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

2018-08-02T22:10:48+00:00

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.

media: dvb: i2c transfers over usb cannot be done from stack

2017-09-23T11:21:33+00:00

Since commit 29d2fef8be11 ("usb: catch attempts to submit urbs
with a vmalloc'd transfer buffer"), the AverMedia AverTV DVB-T
USB 2.0 (a800) fails to probe.

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

2016-11-18T17:00:22+00:00

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!

[media] dib3000mc: use pr_foo() instead of printk()

2016-11-18T11:48:42+00:00

The dprintk() macro relies on continuation lines. This is not
a good practice and will break after commit 563873318d32
("Merge branch 'printk-cleanups'").

So, instead of directly calling printk(), use pr_foo() macros,
adding a \n leading char on each macro call.

[media] dvb_frontend: pass the props cache to get_frontend() as arg

2016-02-04T18:27:30+00:00

Instead of using the DTV properties cache directly, pass the get
frontend data as an argument. For now, everything should remain
the same, but the next patch will prevent get_frontend to
affect the global cache.

This is needed because several drivers don't care enough to only
change the properties if locked. Due to that, calling
G_PROPERTY before locking on those drivers will make them to
never lock. Ok, those drivers are crap and should never be
merged like that, but the core should not rely that the drivers
would be doing the right thing.

[media] media: change email address

2016-01-25T14:01:08+00:00

Soon my dibcom.fr/parrot.com-address won't respond anymore.
Thus I'm replacing it. And, while being at it,
let's adapt some other (old) email-addresses as well.

[media] dvb: Get rid of typedev usage for enums

2015-06-09T20:47:35+00:00

The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.

So, let's do it.

This patch was generated by this shell script:

	for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

While here, make CodingStyle fixes on the affected lines.

The last one is actually due to a commented code. Let's rework
it, in order to remove the sparse warning without removing the
dead code, as it may be useful in the future.
