2022-11-21media: vidtv: Convert to i2c's .probe_new()Uwe Kleine-König1-3/+2
The probe functions doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>
2022-08-16i2c: Make remove callback return voidUwe Kleine-König1-3/+1
The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

2020-11-26media: vidtv: reorganize includesMauro Carvalho Chehab1-2/+3
- Place the includes on alphabetical order; - get rid of asm/byteorder.h; - add bug.h at vidtv_s302m.c, as it is needed by inux/fixp-arith.h Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-09-14media: vidtv: add basic support for DVBv5 statsMauro Carvalho Chehab1-1/+1
The current stats code is broken on so many ways. It ends reporting 0 for signal strengh, and the work queue doesn't run. If it would run, the code would crash. Fix such issues and add the minimum stuff for DVBv5 stats. Right now, only strength and cnr and UCB are implemented. pre/post BER stats will always return zero.

2020-09-14media: vidtv: fix frequency tuning logicMauro Carvalho Chehab1-5/+18
Right now, there are some issues at the tuning logic: 1) the config struct is not copied at the tuner driver. so, it won't use any frequency table at all; 2) the code that checks for frequency shifts is called at set_params. So, lock_status will never be zeroed; 3) the signal strength will also report a strong signal, even if not tuned; 4) the logic is not excluding non-set frequencies. Fix those issues.

2020-09-14media: vidtv: prefer using dev_foo() instead of pr_foo()Mauro Carvalho Chehab1-8/+9
It is better to use the higher level dev_foo() than pr_foo() for printks. Change them at vidtv at the more trivial places. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

2020-09-12media: vidtv: implement a tuner driverDaniel W. S. Almeida1-0/+427
The virtual DVB test driver serves as a reference DVB driver and helps validate the existing APIs in the media subsystem. It can also aid developers working on userspace applications. This dummy tuner should support common TV standards such as DVB-T/T2/S/S2, ISDB-T and ATSC when completed. Signed-off-by: Daniel W. S.
