2012-04-09[media] af9035: fix and enhance I2C adapterAntti Palosaari1-8/+26
There was a bug I2C adapter writes and reads one byte too much. As the most I2C clients has auto-increment register addressing this leads next register from the target register overwritten by garbage data. As a change remove whole register address byte usage and write data directly to the I2C bus without saying what are register address bytes to firmware.

2012-03-19[media] stb0899: fix the limits for signal strength valuesKlaus Schmidinger1-3/+5
stb0899: fix the limits for signal strength values stb0899_read_signal_strength() adds an offset to the result of the table lookup. That offset must correspond to the lowest value in the lookup table, to make sure the result doesn't get below 0, which would mean a "very high" value since the parameter is unsigned. 'strength' and 'snr' need to be initialized to 0 to make sure they have a defined result in case there is no "internal->lock".

Remove incorrect SEC_MINI_B settings-TODO complete this section. Correct break and remove return -EINVAL within set tone. It appears there is a bug that occasionally something other than ON/OFF is sent stalling the driver. Just continue and write back registers. Set register b2 in setup.

2012-03-19[media] af9015: fix i2c failures for dual-tuner devices - part 2Antti Palosaari2-30/+48
Some changes for previous patch I liked to do. Just move tuner init and sleep to own functions from the demod init and sleep functions. Functionality remains still almost the same. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-03-19[media] af9015: fix i2c failures for dual-tuner devicesGordon Hecker2-0/+33
The i2c failures were caused by enabling both i2c gates at the same time while putting the tuners asleep. This patch removes the init() and sleep() callbacks from the tuner, to prevent frontend.c from calling i2c_gate_ctrl tuner init / sleep i2c_gate_ctrl without holding the lock. tuner init() and sleep() are instead called in frontend init() and sleep().

2012-03-19[media] dib0700: Drop useless check when remote key is pressedJean Delvare1-3/+0
struct dvb_usb_device *d can never be NULL so don't waste time checking for this. Rationale: the urb's context is set when usb_fill_bulk_urb() is called in dib0700_rc_setup(), and never changes after that. d is dereferenced unconditionally in dib0700_rc_setup() so it can't be NULL or the driver would crash right away.

2012-03-19[media] au8522: bug-fix: enable modulation AFTER tune (instead of before tuning)Michael Krufky1-5/+5
The au8522 driver programs the tuner after programming the demodulator, but the tuner should be programmed first. This patch fixes this behavior. EDIT: Apparantly Devin created a similar patch some time ago, but hasn't submitted it for merge. I never saw his patch, but I thank him anyhow for his efforts.

2012-03-19[media] dvb: earth-pt1: stop polling data when no one accesses the deviceAkihiro Tsukada1-23/+50
The driver started a kthread to poll the DMA buffers soon after probing, which relsuleted in 1000/sec sleeps and wakeups of the thread doing nothing useful until someone started feeding.

Support for m88rs2000 chip used in lmedm04 driver. Note there are still lock problems. Slow channel change due to the large block of registers sent in set_frontend. Version 2 differences. Front end is completely shut down when in sleep mode. This allow user to regain control of device. Kaffeine scan problem solved by removing register calls from get_frontend. Kaffeine seems to call get_frontend when updating signal data. This can happen in the middle of a tune stalling the driver. Change calculations to those in the DS3000 driver.

2012-03-19[media] STV0288 increase delay between carrier searchMalcolm Priestley1-1/+1
The current delay of 30uS is too short to recover any carrier. In the lmedm04 driver delays were added to overcome carrier lock problems. The typical delay was 30mS (2 x 15ms register write 0x2c and read 0x24). Other drivers that use STV0288 don't appear to have any delay are likely to have also suffered this problem.
