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>
2012-07-06[media] drxk: Improve loggingMartin Blumenstingl
This patch simply fixes some logging calls: - Use KERN_INFO when printing the chip status. - Add a missing space when logging the drxk_gate_ctrl call. - Use the same logging text as always if the scu_command in GetQAMLockStatus fails.

2012-07-06[media] drxk: Make the QAM demodulator command parameters configurableMartin Blumenstingl
Currently there are two different implementations (in the firmware) for the QAM demodulator command: one takes 4 and the other takes 2 parameters. The driver shows an error in dmesg When using the 4-parameter command with firmware that implements the 2-parameter command. Unfortunately this happens every time when chaning the frequency (on DVB-C). This patch simply makes configurable, how many command parameters will be used. All existing drxk_config instances using the "drxk_a3.mc" were updated because this firmware is the only loadable firmware where the QAM demodulator command takes 4 parameters. Some firmwares in the ROM might also use it. The drxk instances in the em28xx-dvb driver were also updated to silence the warnings. If no qam_demod_parameter_count is given in the drxk_config struct, then the correct number of parameters will be auto-detected.

2012-06-29[media] drxk: prevent doing something wrong when init is not okMauro Carvalho Chehab
If firmware is not loaded for some reason, or if it is not ready yet, it makes no sense to honour to any DVB callbacks. So, return -EAGAIN, as the error condition may be temporary. If the device doesn't initialize, either because it requires a firmware or because there's an error during init_drxk, returns -ENODEV, to indicate such error, on all DVB callbacks.

2012-06-29[media] drxk: change it to use request_firmware_nowait()Mauro Carvalho Chehab
The firmware blob may not be available when the driver probes. Instead of blocking the whole kernel use request_firmware_nowait() and continue without firmware. This shouldn't be that bad on drx-k devices, as they all seem to have an internal firmware. So, only the firmware update will take a little longer to happen.

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>

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.

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.

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] 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.
