media: rc: rename RC_TYPE_* to RC_PROTO_* and RC_BIT_* to RC_PROTO_BIT_*

2017-08-20T14:02:48+00:00

RC_TYPE is confusing and it's just the protocol. So rename it.

media: rc-core: rename input_name to device_name

2017-08-20T13:43:52+00:00

When an ir-spi is registered, you get this message.

rc rc0: Unspecified device as /devices/platform/soc/3f215080.spi/spi_master/spi32766/spi32766.128/rc/rc0

"Unspecified device" refers to input_name, which makes no sense for IR
TX only devices. So, rename to device_name.

Also make driver_name const char* so that no casts are needed anywhere.

Now ir-spi reports:

rc rc0: IR SPI as /devices/platform/soc/3f215080.spi/spi_master/spi32766/spi32766.128/rc/rc0

[media] rc-main: assign driver type during allocation

2017-01-30T15:59:57+00:00

The driver type can be assigned immediately when an RC device
requests to the framework to allocate the device.

This is an 'enum rc_driver_type' data type and specifies whether
the device is a raw receiver or scancode receiver. The type will
be given as parameter to the rc_allocate_device device.

Change accordingly all the drivers calling rc_allocate_device()
so that the device type is specified during the rc device
allocation. Whenever the device type is not specified, it will be
set as RC_DRIVER_SCANCODE which was the default '0' value.

[media] rc: rc-loopback: Add loopback of filter scancodes

2017-01-30T15:56:21+00:00

Add the s_wakeup_filter callback to the rc-loopback driver, which instead
of setting the filter just feeds the scancode back through the input
device so that it can be verified.

[media] rc: raw IR drivers cannot handle cec, unknown or other

2017-01-30T14:40:50+00:00

unknown and other are for IR protocols for which we have no decoder,
so the raw IR drivers have no chance of generating them. cec is not
an IR protocol.

[media] media: Drop FSF's postal address from the source code files

2017-01-27T13:38:09+00:00

Drop the FSF's postal address from the source code files that typically
contain mostly the license text. Of the 628 removed instances, 578 are
outdated.

The patch has been created with the following command without manual edits:

git grep -l "675 Mass Ave\|59 Temple Place\|51 Franklin St" -- \
	drivers/media/ include/media|while read i; do i=$i perl -e '
open(F,"< $ENV{i}");
$a=join("", );
$a =~ s/[ \t]*\*\n.*You should.*\n.*along with.*\n.*(\n.*USA.*$)?\n//m
	&& $a =~ s/(^.*)Or, (point your browser to) /$1To obtain the license, $2\n$1/m;
close(F);
open(F, "> $ENV{i}");
print F $a;
close(F);'; done

Revert "[media] rc: rc-loopback: Add loopback of filter scancodes"

2015-08-19T10:02:53+00:00

This reverts commit 2e4ebde269236da2a41183522127715b6d9d80ce.

The current code is not mature enough, the API should allow a single
protocol to be specified. Also, the current code contains heuristics
that will depend on module load order.

[media] rc-core: remove protocol arrays

2014-07-25T22:10:43+00:00

The basic API of rc-core used to be:

	dev = rc_allocate_device();
	dev->x = a;
	dev->y = b;
	dev->z = c;
	rc_register_device();

which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:

	dev = rc_allocate_device();
	dev->x = a;
	rc_set_allowed_protocols(dev, RC_BIT_X);
	dev->z = c;
	rc_register_device();

There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

[media] rc: abstract access to allowed/enabled protocols

2014-03-11T16:24:39+00:00

The allowed and enabled protocol masks need to be expanded to be per
filter type in order to support wakeup filter protocol selection. To
ease that process abstract access to the rc_dev::allowed_protos and
rc_dev::enabled_protocols members with inline functions.
