2010-12-29[media] stb0899: fix diseqc messages getting lostManu Abraham1-1/+1
- Some badly written applications in conjuction with certain SEC devices do send too many messages causing the DiSEqC bus to get congested. As a result, the end devices do get confused and hence do not respond. The issue was found by Julian Scheel.

2010-12-29[media] stb6100: Improve tuner performanceManu Abraham1-66/+127
- Reduce the amount of white noise present, which causes the demodulator a significant time to acquire a frontend lock on a whole. Frontend shows a large significant improvement in performance. Thanks to Peter Nayler for helping to identify the potential hotspots and fixing them. Signed-off-by: Manu Abraham <manu@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-12-29[media] IX2505V: i2c transfer error code ignoredMatthias Schwarzott1-1/+1
It seems that ix2505v driver ignores a i2c error in ix2505v_read_status_reg. This looks like a typing error using (ret = 1) instead of correct (ret == 1).

2010-12-29[media] au8522: cleanup code which disables audio decoderDevin Heitmueller1-15/+1
Cleanup the routine which disables the audio decoder. In particular, the i2s output was being shut off but the audio processor itself was not, resulting in more power being consumed than needed.

2010-12-29[media] au8522: Properly set default brightnessDevin Heitmueller1-1/+1
The chip's default value for the brightness didn't match what we were sending back in the queryctrl ioctl(), so if the application actually set the brightness to the "default", it would actually end up being way too bright.

By comparing the traffic between Pixelview (cx23102-based and Kworld (saa7134-based), the only difference is at register 0xd5. After some tests, It seems that it is used to change mode between serial and parallel. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-12-29[media] add a driver for mb86a20sMauro Carvalho Chehab4-0/+644
This adds the trivial bits to mb86a20s. As the driver won't touch at the channel/layer parameters, this may not be enough for receiving all channels, especially ISDB-Tsb, but the driver worked properly for receiving video channels on my tests.

2010-12-29[media] Re-write the s921 frontendMauro Carvalho Chehab8-573/+596
On our tests with Leadership ISDBT, the s921 frontend were not work. As its design contained some weird things, it ended to be easier to just re-write it, getting another frontend as an example (cx24123). As the old s921 driver weren't used, there's no regression. Some info from the old frontend were used as a way to double check the behavior that were noticed on the USB dumps retrieved from Leadership driver.
