media: dvb: represent min/max/step/tolerance freqs in Hz

2018-08-02T22:10:48Z

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.

Except for DVB, all media kAPI headers are at include/media. Move the headers to it. Signed-off-by: Mauro Carvalho Chehab

[media] dvb: make DVB frontend *_ops instances "const"

2016-11-18T17:00:22Z

These are immutable. Making them "const" allows the compiler to move them to the "rodata" section. Note that cxd2841er_t_c_ops cannot be made "const", because cxd2841er_attach() modifies it. Ouch!

gp8psk-fe: add missing MODULE_foo() macros

2016-11-18T10:06:38Z

This file was converted to a separate module at commit 7a0786c19d65 ("gp8psk: Fix DVB frontend attach"), because the DVB attach routines require it to work. However, I forgot to copy the MODULE_foo() macros from the original module, causing this warning: WARNING: modpost: missing MODULE_LICENSE() in drivers/media/dvb-frontends/gp8psk-fe.o Reported-by: Stephen Rothwell Fixes: 7a0786c19d65 ("gp8psk: Fix DVB frontend attach") Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Linus Torvalds

gp8psk: Fix DVB frontend attach

2016-11-13T18:02:22Z

The DVB binding schema at the DVB core assumes that the frontend is a separate driver. Faling to do that causes OOPS when the module is removed, as it tries to do a symbol_put_addr on an internal symbol, causing craches like: WARNING: CPU: 1 PID: 28102 at kernel/module.c:1108 module_put+0x57/0x70 Modules linked in: dvb_usb_gp8psk(-) dvb_usb dvb_core nvidia_drm(PO) nvidia_modeset(PO) snd_hda_codec_hdmi snd_hda_intel snd_hda_codec snd_hwdep snd_hda_core snd_pcm snd_timer snd soundcore nvidia(PO) [last unloaded: rc_core] CPU: 1 PID: 28102 Comm: rmmod Tainted: P WC O 4.8.4-build.1 #1 Hardware name: MSI MS-7309/MS-7309, BIOS V1.12 02/23/2009 Call Trace: dump_stack+0x44/0x64 __warn+0xfa/0x120 module_put+0x57/0x70 module_put+0x57/0x70 warn_slowpath_null+0x23/0x30 module_put+0x57/0x70 gp8psk_fe_set_frontend+0x460/0x460 [dvb_usb_gp8psk] symbol_put_addr+0x27/0x50 dvb_usb_adapter_frontend_exit+0x3a/0x70 [dvb_usb] From Derek's tests: "Attach bug is fixed, tuning works, module unloads without crashing.
