2013-03-24[media] go7007-loader: add support for the other devices and move fw filesHans Verkuil
Add support for the other devices that need to load the boot firmware. All firmware files are now placed in a single go7007 directory. Also remove the device_extension_s stuff: this is clearly a left-over from the olden days.

2013-03-24[media] go7007-loader: renamed from s2250-loaderHans Verkuil
All s2250 names are renamed to go7007. This will be the generic go7007 firmware loader for any go7007 device, not just for the s2250/1. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-03-24[media] go7007: drop struct go7007_fileHans Verkuil
Remove struct go7007_file: all fields contained in that struct are moved to the go7007 struct since they are really global values. The lock has just been deleted (what's the point of a per-fh lock??). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-24[media] go7007: set up the saa7115 audio clock correctlyHans Verkuil

2013-03-24[media] go7007: simplify the PX-TV402U board ID handlingHans Verkuil
There really is no need to split out the board IDs for each tuner. That's what the tuner_type is for, after all. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-24[media] go7007: standardize MPEG handling supportHans Verkuil
The go7007 produces elementary streams, so we shouldn't use the STREAM_TYPE control, since that is for multiplexed streams. Instead use V4L2_PIX_FMT_MPEG1/2/4. Initially set up all the values for MPEG-2 dvd-mode, and select the dvd_mode field if those values match that setup precisely. Clean up lots of obsolete code relating to the custom ioctls for the MPEG support. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-24[media] go7007: tuner/std related fixesHans Verkuil
- The Adlink is initially detected as a sensor board, so the driver config is set up as if it was a sensor. Later the driver discovers that it really is a video capture card and that means that the driver configuration has to be updated for a PAL/NTSC capture card. - Setup the correct initial std based on the TV tuner type. - Remember the exact std the user selected, don't map it to STD_PAL or NTSC. - Use v4l2_disable_ioctl to disable ioctls based on the board config and drop a lot of checking code in each of those ioctls since that is no longer needed. - enum_input should use tvnorms to fill its std field. - configure the input, std and initial tuner frequency at driver initialization. - fix std handling in the s2250 driver. - the code handling scaling for devices without a scaler was broken. This is now fixed. - correctly set readbuffers and capability in g/s_parm. - remove the bogus test for capturemode in s_parm. - correctly implement enum_framesizes/intervals.

2013-03-24[media] go7007: fix unregister/disconnect handlingHans Verkuil
- use the v4l2_device's release() callback - remove the unnecessary ref_count - don't free usb data structures on disconnect, only do that in the final release callback. This is the correct way in order to safely handle disconnect and removal of modules. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-24[media] go7007: remember boot firmwareHans Verkuil
Don't load it everytime you stop encoding. Instead remember it. Another reason for not loading it every time is that this could be called from within the release() file operation, which turns out to be deadly.

2013-03-24[media] go7007: fix DMA related errorsHans Verkuil

2013-03-24[media] go7007: remove current_normHans Verkuil

2013-03-24[media] go7007: switch to standard tuner/i2c subdevsHans Verkuil
Instead of using the wis-* drivers we now use the standard 'proper' subdev drivers. The board configuration tables now also list the possible audio inputs, this will be used later to implement audio inputs. Special mention deserves a little change in set_capture_size() where the height passed to s_mbus_fmt is doubled: that is because the saa7115 driver expects to see the frame height, not the field height as the wis_saa7115 driver did. Another change is that the tuner input is moved from last to the first input, which is consistent with the common practice in other video drivers.

2013-03-24[media] sony-btf-mpx: the MPX driver for the sony BTF PAL/SECAM tunerHans Verkuil
The Sony BTF PG472Z has an internal MPX to deal with mono/stereo/bilingual audio. This is split off from the wis-sony-tuner driver that is part of the go7007 driver as it should be a separate i2c sub-device driver. The wis-sony-tuner is really three i2c devices: a standard tuner, a tda9887 compatible demodulator and this mpx. After this patch the wis-sony-tuner can be replaced by this driver and the standard tuner driver.

2013-03-24[media] tuner: add Sony BTF tunersHans Verkuil
This adds support for three Sony BTF tuners: TUNER_SONY_BTF_PG472Z: PAL+SECAM TUNER_SONY_BTF_PK467Z: NTSC-M-JP TUNER_SONY_BTF_PB463Z: NTSC-M These come from the go7007 staging driver where they were implemented in the wis-sony-tuner i2c driver. Adding support for these tuners to tuner-types.c is the first step towards removing the wis-sony-tuner driver.

2013-03-24[media] go7007: fix i2c_xfer return codesHans Verkuil

2013-03-24[media] saa7115: improve querystd handling for the saa7115Hans Verkuil

2013-03-24[media] saa7115: add config flag to change the IDQ polarityHans Verkuil
Needed by the go7007 driver: it assumes a different polarity of the IDQ signal, so we need to be able to tell the saa7115 about this. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-24[media] v4l2-ctrls: add V4L2_CID_MPEG_VIDEO_REPEAT_SEQ_HEADER controlHans Verkuil

2013-03-24[media] v4l2-ioctl: check if an ioctl is validHans Verkuil
Just checking if the op exists isn't correct, you should check if the ioctl is valid (which implies that the op exists as well). One exception is g_std: if current_norm is non-zero, then the g_std op may be absent. This sort of weird behavior is one of the reasons why I am trying to get rid of current_norm. This patch fixes the case where the g/s_std op is set, but these ioctls are disabled. This can happen in drivers supporting multiple models, some that have TV input (and support the STD API) and some that have a sensor (and do not support the STD API). In the latter case qv4l2 would still show the Standards combobox. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-24[media] v4l2-core: add code to check for specific opsHans Verkuil
This patch adds a v4l2_subdev_has_op() macro and a v4l2_device_has_op macro to quickly check if a specific subdev or any subdev supports a particular subdev operation. This makes it easy for drivers to disable certain ioctls if none of the subdevs supports the necessary functionality.
