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

2017-06-06T10:50:19+00:00

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

2017-06-06T10:48:07+00:00

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

2017-06-06T10:47:40+00:00

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

2017-06-06T10:46:37+00:00

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

2017-06-06T10:45:56+00:00

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

2017-01-27T13:38:09+00:00

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 Of the 628 removed instances, 578 are outdated. The patch has been created with the following command without manual edits: git grep -l "675 Mass Ave\|59 Temple Place\|51 Franklin St" -- \ drivers/media/ include/media|while read i; do i=$i perl -e ' open(F,"< $ENV{i}"); $a=join("", ); $a =~ s/[ \t]*\*\n.*You should.*\n.*along with.*\n.*(\n.*USA.*$)?\n//m && $a =~ s/(^.*)Or, (point your browser to) /$1To obtain the license, $2\n$1/m; close(F); open(F, "> $ENV{i}"); print F $a; close(F);'; done Signed-off-by: Sakari Ailus

[media] au0828: use standard demod pads struct

2016-03-03T09:18:17+00:00

As we want au0828 to use the core function to create the MC graphs, use enum demod_pad_index instead of enum au8522_media_pads. Signed-off-by: Mauro Carvalho Chehab

[media] media framework: rename pads init function to media_entity_pads_init()

2016-01-11T14:19:03+00:00

With the MC next gen rework, what's left for media_entity_init() is to just initialize the PADs. However, certain devices, like a FLASH led/light doesn't have any input or output PAD. So, there's no reason why calling media_entity_init() would be mandatory. Also, despite its name, what this function actually does is to initialize the PADs data. So, rename it to media_entity_pads_init() in order to reflect that. The media entity actual init happens during entity register, at media_device_register_entity(). We should move init of num_links and num_backlinks to it. Signed-off-by: Mauro Carvalho Chehab
