V4L/DVB: ir-core: Distinguish sysfs attributes for in-hardware and raw decoders
Some devices have in-hardware Remote Controller decoder, while others need a software decoder to get the IR code. As each software decoder can be enabled/disabled individually, allowing multiple protocol decoding capability. On the other hand, hardware decoders have a limited protocol support, often being able of decoding just one protocol each time. So, each type needs a different set of capabilities to control the supported protocol(s). Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
