2016-04-13[media] au0828: remove unused macroGuennadi Liakhovetski1-1/+0
An V4L2_CID_PRIVATE_SHARPNESS macro is defined in the au0828 driver, but never used. Remove it. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-03-31[media] au0828: Fix dev_state handlingMauro Carvalho Chehab1-4/+5
The au0828 dev_state is actually a bit mask. It should not be checking with "==" but, instead, with a logic and. There are some places where it was doing it wrong. Fix that by replacing the dev_state set/clear/test with the bitops. As reviewed by Shuah: "Looks good. Tested running bind/unbind au0828 loop for 1000 times. Didn't see any problems and the v4l2_querycap() problem has been fixed with this patch. After the above test, ran bind/unbind snd_usb_audio 1000 times. Didn't see any problems. Generated media graph and the graph looks good."

2016-02-27[media] media: au0828 add enable, disable source handlersShuah Khan1-0/+5
Add enable_source and disable_source handlers. The enable source handler is called from v4l2-core, dvb-core, and ALSA drivers to check if the shared media source is free. The disable source handler is called to release the shared media source.

2016-02-10[media] au0828: move V4L2-specific code to au0828-core.cMauro Carvalho Chehab1-3/+17
Instead of having lots of #ifdefs inside au0828-core due to V4L2, move the dependencies to au0828-video.c. That allows removing all those ifdefs, as au0828-video is only compiled if CONFIG_VIDEO_AU0828_V4L2. This fixes the following warnings reported by Kbuild test with a random config with au0828 enabled, but V4L2 is disabled.

Embed video_device structs vdev and vbi_dev in au0828_dev. With this change, dynamic allocation and error path logic in au0828_analog_register() is removed as it doesn't need to allocate and handle allocation errors. Unregister path doesn't need to free the now static video_device structures, hence, changed video_device.release in au0828_video_template to point to video_device_release_empty.

2014-09-23[media] au0828: explicitly identify boards with analog TVMauro Carvalho Chehab1-0/+1
Right now, the au0828 driver uses .tuner to detect if analog tv is being used or not. By not filling .tuner fields at the board struct, the I2C core can't do decisions based on it. So, add a field to explicitly tell when analog TV is supported. No functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2014-08-22[media] au0828: Fix DVB resume when streamingMauro Carvalho Chehab1-2/+2
When DVB is streaming and suspend is called, it will call au0828_stop_transport(), with will clean the streaming flag. Due to that, stop_urb_transfer() will be called twice, causing an oops. So, we need another flag to be used at resume, telling it to restart DVB. While here, add a logic at stop_urb_transfer() to prevent it of being called twice, and convert the usb_streaming flag into boolean. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2014-05-26[media] au0828: reset streaming when a new frequency is setMauro Carvalho Chehab1-0/+2
As reported by Trevor, doing several opening/streaming/closing operations to the demux causes it to fail. I was able to simulate this bug too. I also noticed that, sometimes, changing channels with au0828, the same thing happens. Most of the issues seem to be due to some hardware bug, that causes the device to not fill all the URBs allocated. When the bug happens, the only known fix is to either replug the device, or to send an USB reset to it. There's also a hack a the au0828 driver that starts a thread that tries to reset the device when a package doesn't start with a sync. One of the culpits for this bad hardware behavior seem to be caused by the lack of stopping and restarting the stream every time a new channel is set. This patch warrants that the stream will be properly reset every time the set_frontend callback is called, partially solving the problem. A complete fix, however, would also need to check the PM conditions for the tuner and demux.

If the feed is not stopped on error, then the driver will be stuck so that it can never start feeding again.

2012-12-17[media] au0828: remove forced dependency of VIDEO_AU0828 on VIDEO_V4L2Michael Krufky1-0/+2
This patch removes the dependendency of VIDEO_AU0828 on VIDEO_V4L2 by creating a new Kconfig option, VIDEO_AU0828_V4L2, which enables analog video capture support and depends on VIDEO_V4L2 itself. With VIDEO_AU0828_V4L2 disabled, the driver will only support digital television and will not depend on the v4l2-core. With VIDEO_AU0828_V4L2 enabled, the driver will be built with the analog v4l2 support included. By default, the VIDEO_AU0828_V4L2 option will be set to Y, so as to preserve the original behavior.
