media: au8522: declare its own pads

2018-09-17T17:16:19Z

As we don't need anymore to share pad numbers with similar drivers, use its own pad definition instead of a global model. Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l2: taint pads with the signal types for consumer devices

2018-09-17T17:16:19Z

Consumer devices are provided with a wide different range of types supported by the same driver, allowing different configutations. In order to make easier to setup media controller links, "taint" pads with the signal type it carries. While here, get rid of DEMOD_PAD_VBI_OUT, as the signal it carries is actually the same as the normal video output. The difference happens at the video/VBI interface: - for VBI, only the hidden lines are streamed; - for video, the stream is usually cropped to hide the vbi lines.

media: v4l2: remove VBI output pad

2018-09-17T17:16:19Z

The signal there is the same as the video output (well, except for sliced VBI, but let's simplify the model and ignore it, at least for now - as it is routed together with raw VBI). Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: au8522: remove duplicate code

2018-05-28T20:26:38Z

This code has been there for nine years now, and it has been working "good enough" since then [1]. Remove duplicate code by getting rid of the if-else statement.

[media] au8522: fix lock detection to be more reliable

2017-06-06T10:50:19Z

Only looking at the lock register causes the status to float between locked and not locked when there is no signal. So improve the logic to also examine the state of the FSC PLL, which results in the lock status being consistently reported.

[media] au8522: remove note about VBI not being implemented

2017-06-06T10:48:07Z

I got this working a couple of years ago. Remove it from the list of known issues. Signed-off-by: Devin Heitmueller Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] au8522: rework setup of audio routing

2017-06-06T10:47:40Z

The original code was based on my reverse engineering of an I2C trace of the Windows driver. Now that I know what the registers actually do, restructure the code a bit, removing some unneeded register programming and fixing the sequencing of operations. This reduces the time it takes to change inputs from 1300ms down to 600ms (as measured by "time v4l2-ctl -i 0") Note this does not address outstanding issues related to the management of the module clocks and power control for the various blocks, which will be done in a separate patch.

[media] au8522: don't touch i2c master registers on au8522

2017-06-06T10:46:37Z

Some stray lines got inserted into the driver when I reverse engineered the I2C traffic (at the time I didn't know what the registers did). It turns up these registers muck with the onboard I2C master, which we don't use since we instead use the I2C gate. Remove the lines which can actually interfere with the operation of the bus.

[media] au8522: don't attempt to configure unsupported VBI slicer

2017-06-06T10:45:56Z

Since we don't suppoort sliced VBI with the au0828/au8522, there is no need to configure the au8522 VBI slicer, which because of the coefficients requires a large amount of i2c traffic. Remove the relevant code. Note that this has no effect on raw VBI support, which is currently the only supported way to access VBI on this device.

[media] media: Drop FSF's postal address from the source code files

2017-01-27T13:38:09Z

Drop the FSF's postal address from the source code files that typically contain mostly the license text. Of the 628 removed instances, 578 are outdated.
