[media] dib8000: improve the message that reports per-layer locks

2014-07-07T12:59:01+00:00

The message is currently highly encoded:
	[70299.863521] DiB8000: Mpeg locks [ L0 : 0 | L1 : 1 | L2 : 0 ]

And doesn't properly reflect that some problems might have happened.
Instead, display it as:
	[75160.822321] DiB8000: Not all ISDB-T layers locked in 32 ms: Layer A NOT LOCKED, Layer B locked, Layer C not enabled

In order to better reflect what's happening with layer locking.

[media] dib8000: improve debug messages

2014-07-07T12:59:00+00:00

When debug is enabled:
	- Report when frontend gets restarted;
	- Be coherent on the displayed lines;
	- Show the transmission mode;
	- Hide unused layers.

No functional changes (except at the printk's).

[media] dib8000: Update the ADC gain table

2014-07-07T12:58:59+00:00

This table doesn't match the new one.
Update it.

[media] dib8000: use jifies instead of current_kernel_time()

2014-07-07T12:58:59+00:00

Instead of doing the tuning delays and timeouts using
current_kernel_time(), use jiffies. That consumes less
CPU cycles, and it is monotonic.

[media] dib8000: Fix the sleep time at the state machine

2014-07-07T12:58:42+00:00

msleep() is not too precise: its precision depends on the
HZ config. As the driver selects precise timings for the
state machine, change it to usleep_range().

[media] dib8000: Restart sad during dib8000_reset

2014-07-07T12:56:30+00:00

Just like the Windows driver, restart SAD during reset

[media] dib8000: In auto-search, try first with partial reception enabled

2014-07-07T12:56:23+00:00

TV broadcasters generally use partial reception. So, enable it by
default in auto-search mode. The driver will latter detect if the
transmission is on some other mode.

[media] dib8000: remove a double call for dib8000_get_symbol_duration()

2014-07-07T12:56:13+00:00

The symbol duration was already obtained at CT_DEMOD_START.
No need to do it again at CT_DEMOD_STEP_3.

[media] dib8000: Fix: add missing 4K FFT mode

2014-07-07T12:55:38+00:00

Without that, tuning may fail on 4K FFT mode, as the transmission
parameter cache will be initialized with a wrong value.

[media] dib8000: Fix alignments at dib8000_tune()

2014-07-07T12:55:31+00:00

There are two tabs instead of one aligning this struct.
Worse than that, on some places, the alignment is wrong.
Fix it.

No functional changes.
