Checking that the captured field corresponds to the last required field depending on the requested field order before completing the buffer isn't enough. When the first field at stream start corresponds to the last required field, this would result in returning an interlaced buffer containing a single field. Fix this by keeping track of the fields captured in the buffer, and make sure that both fields are present for alternate field orders. Signed-off-by:

The video port doesn't support YUV formats. Disable it when the CCDC sink pad format is set to YUV instead of leaving it enabled and relying on downstream modules not to process data they receive from the video port. Experiments showed that this fixes some of the CCDC failures to stop, especially in BT.656 mode. Signed-off-by:

The CCDC can interleave fields into a single buffer when writing to memory. Support it. Signed-off-by:

The field order requested on the video node must match the field order at the connected subdevice source pad. Signed-off-by:

If the requested field order is not supported default to progressive as we can't guess how the user will configure the pipeline later on. Signed-off-by:

The isp_video_pix_to_mbus() and isp_video_mbus_to_pix() calls in isp_video_set_format() only access static fields of the isp_video structure. They don't need to be protected by a mutex. Signed-off-by:

Record the value returned by subdevs from s_stream(0) and handle stop failures when an error occurs. Signed-off-by:

The field order must match between the source and sink pads, or the sink pad field order must be NONE. This allows connecting an interlaced source to a bridge that has no hardware support for interlaced formats. Signed-off-by:

Add support for the V4L2_CID_TEST_PATTERN control. When the solid colour mode is selected, additional controls become available for setting the solid four solid colour components. Signed-off-by:

In many cases the test pattern has selectable values for each colour component. Implement controls for raw bayer components. Additional controls should be defined for colour components that are not covered by these controls. Signed-off-by:

Now that xc5000_set_params() is also called during resume, move the code that checks for the firmware to happen there. This way, the firmware will be loaded either for analog or digital TV when .resume callback is called. Signed-off-by: -

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: -

dev->dvb is always not null, as it is an area at the dev memory. So, checking if (dev->dvb) is always true. Instead of this stupid check, what the code wants to do is to know if the DVB was successully registered. Fix it by checking, instead, for dvb->frontend. It should also be sure that this var will be NULL if the device was not properly initialized. Signed-off-by: -

xc5000_set_params() is a bad name for a function that handles only digital TV. Rename it to xc5000_set_digital_params(), and proper name the generic function that works for both digital and analog. No functional changes. Signed-off-by: -

If a device suspends/hibertates with a station tuned, restore the tuner station at resume. Signed-off-by: -
Mauro Carvalho Chehab authored
As we need a function that reapply the last tuned radio, in order to do resume, split the code that validates and updates the internal priv struct from the ones that actually set radio and TV. A latter patch will add support for resume. Signed-off-by: -

As we'll be adding a code to resume tuner operation, we need to move the code that actually sets DTV on a separate function, to be called by the resume code. No functional changes, just code got moved. Signed-off-by: -

After xc5000 stops working, it waits for 5 seconds, waiting for a new usage. Only after that it goes to low power mode. If a suspend event happens before that, a work queue will remain active, with causes suspend to crash. Signed-off-by: -

While several tuners have some sort of suspend/resume implementation, this is currently mangled with an optional .sleep callback that it is also used to put the device on low power mode. Not all drivers implement it, as returning the driver from low power may require to re-load the firmware, with takes some time. Also, some drivers may delay it. So, the more coherent is to add two new optional callbacks that will let the tuners to directy implement suspend and resume callbacks if they need. Signed-off-by: -

Suspend/resume conditions can be very tricky. Add some info printk's to help tracking what's happening there. Signed-off-by: -
Mauro Carvalho Chehab authored
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: -

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: -

The STREAM_ON state is used by s_format callback, but the driver never sets it. Fix it. This will also be needed in order to handle suspend/resume ops. Signed-off-by: -

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: -

At resume, we should restore the register contents. So, reenable the bridge and GPIO settings. Signed-off-by: -

Trying to make au0828 to suspend can do very bad things, as the polling Kthread is not handled. We should disable it during suspend, only re-enabling it at resume. Still, analog and digital TV won't work, as we don't reinit the settings at resume, but at least it won't hang. Signed-off-by: -

It doesn't make sense to handle an IR code given before suspending after the device resume. So, turn off IR int while suspending. Signed-off-by: -
Mauro Carvalho Chehab authored
As the RC kthread can re-enable IR int, we should first cancel the kthread and then disable IR int. While here, remove a temporary debug printk. Signed-off-by: -
Mauro Carvalho Chehab authored
When the DVB code sets the frontend, it disables the IR INT, probably due to some hardware bug, as there's no code there at au8522 frontend that writes on register 0xe0. Fixing it at au8522 code is hard, as it doesn't know if the IR is enabled or disabled, and just restoring the value of register 0xe0 could cause other nasty effects. So, better to add a hack at au0828-input polling interval to enable int, if disabled. Signed-off-by:
