media: dvb-frontends: MaxLinear MxL5xx DVB-S/S2 tuner-demodulator driver This adds the frontend driver for the MaxLinear MxL5xx family of tuner- demodulators, as used on Digital Devices MaxS4/8 four/eight-tuner cards. The driver was picked from the dddvb vendor driver package and - judging solely from the diff - has undergone a 100% rework: - Silly #define's used to pass multiple values to functions were expanded. This resulted in macro/register names not being usable anymore for such occurences, but makes the code WAY more read-, understand- and maintainable. - CamelCase was changed to kernel_case - All typedef were removed - Overall code style was fixed, besides >80char lines in _defs.h and _regs.h, checkpatch is happy. - Also, signal stat acquisition was made to comply with the DVB API ways to do these things. Permission to reuse and mainline the driver code was formally granted by Ralph Metzler <rjkm@metzlerbros.de>.

media: move dvb kAPI headers to include/media Except for DVB, all media kAPI headers are at include/media. Move the headers to it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
