2012-08-09[media] au0828: prevent i2c gate from being kept open while in analog modeDevin Heitmueller4-5/+16
The original implementation of the analog support would use an i2c_gate_ctrl function when using the digital side of the au8522, but on the analog side we would always just force the gate open and leave it open all the time. This can have adverse effects on the xc5000 given the tuner is receiving all the spurious i2c traffic (a problem which can be exaggerated due to bugs in the au0828 i2c hardware implementation). Rework the existing hack to only open/close the gate when actually talking to the tuner. This logic might need to be reworked a bit if anybody ever tries to add support for a board that has the au0828/au8522 but doesn't have digital support implemented (because the i2c_gate_ctrl callback is being set in the DVB attach). However given how few different models are in circulation, this can be deferred until such a situation arises (if ever).

2012-08-09[media] au8522: fix regression in logging introduced by separation of modulesDevin Heitmueller1-2/+7
The au8522 driver was broken into three modules (dig, decoder, common), and as a result the debug modprobe option doesn't work for any of the common functions. Copy the module macros over to the common module so that the debug option works again. Signed-off-by: Devin Heitmueller <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2012-08-09[media] au8522: Fix off-by-one in SNR table for QAM256Devin Heitmueller1-48/+48
The table of valid SNR values for QAM 256 is off by one, and as a result if the SNR is oscillating between 40.0 and 39.9 dB, tools like azap show it going back and forth between 40.0 and 0 (misleading some people, including myself, to think signal lock is being lost or there is a problem with register reads). Fix the table so that 40.0 dB is properly represented.

2012-08-09[media] au8522: fix intermittent lockup of analog video decoderDevin Heitmueller2-5/+29
It turns up the autodetection for the video standard in the au8522 is prone to hanging the chip until a reset is performed. This condition is trivial to reproduce simply by tuning to a station and then rapidly unplugging/ replugging the coax feed. Because we've never claimed to support anything other than NTSC-M, just disable the video-standard autodetection logic and force it to always be NTSC-M.

2012-07-30[media] rtl2832.c: minor cleanupHans-Frieder Vogt1-1/+1
The current formulation of the bw_params loop uses the counter j as an index for the first dimension of the bw_params array which is later incremented by the variable i. It is evaluated correctly only, because j is initialized to 0 at the beginning of the loop. I think that explicitly using the index 0 better reflects the intent of the expression.

2012-07-06[media] drxk: Make the QAM demodulator command parameters configurableMartin Blumenstingl3-26/+98
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.

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.

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.

2012-06-18[media] DVB: stb0899: speed up getting BER valuesKlaus Schmidinger1-16/+6
stb0899_read_ber() takes 500ms (half a second!) to deliver the current BER value. Apparently it takes 5 subsequent readings, with a 100ms pause between them (and even before the first one). This is a real performance brake if an application freqeuently reads the BER of several devices. The attached patch reduces this to a single reading, with no more pausing. I didn't observe any negative side effects of this change.
