* media: dvb: convert tuner_info frequencies to HzMauro Carvalho Chehab2018-08-021-4/+3
| | | | | | | | | | | | | | | | | | | 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.

* [media] dvb_frontend: get rid of set_state ops & related dataMauro Carvalho Chehab2015-11-171-1/+0
| | | | | | | | | | | | | | | The get_state()/set_state and the corresponding data types (struct tuner_state and enum tuner_param) are old DVB interfaces that came from the DVBv3 time. Nowadays, set_params() provide a better way to set the tuner and demod parameters. So, no need to keep those legacy stuff, as all drivers that were using it got converted. With this patch, all kABI elements at dvb_frontend.h are now documented. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

Fix it by using unsigned int. While here, comment the two power management functions, while we don't add a code there to properly handle tuner suspend/resume.
