[media] dvb: Remove ops->info.type from frontends

2012-01-04T19:30:34+00:00

Now that this field is deprecated, and core generates it for
DVBv3 calls, remove it from the drivers.

It also adds .delsys on the few drivers where this were missed.

[media] dvb: don't require a parameter for get_frontend

2011-12-31T12:28:23+00:00

Just like set_frontend, use the dvb cache properties for get_frontend.
This is more consistent, as both functions are now symetric. Also,
at the places get_frontend is called, it makes sense to update the
cache.

Most of this patch were generated by this small perl script:

	while (<>) { $file .= $_; }
	if ($file =~ m/\.get_frontend\s*=\s*([\d\w_]+)/) {
		my $get = $1;
		$file =~ s/($get)(\s*\([^\,\)]+)\,\s*struct\s+dtv_frontend_properties\s*\*\s*([_\d\w]+)\)\s*\{/\1\2)\n{\n\tstruct dtv_frontend_properties *\3 = &fe->dtv_property_cache;/g;
	}
	print $file;

Of course, the changes at dvb_frontend.[ch] were made by hand,
as well as the changes on a few other places, where get_frontend()
is called internally inside the driver.

On some places, get_frontend() were just a void function. Those
occurrences were removed, as the DVB core handles such cases.

[media] dib8000: Remove the old DVBv3 struct from it and add delsys

2011-12-31T11:16:43+00:00

This driver only uses the DVBv5 struct. All it needs is to remove
the non-used params var, and to add the ISDB-T to the delivery
systems.

[media] dvb-core: add support for a DVBv5 get_frontend() callback

2011-12-31T11:10:49+00:00

Creates a DVBv5 get_frontend call, renaming the DVBv3 one to
get_frontend_legacy(), while not all frontends are converted.

After the conversion for all drivers, get_frontend_legacy()
will be removed.

[media] Rename set_frontend fops to set_frontend_legacy

2011-12-31T11:09:43+00:00

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.

After having all frontends to use the new way, the legacy
call can be removed.

[media] tuners: remove dvb_frontend_parameters from set_params()

2011-12-31T10:57:29+00:00

This is a big patch, yet trivial: now that all tuners use the DVBv5
way to pass parameters (e. g. via fe->dtv_property_cache), the
extra parameter can be removed from set_params() call.

After this change, very few DVBv3 specific stuff are left at the
tuners.

[media] DiBcom: protect the I2C bufer access

2011-08-06T12:25:15+00:00

This patch protects the I2C buffer access in order to manage concurrent
access. This protection is done using mutex.
Furthermore, for the dib9000, if a pid filtering command is
received during the tuning, this pid filtering command is delayed to
avoid any concurrent access issue.
