media: dvb: i2c transfers over usb cannot be done from stack

2017-10-27T08:39:12Z

commit b4756707152700c96acdfe149cb1ca4cec306c7a upstream. Since commit 29d2fef8be11 ("usb: catch attempts to submit urbs with a vmalloc'd transfer buffer"), the AverMedia AverTV DVB-T USB 2.0 (a800) fails to probe.

media: dvb-frontends/stv0367: Improve DVB-C/T frontend status

2017-06-25T13:48:45Z

The stv0367 driver provide a lot of status on its state machine. Change the logic to provide more information about frontend locking status. Also, while any detailed status isn't available, provide a more complete FE_STATUS for DVB-T. Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Daniel Scheller

media: dvb-frontends/stv0367: DVB-C signal strength statistics

2017-06-25T12:10:44Z

Provide QAM/DVB-C signal strength in decibel scale. Values returned from stv0367cab_get_rf_lvl() are good but need to be multiplied as they're in 1dBm precision. Signed-off-by: Daniel Scheller Signed-off-by: Mauro Carvalho Chehab

media: dvb-frontends/stv0367: update UCB readout condition logic

2017-06-25T12:10:06Z

Since the other statistics are read when fe_status conditions are TRUE, change the ucblocks readout logic to match this aswell. Signed-off-by: Daniel Scheller Signed-off-by: Mauro Carvalho Chehab

media: stv0367: prevent division by zero

2017-06-25T12:07:45Z

While there's a test at the SNR calculus to avoid division by zero, it will still follow the path that would do the division. So, add a missing break there. Signed-off-by: Mauro Carvalho Chehab

media: dvb-frontends/stv0367: SNR DVBv5 statistics for DVB-C and T

2017-06-25T12:06:32Z

Add signal-to-noise-ratio as provided by the demodulator in decibel scale. QAM/DVB-C needs some intlog calculation to have usable dB values, OFDM/ DVB-T values from the demod look alright already and are provided as-is. Signed-off-by: Daniel Scheller Signed-off-by: Mauro Carvalho Chehab

media: dvb-frontends/cxd2841er: require STATE_ACTIVE_* for agc readout

2017-06-25T12:05:26Z

When the demod driver puts the demod into sleep or shutdown state and it's status is then polled e.g. via "dvb-fe-tool -m", i2c errors are printed to the kernel log. If the last delsys was DVB-T/T2: cxd2841er: i2c wr failed=-5 addr=6c reg=00 len=1 cxd2841er: i2c rd failed=-5 addr=6c reg=26 and if it was DVB-C: cxd2841er: i2c wr failed=-5 addr=6c reg=00 len=1 cxd2841er: i2c rd failed=-5 addr=6c reg=49 This happens when read_status unconditionally calls into the read_signal_strength() function which triggers the read_agc_gain_*() functions, where these registered are polled. This isn't a critical thing since when the demod is active again, no more such errors are logged, however this might make users suspecting defects. Fix this by requiring STATE_ACTIVE_* in priv->state. If it isn't in any active state, additionally set the strength scale to NOT_AVAILABLE.

media: dvb-frontends/stv0367: split SNR determination into functions

2017-06-24T20:42:47Z

The read_snr() functions currently do some magic to return relative scale values when called. Split out register readouts into separate functions so the functionality can be reused in some other way. Signed-off-by: Daniel Scheller Signed-off-by: Mauro Carvalho Chehab

media: dvb-frontends/stv0367: initial DDB DVBv5 stats, implement ucblocks

2017-06-24T20:42:18Z

This adds the basics to stv0367ddb_read_status() to be able to properly provide signal statistics in DVBv5 format. Also adds UCB readout and provides those values. Also, don't return -EINVAL in ddb_read_status() if active_demod_state indicates no delivery system. Signed-off-by: Daniel Scheller Signed-off-by: Mauro Carvalho Chehab

media: dvb-frontends/lnbh25: improve kernellog output

2017-06-24T20:05:19Z

Use dev_dbg() in conjunction with the %*ph format macro to print the vmon status debug, thus hiding continuous hexdumping from default log levels. Also, change the attach success log line from error to info severity. Signed-off-by: Daniel Scheller Acked-by: Abylay Ospan Signed-off-by: Mauro Carvalho Chehab
