2014-09-22[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>
2014-08-21[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>
2014-08-21[media] au0828: use pr_foo macrosMauro Carvalho Chehab1-2/+3
Instead of using printk(KERN_foo, use pr_foo() macros. No functional changes. Note: we should do the same for dprintk(), but that would require to remove the dprintk levels. So, for now, let's not touch on it. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-08-21[media] au0828: add suspend/resume code for V4L2Mauro Carvalho Chehab1-0/+7
No timers should be enabled during suspend. So, stop them. At resume time, we should do the proper initialization for it to keep working. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-08-21[media] au0828: Add suspend code for DVBMauro Carvalho Chehab1-0/+2
The scheduled work should be cancelled during suspend. At resume time, we need to set the frontend again. So, add such logic to the driver. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-08-21[media] au0828: add au0828_rc_*() stubs for VIDEO_AU0828_RC disabled caseShuah Khan1-4/+11
Define au0828_rc_*() stubs to avoid compile errors when VIDEO_AU0828_RC is disabled and avoid the need to enclose au0828_rc_*() in ifdef CONFIG_VIDEO_AU0828_RC in .c files. Signed-off-by: Shuah Khan <shuah.kh@samsung.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-07-30[media] au0828: add support for IR on HVR-950QMauro Carvalho Chehab1-0/+11
HVR-950Q uses an I2C remote controller at address 0x47 (7-bits notation). Add support for it. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-25[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.

2014-01-13[media] au0828: Add option to preallocate digital transfer buffersTim Mester1-0/+4
Added command line parameter preallocate_big_buffers so that the digital transfer buffers can be allocated when the driver is registered. They do not have to be allocated every time a feed is started.

2014-01-13[media] au8028: Fix cleanup on kzalloc failTim Mester1-0/+2
Free what was allocated if there is a failure allocating transfer buffers. Stop the feed on a start feed error. The stop feed is not always called if start feed fails. 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.
