2018-05-05media: frontends: fix ops get_algo()'s return typeLuc Van Oostenryck1-1/+1
The method dvb_frontend_ops::get_frontend_algo() is defined as returning an 'enum dvbfe_algo', but the implementation in this driver returns an 'int'. Fix this by returning 'enum dvbfe_algo' on drivers.

2018-03-05media: dvb-frontend/mxl5xx: add support for physical layer scramblingDaniel Scheller1-1/+33
The MaxLinear MxL5xx has support for physical layer scrambling, which was recently added to the DVB core via the new scrambling_sequence_index property. Add required bits to the mxl5xx driver. Picked up from dddvb master, commit 5c032058b9ba ("add support for PLS") by Ralph Metzler <rjkm@metzlerbros.de>, adapted to the different naming of the pls property (pls vs. scrambling_sequence_index).

2017-12-28media: move dvb kAPI headers to include/mediaMauro Carvalho Chehab1-1/+1
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>
2017-12-11media: mxl5xx: fix tuning logicMauro Carvalho Chehab1-8/+1
The tuning logic is broken with regards to status report: it relies on a previously-cached value that may not be valid if re-tuned. Change the logic to always read the status. Acked-by: Daniel Scheller <d.scheller@gmx.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2017-08-20media: dvb-frontends: MaxLinear MxL5xx DVB-S/S2 tuner-demodulator driverDaniel Scheller1-0/+1873
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>.
