2012-04-18[media] drxk: Does not unlock mutex if sanity check failed in scu_command()Alexey Khoroshilov
If sanity check fails in scu_command(), goto error leads to unlock of an unheld mutex. The check should not fail in reality, but it nevertheless worth fixing.

2012-01-21[media] drxk: Don't assume a default firmware nameMauro Carvalho Chehab
Move the ngene/ddbridge firmware into their drivers. There are two reasons for that: 1) The firmware used there didn't work for a few devices I tested here (Terratec H5, H6 and H7); 2) At least Terratec H7 doesn't seem to require a firmware for it to work. After this change, if firmware is not specified, the driver will use a rom-based firmware (this seems to be the case for Terratec H7, although I need to better check the USB dumps to be sure about that). In any case, the firmware seems to be optional, as the DRX-K driver don't return the firmware load error. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-01-05[media] drxk: remove ops.info.frequency_stepsize from DVB-CMauro Carvalho Chehab
ops.info.frequency_stepsize is used only for DVB-T & friends. For DVB-C, the step size is calculated using the symbol rate. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-01-04[media] drxk: Add support for parallel mode and prints mpeg modeMauro Carvalho Chehab
While the driver has support for both serial and parallel mode, There's was way to select serial mode via configuration. Add a config option for that, while keeping the default in serial mode. Also, at debug mode, it will now print a message when mpeg is enabled/disabled, and showing if parallel or serial mode were selected, helping developers to double-check if the DRX-K is at the right mode.

2011-12-31[media] drxk: convert 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>

2011-12-20[media] Remove Annex A/C selection via roll-off factorMauro Carvalho Chehab

2011-12-09[media] drxk: Switch the delivery system on FE_SET_PROPERTYMauro Carvalho Chehab
The DRX-K doesn't change the delivery system at set_properties, but do it at frontend init. This causes problems on programs like w_scan that, by default, opens both frontends. Instead, explicitly set the format when set_parameters callback is called. Tested-by: Eddi De Pieri <eddi@depieri.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-11-11[media] Properly implement ITU-T J.88 Annex C supportMauro Carvalho Chehab
The Annex C support were broken with the previous implementation, as, at xc5000 and tda18271c2dd, it were choosing the wrong bandwidth for some symbol rates. At DRX-J, it were always selecting Annex A, even having Annex C support coded there. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-09-03[media] dvb-core, tda18271c2dd: define get_if_frequency() callbackMauro Carvalho Chehab
Tuners in general convert a high frequency carrier into an Intermediate Frequency (IF). Digital tuners like tda18271, xc3028, etc. generally allow changing the IF frequency, although they generally have recommented settings for the IF. Analog tuners, have a fixed IF frequency, that depends on the physical characteristics of some analog components. For digital tuners, it makes sense to have ways to configure IF, via the tuner's configuration structure, like what's done inside the tda18271-fe maps. The demods need to know what IF is used by the tuner, as it will need to convert internally from IF into baseband. Currently, the bridge driver needs to fill a per-demod configuration struct for it, or pass it via a dvb_attach parameter. The tda18271 datasheet recommends to use different IF's for different delivery system types and for different bandwidths. The DRX-K demod also needs to know the IF frequency in order to work, just like all other demods. However, as it accepts different delivery systems (DVB-C and DVB-T), the IF may change if the standard and/or bandwidth is changed. So, the usual procedure of passing it via a config struct doesn't work. One might try to code it as two separate IF frequencies, or even as a table in function of the delivery system and the bandwidth, but this will be messy. So, it is better and simpler to just add a new callback for it and require the tuners that can be used with MFE frontends like drx-k to implement a new callback to return the used IF.

2011-07-27[media] drxk: Fix a bug at some switches that broke DVB-TMauro Carvalho Chehab
The error propagation changeset c23bf4402 broke the DVB-T code. The legacy way for propagate errors was: do { status = foo_func() if (status < 0) break; } while (0); return status; However, on a few places, it was doing: do { switch(foo) { case bar: status = foo_func() if (status < 0) break; break; } switch(foo2) { case bar: status = foo_func() if (status < 0) break; break; } ... } while (0); return (status) The inner error break were not working, as it were breaking only the switch, instead of the do. The solution used were to do a s/break/goto error/ at the inner breaks, but preserving the last break. Onfortunately, on a few switches, the replacement were applied also to the final break for the case statements. Fix the broken logic, by reverting them to break, where pertinent, in order to fix DVB-T support. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-07-27[media] Remove the double symbol increment hack from drxk_hardMauro Carvalho Chehab
Both ngene and ddbrige calls dvb_attach once for drxk_attach. The logic used there, and by tda18271c2dd driver is different from similar logic on other frontends. The right fix is to change them to use the same logic, but, while we don't do that, we need to patch em28xx-dvb in order to do cope with ngene/ddbridge magic. While here, document why drxk_t_release should do nothing. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-07-27[media] drxk: Add a fallback method for QAM parameter settingMauro Carvalho Chehab
The QAM standard is set using this scu_command: SCU_RAM_COMMAND_STANDARD_QAM | SCU_RAM_COMMAND_CMD_DEMOD_SET_PARAM The driver implements a version that has 4 parameters, however, Terratec H5 needs to break this into two separate commands, otherwise, DVB-C doesn't work. With this fix, scan is now properly working and getting the channel list: >>> tune to: 609000000:INVERSION_AUTO:5217000:FEC_3_4:QAM_256 >>> tuning status == 0x00 >>> tuning status == 0x07 >>> tuning status == 0x1f 0x0093 0x0026: pmt_pid 0x0758 (null) -- SporTV2 (running, scrambled) 0x0093 0x0027: pmt_pid 0x0748 (null) -- SporTV (running, scrambled) 0x0093 0x0036: pmt_pid 0x0768 (null) -- FX (running, scrambled) 0x0093 0x0052: pmt_pid 0x0788 (null) -- The History Channel (running, scrambled) Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-07-27[media] drxk: Improve the scu_command error messageMauro Carvalho Chehab

This happens with Terratec H5 firmware. It adds 2 new error conditions, and something useful to track what the heck is that. I suspect that the scu_command is dependent on the firmware revision.

2011-07-27[media] drxk: Improves the UIO handlingMauro Carvalho Chehab
The driver is too limited: it assumes that UIO is used only for controlling the antenna, and that only UIO-1 is in usage. However, from Terratec H7 driver [1], 3 UIO's can be used. In fact, it seems that H7 needs to use all 3. So, make the code generic enough to handle the most complex scenario. For now, only antena GPIO can be specified, but is is easier now to add the other GPIO/UIO needs. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-07-27[media] drxk: Proper handle/propagate the error codesMauro Carvalho Chehab
This driver is very big and complex. An error happening in the middle of any initialization may cause the frontend to not work. So, it needs to properly propagate error codes internally and to userspace. Also, printing the error codes at the places it happened helps to discover were's a bug at the code. Before this change, a do { } while (0) loop and lots of breaks inside were used to propagate errors. While this works, if there are loops inside other loops, it could be easy to forget to add another break, causing the error to not abort the function. Also, as not all functions were reporting errors, it is hard to discover why something failed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-07-27[media] drxk: Move I2C address into a config structureMauro Carvalho Chehab
Currently, the only parameter to be configured is the I2C address. However, Terratec H5 logs shows that it needs a different setting for some things, and it has its own firmware.

2011-07-27[media] drxk: remove _0 from read/write routinesMauro Carvalho Chehab
The normal 16-bits read routine is called as "Read16_0". This is due to a flags that could optionally be passed. Yet, on no places at the code, a flag is passed there. The same happens with 16-bits write and 32-read/write routines, and with WriteBlock. Also, using flags, is an exception: there's no place currently using flags, except for an #ifdef at WriteBlock. Rename the function as just "read16", and the one that requires flags, as "read16_flags". This helps to see where the flags are used, and also avoid using CamelCase on Kernel.
