This adds radio receiver and transmitter support. Part of that is common to both and so is placed in the radio-common source. These drivers also support RDS. In order to generate valid RDS data a simple RDS generator is implemented in rds-gen. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
