2009-06-23V4L/DVB (12104): ivtv/cx18: fix regression: class controls are no longer seenHans Verkuil1-0/+2
A previous change (v4l2-common: remove v4l2_ctrl_query_fill_std) broke the handling of class controls in VIDIOC_QUERYCTRL. The MPEG class control was broken for all drivers that use the cx2341x module and the USER class control was broken for ivtv and cx18. This change adds back proper class control support.

2009-06-17V4L/DVB (11951): cx18: Add DVB-T support for the Leadtek WinFast DVR3100 HAndy Walls2-14/+57
This adds support for DVB-T on the Leadtek DVR3100 H and should also get analog TV capture from the tuner working properly as well. DVB-T 6 MHz and 8 MHz have been tested and verified to work by Terry Wu of Leadtek. DVB-T 7 MHz has also been verified working with a change developed by Terry to the tuner-xc2028.c driver. Special thanks go to Terry Wu <terrywu2009@gmail.com> of Leadtek who provided the needed information and testing to get digital TV working for the Leadtek DVR3100 H.

Also have the initial color sub-carrier freq paramter use the src decimation ratio per the documentation, instead of the actual crystal/pixel clock ratio.

AFE config Ensure the variable gain amplifier gain for SIF is driven by the audio deocder and not the video decoder.

CX18_AUDIO_ENABLE register Toggle the AI1 mux when changing the CX18_AUDIO_ENABLE register. It's hard to reliably tell when we have written to this register successfully unless we change some bits we know we can read back. The AI mux bits always read back what we wrote to them, so force them to toggle whenever we have to write to the register, so we can tell we wrote to the register successfully.
