2021-11-19media: media dvb_frontend: add suspend and resume callbacks to dvb_frontend_opsLukas Middendorf1-2/+11
While dvb_tuner_ops already has dedicated suspend and resume callbacks, dvb_frontend_ops currently does not have them. Add those callbacks and use them for suspend and resume. If they are not set, the old behavior of calling sleep or init is used. This allows dvb_frontend drivers to handle resume differently from init, and suspend differently from sleep. No change is required for drivers not needing this functionality.

2019-08-14media: dvb_frontend.h: Fix shifting signed 32-bit value problemLuke Nowakowski-Krijger1-10/+11
Fix DVBFE_ALGO_RECOVERY and DVBFE_ALGO_SEARCH_ERROR use BIT macro which fixes undefined behavior error by certain compilers. Also changed all other bit shifted definitions to use macro for better readability.

2018-08-03media: dvb: represent min/max/step/tolerance freqs in HzMauro Carvalho Chehab1-1/+29
Right now, satellite frontend drivers specify frequencies in kHz, while terrestrial/cable ones specify in Hz. That's confusing for developers. However, the main problem is that universal frontends capable of handling both satellite and non-satelite delivery systems are appearing. We end by needing to hack the drivers in order to support such hybrid frontends. So, convert everything to specify frontend frequencies in Hz.

2018-08-02media: dvb: convert tuner_info frequencies to HzMauro Carvalho Chehab1-9/+10
Right now, satellite tuner drivers specify frequencies in kHz, while terrestrial/cable ones specify in Hz. That's confusing for developers. However, the main problem is that universal tuners capable of handling both satellite and non-satelite delivery systems are appearing. We end by needing to hack the drivers in order to support such hybrid tuners. So, convert everything to specify tuner frequencies in Hz. Plese notice that a similar patch is also needed for frontends.
