[PATCH 00/11] Assorted DVB and TV patches

[PATCH 00/11] Assorted DVB and TV patches

[Bradford Love]

Hello,

Attached here is a series of accumlated fixes from integrations
and deployments.

The first five patches are related to fixing issues with a
variety of analog video formats.

The si2168 i2c timeout patch is something that has been found
to be critical on a variety of ARM platforms and Nvidia SOC.
Something in these platforms has USB i2c not consistently responding
within the embedded deadline in the driver.

There are two firmware fixes. With Hauppauge hardware fw 4.0-11 si2168
devices definitely lose warm state and cannot function after sleep.
The saa7164 REV2 firmware had an incorrect filename and has been fixed.

Last up is adding some new Hauppauge USB id's and removing an invalid
analog input from the Hauppauge DVB DualHD.

Addressing checkpatch warnings:
- 0001 palN is not misspelled
- 0003 adding dprintk like driver already does



Regards,

Bradford

[PATCH 04/11] cx231xx: Fix AGC levels for NTSC-M

[Bradford Love]

Windows uses the implemented command sequence to set AGC for NTSC-M.
The previous Linux values work, mostly, but on some embedded
platforms NTSC-M is very unstable. The Windows default values
completely fix any signal stability issues and produce clear iamge.

[PATCH 05/11] au0828: Fix green screen in analog

[Bradford Love]

When the driver was converted to VB2 the original function to fix
green frame detection was removed and a default vb2 dqbuf function
was used instead. This vb2 dqbuf function leads to green frames not
being detected and correupting stream captures.

The vidioc_dqbuf function checks the greenscreen flag, and, if set
resets the stream to discard the green frame and decode a real frame.

Please replace those last 4 lines with:

	return vb2_ioctl_dqbuf(file, priv, b);

It's cleaner that way.

was used instead. This vb2 dqbuf function leads to green frames not
being detected and correupting stream captures.

The vidioc_dqbuf function checks the greenscreen flag, and, if set
resets the stream to discard the green frame and decode a real frame.

Changes since v2:
 - Fixed extra blank line
 - removed now unused variable
Changes since v1:
- swtiched to called vb2_ioctl_dqbuf directly after checking green screen

[PATCH 06/11] si2168: Fix i2c command timeout on embedded platforms

[Bradford Love]

On many embedded platforms i2c responses through USB are not returned
as quickly, plus constantly banging on the i2c master receive essentially
deadlocks the driver. Inserting a 3ms delay between i2c receive calls
and extending the timeout fixes all tested platforms.

[PATCH 09/11] au0828: Add new Hauppauge HVR1265 and ImpactVCB-e

[Bradford Love]

New HVR1265 and ImpactVCB-e devices are PCIe baords
with USB controller and essentially embedded
Hauppauge 950Q.

HVR1265 - digital+analog TV, S-Video, and audio inputs
ImpactVCB-e - Composite, S-Video, and audio inputs

This also fixes AU8522_COMPOSITE_CH4, which was missing
from video routing.

[PATCH 11/11] em28xx: remove tuner type from Hauppauge DVB DualHD

[Bradford Love]

This reverts a patch which was perhaps inadvertently added.

This was changed during the 5.15-rc4 merge. The faulty commit appears
lost in the pull request somehow, I cannot find it to check the
explanation.

commit c52e7b855b33 ("Merge tag 'v5.15-rc4' into media_tree")

There was nothing wrong with this device and no reason to moodify the
board profile. The DVB capabilities are added via dvb_module_probe.
Additionally, the device contains *zero* analog inputs, so I'm not
sure why one was added.

Re: [PATCH 00/11] Assorted DVB and TV patches

[Hans Verkuil]

Hi Brad,

Thank you for this cleanup series!

I'll take them all, except for the "au0828: Fix green screen in analog" patch,
which needs a v2. So no need to post a v2 of the whole series, just post a v2
of that au0828 patch.

Regards,

	Hans

BTW, for future reference, please prefix media patches with "media: " in the Subject
line. I added it manually for these patches.

Re: [PATCH 00/11] Assorted DVB and TV patches

[Bradford Love]

Hi Hans,

Thank you for grabbing these patches. I will generate a new au0828
patch and get that v2 sent out. I noticed the media: subject issue too
late for the first couple series I mailed in, but will add from now
on.

Regards,

Bradford
