2011-01-19[media] af9013: fix AF9013 TDA18271 IF configAntti Palosaari1-2/+2
IF freq for DVB-T 7 MHz and 8 MHz was set slightly wrong. Due to that it didn't worked at all (?) for 7 MHz channels and most likely performance was dropped for 8 MHz channels. That bug was pointed by few people during last two months. Thank you. Trivial fix. Compile tested only due to lack of proper HW and signal.

2010-10-21[media] af9013: cache some reg values to reduce reg readsAntti Palosaari1-23/+32
Demod + tuner specific RF AGC and IF AGC limit values are read from demod memory in every signal strength query. Cache those to reduce I2C traffic. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2010-08-02V4L/DVB: af9013: fix commentsAntti Palosaari1-1/+1
Fix comments. It is demodulator driver not DVB USB -bridge. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2010-08-02V4L/DVB: af9013: af9013_read_status() refactoringAntti Palosaari1-16/+20
Function af9013_read_status() refactoring. Read lock bits in different order to save count of register reads. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-08-02V4L/DVB: af9013: program tuner before demodulatorAntti Palosaari1-4/+4
Program tuner before demodulator in case of channel set. Earlier it was programmed during demodulator programming. This seems to resolve weird error where demodulator misses sometimes ability to gain lock. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-07-24V4L/DVB (12269): af9013: auto-detect parameters in case of garbage given by appAntti Palosaari1-7/+18
Request demodulator auto-detect transmission parameters in case of garbage parameters provided by application for compatibility. That's needed at least for MPlayer compatibility currently. Thanks to Jelle de Jong for reporting issue and providing SSH access to Devin for debugging. Thanks to Devin Heitmueller for hard debug work he did to find that bug.

2009-06-17V4L/DVB (11723): Link firmware to physical deviceJean Delvare1-1/+1
Use the physical device rather than the i2c adapter as the reference device when loading firmwares. This will prevent the sysfs name collision with i2c-dev that has been reported many times. I may have missed other drivers which need the same fix. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
