2012-08-13[media] move the dvb/frontends to drivers/media/dvb-frontendsMauro Carvalho Chehab
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>

2012-01-06[media] af9013: change & to &&Dan Carpenter
This is just a cleanup, it doesn't change how the code works. These are compound conditions and not bitwise operations so it should be && and not &. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-01-06[media] af9013: Fix typo in get_frontend() functionGianluca Gennari
This patch fixes an obvious typo in the get_frontend() function of the af9013 driver, recently rewritten by Antti Palosaari. Signed-off-by: Gianluca Gennari <gennarone@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-01-04[media] dvb: Remove ops->info.type from frontendsMauro Carvalho Chehab
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>
2011-12-31[media] dvb: don't require a parameter for get_frontendMauro Carvalho Chehab
Just like set_frontend, use the dvb cache properties for get_frontend. This is more consistent, as both functions are now symetric. Also, at the places get_frontend is called, it makes sense to update the cache. Most of this patch were generated by this small perl script: while (<>) { $file .= $_; } if ($file =~ m/\.get_frontend\s*=\s*([\d\w_]+)/) { my $get = $1; $file =~ s/($get)(\s*\([^\,\)]+)\,\s*struct\s+dtv_frontend_properties\s*\*\s*([_\d\w]+)\)\s*\{/\1\2)\n{\n\tstruct dtv_frontend_properties *\3 = &fe->dtv_property_cache;/g; } print $file; Of course, the changes at dvb_frontend.[ch] were made by hand, as well as the changes on a few other places, where get_frontend() is called internally inside the driver. On some places, get_frontend() were just a void function. Those occurrences were removed, as the DVB core handles such cases. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-12-31[media] af9013: convert get|set_fontend to use DVBv5 parametersMauro Carvalho Chehab
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>
2011-12-31[media] dvb-core: add support for a DVBv5 get_frontend() callbackMauro Carvalho Chehab
Creates a DVBv5 get_frontend call, renaming the DVBv3 one to get_frontend_legacy(), while not all frontends are converted. After the conversion for all drivers, get_frontend_legacy() will be removed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-12-31[media] Rename set_frontend fops to set_frontend_legacyMauro Carvalho Chehab
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>
2011-12-31[media] tuners: remove dvb_frontend_parameters from set_params()Mauro Carvalho Chehab
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>
2011-12-30[media] af9013: rewrite whole driverAntti Palosaari
Rewrite whole af9013 demod driver in order to decrease I2C I/O. We need to decrease I2C load since AF9015 (I2C adapter / USB-bridge used) seems to have some problems under heavy I2C traffic. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-11-24[media] af9013: use .get_if_frequency() when possibleAntti Palosaari
Get IF frequency from tuner if tuner provides it. Remove TDA18271 and TDA18218 IF frequency hacks since both tuners provides .get_if_frequency(). Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-03-22[media] af9013: reimplement firmware downloadAntti Palosaari
Split FW download packages smarter way and bug free. Implementation is based of Andrea Merello's example he provided for tda18218 driver. Count remaining FW bytes down in loop instead of division and modulo combination used earlier.

2011-01-19[media] af9013: fix AF9013 TDA18271 IF configAntti Palosaari
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.
