[media] use IS_ENABLED() macro

2013-02-06T11:24:09+00:00

This patch introduces the use of IS_ENABLED() macro. For example,
replacing:
 #if defined(CONFIG_I2C) || (defined(CONFIG_I2C_MODULE) && defined(MODULE))
with:
 #if IS_ENABLED(CONFIG_I2C)
All changes made by this patch respect the same replacement pattern.

[media] stv090x: On STV0903 do not set registers of the second path

2013-01-24T20:31:00+00:00

Sometimes there is a problem when trying to access the non-existing registers
of the second demodulator path on the STV0903.

This change removes the calls in case the driver is used on a STV0903.

[media] mb86a20s: remove global BER/PER counters if per-layer counters vanish

2013-01-24T16:28:32+00:00

If, for any reason, all per-layers counters stop, remove the
corresponding global counter.

[media] mb86a20s: fix the PER reset logic

2013-01-24T16:27:16+00:00

The logic that resets the device is wrong. It should be resetting
just the layer that got read. Also, stop is needed before updating
the counters.

[media] mb86a20s: some fixes at preBER logic

2013-01-24T16:26:55+00:00

The logic that resets the device is wrong. It should be resetting
just the layer that got read. Also, stop is needed before updating
the counters.
While there, rename it, as we'll soon introduce a postBER logic
there.

[media] mb86a20s: add block count measures (PER/UCB)

2013-01-24T16:24:59+00:00

Add both per-layer and global block error count and block count,
for PER and UCB measurements.

[media] mb86a20s: add CNR measurement

2013-01-23T21:10:49+00:00

Add Signal/Noise ratio measurement. On this device, a global measure
is taken by the demod. It also provides per-layer CNR measurements,
based on Modulation Error measures (MER).

[media] mb86a20s: improve bit error count for BER

2013-01-23T21:10:42+00:00

Do a better job on setting the bit error counters, in order to
have all layer measures to happen in a little less than one
second.
