions(+), 32 deletions(-) (limited to 'drivers') diff --git a/drivers/media/video/tda9887.c b/drivers/media/video/tda9887.c index ceaa29975c8..32f133ed0b0 100644 --- a/drivers/media/video/tda9887.c +++ b/drivers/media/video/tda9887.c @@ -114,6 +114,9 @@ static struct i2c_client client_template;
