* [media] move the dvb/frontends to drivers/media/dvb-frontendsMauro Carvalho Chehab2012-08-131-626/+0
| | | | | | | Raise the DVB frontends one level up, as the intention is to remove the drivers/media/dvb directory. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] STV0288 increase delay between carrier searchMalcolm Priestley2012-03-191-1/+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.

* [media] dvb: Remove ops->info.type from frontendsMauro Carvalho Chehab2012-01-041-8/+0
| | | | | | | | | Now that this field is deprecated, and core generates it for DVBv3 calls, remove it from the drivers. It also adds .delsys on the few drivers where this were missed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] stv0288: convert set_fontend to use DVBv5 parametersMauro Carvalho Chehab2011-12-311-6/+3
| | | | | | | | | | | Instead of using dvb_frontend_parameters struct, that were designed for a subset of the supported standards, use the DVBv5 cache information. Also, fill the supported delivery systems at dvb_frontend_ops struct. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] Rename set_frontend fops to set_frontend_legacyMauro Carvalho Chehab2011-12-311-1/+1
| | | | | | | | | | | | | Passing DVBv3 parameters to set_frontend is not fun, as the core doesn't have any way to know if the driver is using the v3 or v5 parameters. So, rename the callback and add a new one to allow distinguish between a mixed v3/v5 paramenter call from a pure v5 call. After having all frontends to use the new way, the legacy call can be removed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] tuners: remove dvb_frontend_parameters from set_params()Mauro Carvalho Chehab2011-12-311-1/+1
| | | | | | | | | | | This is a big patch, yet trivial: now that all tuners use the DVBv5 way to pass parameters (e. g. via fe->dtv_property_cache), the extra parameter can be removed from set_params() call. After this change, very few DVBv3 specific stuff are left at the tuners. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] STV0288 frontend provide wider carrier search and DVB-S2 drop out. ↵tvboxspy2011-09-211-8/+21
| | | | | | | | | | | | | | | | | | | | | | resend The following patch provides wider carrier search. As with existing code search starts at MSB aligned. The boundary is widened to start at -9. In order to save time, if no carrier is detected at the start it advances to the next alignment until carrier is found. The stv0288 will detect a DVB-S2 carrier on all steps , a time out of 11 steps is introduced to drop out of the loop. In stv0288_set_symbol carrier and timing loops are restored to default values (inittab) before setting the symbol rate on each tune. A slight drift was noticed with full scan in the higher IF frequencies of each band. Signed-off-by: Malcolm Priestley <tvboxspy@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] STV0288 Register 42 - Incorrect settingsMalcolm Priestley2011-05-201-1/+1
| | | | | | | | | | | | Register 42 bits 2,3,6 and 7 should be set to 0. This gives difficult locking on some channels and may be compensated for by other methods. This affects any driver using the stv0288 frontend on the default or earda inittab. Signed-off-by: Malcolm Priestley <tvboxspy@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] DiSEqC bug fixed for stv0288 based interfacesMalcolm Priestley2010-10-211-9/+12
| | | | | | | | | | | | | | | | Fixed problem with DiSEqC communication. The message was wrongly modulated, so the DiSEqC switch was not work. This patch fixes DiSEqC messages, simple tone burst and tone on/off. I verified it with osciloscope against the DiSEqC documentation.

* V4L/DVB (12440): Use kzalloc for frontend states to have struct dvb_frontend ↵Matthias Schwarzott2009-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | properly This patch changes most frontend drivers to allocate their state structure via kzalloc and not kmalloc. This is done to properly initialize the embedded "struct dvb_frontend frontend" field, that they all have. The visible effect of this struct being uninitalized is, that the member "id" that is used to set the name of kernel thread is totally random. Some board drivers (for example cx88-dvb) set this "id" via videobuf_dvb_alloc_frontend but most do not. So I at least get random id values for saa7134, flexcop and ttpci based cards. It looks like this in dmesg: DVB: registering adapter 1 frontend -10551321 (ST STV0299 DVB-S) The related kernel thread then also gets a strange name like "kdvb-ad-1-fe--1".
