OK.. I guess that was a misunderstanding on my part. I will split up the patch and re submit. Thanks, Franklin --- On Sun, 1/17/10, Devin Heitmueller dheitmuel...@kernellabs.com wrote: From: Devin Heitmueller dheitmuel...@kernellabs.com Subject: Re: Kworld 315U and SAA7113? To: Franklin

Devin, This is pretty good stuff.  A few questions/comments about your patch: The code has different GPIO configurations for the two analog modes. This is a bit unusual for an em28xx design.  Do you know what the difference is in terms of what GPIO7 controls? Unfortunately, I do not

Hi Franklin, I have no Kworld 315U here for testing, but your patch looked sane on my eyes. In order to merge this upstream, it would be better if you could submit it as two separate patches: the first one with the saa7115 changes to support re-energizing the device, and the second one with the

Attached is an updated diff for the Kworld 315U TV. I believe all the bugs have been worked out. I haven't figured out the remote control stuff and hopefully I will be able to get around to it some time. The sound issue was because I didn't have the right mplayer config so that is fixed as
